Art and Storytelling Flourished

The Bronze Age saw an explosion of creativity that, like most aspects of the era, varied by region as civilizations developed at different speeds and with their own styles and techniques. In Mesopotamia (around modern-day Iraq), sculptors carved detailed figures from stone and bronze, while in the Aegean world, particularly among the Minoans on the island of Crete (in modern-day Greece), pottery was a canvas as much as it was a vessel. Even everyday items such as frying pans were detailed with elegant nature scenes and designs. Bronze bells, meanwhile, were a staple of musical rituals in late Bronze Age China, around 1050 BCE, believed to symbolize virtue.

It was also, despite limited writing systems, a significant time for literature. The most famous work to survive from the Bronze Age — and one of the oldest surviving works of literature — is The Epic of Gilgamesh. First written on clay tablets in cuneiform in ancient Sumer around 2100 BCE, the story follows the tale of Gilgamesh, the king of the city of Uruk. The story and its themes of mortality, Mesopotamian religious beliefs, and societal values are considered foundational aspects of the heroic epic genre.

Civilizations Rose

Permanent settlements and early cities existed long before the Bronze Age, but the era saw the rise of the first organized and complex urban societies. These were densely populated, politically organized, and connected through trade, communication, and technologies such as the mastery of bronze metallurgy and irrigation systems. 

In Mesopotamia — often called the cradle of civilization — the Sumerian city-state Uruk flourished in 3500 BCE. Estimates of its population vary, but at its peak, it’s thought to have been home to between 50,000 and 80,000 people. It introduced key features of urban life: monumental temples that doubled as religious and administrative centers, a centralized government led by priests and kings, and the invention of cuneiform writing for managing trade and resources. The cities of Babylon and Nineveh later expanded these innovations, developing vast trade networks and astronomical records. The Babylonians also pioneered a comprehensive legal system with the Code of Hammurabi, established around 1750 BCE.

In South Asia, the Indus Valley Civilization (modern-day Pakistan and North India) planned cities such as Harappa and Mohenjo-Daro with remarkable precision, with uniform brickwork, public baths, and complex drainage that set the standard for urban sanitation. In the Aegean, the Minoans on Crete built a 150,000-square-foot palace complex in the city of Knossos, and were pioneers of maritime trade and early syllabic writing systems.

Religion and Ritual Shaped Everyday Life

In the Bronze Age, religion was often observed at temples, but it certainly wasn’t confined to them. Religion and its accompanying rituals were woven throughout much of daily life, as most people believed their fates were influenced by supernatural forces. In regions such as ancient Britain, where the Bronze Age started around 2500 BCE, communities such as the Beaker people held sacrifices to the gods at stone circles. In Egypt, meanwhile, religious life centered around the afterlife: Massive tombs and ornate burial customs demonstrated a belief in a world after death. Bronze Age religious spaces were often natural sites, too: The River Thames, for instance, served as a sacred place where people left thousands of objects, believed to be offerings to its spirit.

It Collapsed Fairly Quickly

After thriving for centuries, the advanced and interconnected civilizations of the Bronze Age began a collapse sometime around 1200 BCE that took just a few decades, ending in about 1150 BCE. Cities across the eastern Mediterranean were abandoned or destroyed and trade routes crumbled. In Mycenaean Greece, palace complexes were destroyed. The Hittite Empire in Anatolia (modern-day Turkey) vanished. Even Egypt, though it partially survived, was badly weakened and never regained its former power. 

Historians have pointed to a variety of potential and overlapping causes, including drought, famine, earthquakes, and invasion, but the scale and suddenness of the collapse is difficult to fully account for. Though the Bronze Age collapse was sudden in the timeline of history, its impact was long-lasting. Many regions entered a so-called “dark age,” with fewer historical records — writing systems such as the Aegeans’ Linear B vanished — and simpler societies. The shadow lingered until the Iron Age was well established in many regions by around 1000 BCE. Iron was more accessible than copper, and using it to make steel meant tools and weapons were stronger. A boost in agriculture helped population growth, fueling the rise of new states and the gradual return of urban life, trade, and culture.

Midday

By late morning, the farmer was busy in the fields. Whether plowing, sowing, or harvesting, they often sang songs or worked alongside the rest of the family, making the long hours a bit more bearable. Animals were fed, irrigation channels were checked, and grain was carefully stored for the future. The work was physically demanding, with little time for breaks, except perhaps a short midday rest and a quick snack.

Meanwhile, the pharaoh’s day was generally filled with matters of state. They met with high-ranking officials, reviewed reports from distant provinces, and made important decisions about military strategies, construction projects, or new decrees — decisions that scribes quickly recorded. The pharaoh was seen as a living god, and as such their duties were deeply connected to religion. They often visited temples or oversaw grand state ceremonies, all designed to maintain ma’at — the divine balance that kept the universe in harmony.

The scribe’s midday looked a bit different. Sitting cross-legged with a papyrus scroll on their lap, they might have copied tax records, written land deeds, or transcribed religious texts, using reed pens and ink. In addition to their writing tasks, they might have overseen operations at a grain warehouse, checked inventories, or accompanied inspectors to ensure tax compliance in the nearby villages.

Afternoon

As the afternoon sun climbed higher, the farmer pressed on with their work. They might have reinforced irrigation dikes, tended to livestock, or gathered reeds (to make baskets or mats) or papyrus (to make paper) along the Nile. The river shaped every part of their world — its annual flooding, known as inundation, could wash away homes, but it also left behind rich, fertile soil that made farming possible. During the months when fields were underwater, many farmers were called to help with state projects such as digging canals or even working on temple construction. 

The scribe’s afternoon sometimes took them away from their writing board and out into the field. They often accompanied officials to survey land, checked on tax records, and delivered documents between government offices. Scribes were responsible for various administrative tasks, including recording census data, managing tax records, and drafting legal documents. 

Scribes didn’t live in luxury, but their education offered them a level of stability and social status that few others had. Even with long hours and modest pay, the role came with opportunity — scribes could ascend the ranks of bureaucracy, with some rising to prominent positions such as vizier (a high-ranking political official) or even pharaoh, such as Horemheb in the 14th century BCE.

Meanwhile, the pharaoh’s duties extended into the afternoon with ceremonies, council meetings, or visits to key sites. Their duties included touring construction projects, presiding over temple rituals, and meeting with diplomats bearing gifts and tributes. Even when they weren’t issuing decrees or overseeing matters of state, their presence carried symbolic weight — every move reinforcing their divine role in maintaining harmony across the land.

Evening 

As evening settled over Egypt, the pace of daily life slowed. The farmer returned to their mud-brick home, tired from the day’s labor, and often sat down to a simple meal with the family — lentils, flatbread, vegetables, and, if they were fortunate, some fish or duck. The evening hours were quiet, filled with conversation, stories, and a bit of rest before the cycle began again at dawn.

The scribe’s work came with some comforts, but their schedule was still shaped by the responsibilities of recordkeeping and administration. They ended their long work day by cleaning their tools and putting away scrolls. At home in their apartment complex near the mortuary or temple, they might have dined on a dinner of vegetables, bread, meat, and beer and then spend time reading, writing, or relaxing with music and family.

Even with the privileges of royalty, the pharaoh’s day often followed a similar rhythm of tradition, ceremony, and decision-making. At the vibrantly decorated palace, the ruler’s dinner was an elaborate affair, prepared by a team of cooks and often served alongside music and entertainment. Afterward, they sometimes meet with priests or advisers, or simply wound down in private quarters for the night.

622 CE

The foundation of Islam is unusually well documented compared to other major religions. In 610 CE, the Prophet Muhammad received his first revelation, marking the birth of the religion. Then, in 622 CE, he completed his migration from Mecca to Medina — known as the Hijra — transforming a small religious movement into a unified community that became the foundation of the Islamic state. 

Within a century of the Hijra, Islam had expanded from Spain to the borders of China. The Islamic civilization grew to become a global powerhouse for roughly a millennium, at the forefront of trade, invention, and innovation. Islamic scholars flourished, turning the civilization into the leading center for science, medicine, philosophy, astronomy, math, and more, reshaping the intellectual, economic, and political architecture of the globe.

1492

For the whole of human history until the late 15th century, the Eastern and Western hemispheres had largely evolved in isolation. That separation ended forever after Christopher Columbus made landfall in what is now the Bahamas on October 12, 1492. What followed — now known as the Columbian Exchange — was one of the most transformative social and ecological events in history. Crops, animals, and diseases moved in both directions. Old World illnesses may have killed as many as 90% of the pre-Columbian population within a century. European colonialism followed, reshaping the entire world. No single voyage in history had greater consequences for more people.

1760

Historians disagree as to precisely when the Industrial Revolution began, but textbooks typically put the start around 1760. It was a pivotal year, with agrarian economies giving way to a world dominated by industry, machine manufacturing, and coal. Mills and steam engines, and technologies such as the spinning jenny, brought about the mechanization of manufacturing, which in turn led to the rise of the factory system, railways, steamships, rapid growth of cities, and ultimately modern global capitalism. Perhaps no development since the agricultural revolution altered the conditions of human existence to such an extent — and the environmental consequences, including large-scale carbon emissions and the transformation of ecosystems, are still unfolding today. 

1945

When World War II ended in 1945, it didn’t only mark the conclusion of the deadliest conflict in human history. It ended the era of European global dominance that had begun with Columbus in 1492. For the exhausted, financially ruined European powers — most notably Great Britain and France — the end of the war marked the beginning of the decline of their colonial empires. 

That same year, the United Nations was founded and the Cold War began. Two superpowers — the United States and the Soviet Union — divided the world into competing spheres that fundamentally changed the political outlook of the world. The end of the war had introduced a permanent new condition into human affairs: the possibility of civilizational self-destruction. When the atomic bomb was dropped on Hiroshima on August 6, 1945, the world opened its eyes to a stark new reality that has shaped every geopolitical calculation from that moment until the present day. 

Honorable Mentions

~10,000 BCE

No single year in the prehistoric period can be pinpointed precisely, but around 10,000 BCE, human communities began cultivating crops and domesticating animals. The agricultural revolution produced food surpluses, making possible larger populations, specialized labor, trade, writing, cities, armies, and governments. 

~3200 BCE

The development of cuneiform script in ancient Mesopotamia was arguably the single most consequential intellectual development in human history, making it possible to record laws, coordinate trade, accumulate knowledge across generations, administer complex states, and record history itself. 

539 BCE

The Persian conquest of Babylon by Cyrus the Great created the first true superpower civilization, linking the Mediterranean, Near East, Central Asia, and South Asia under a single administration.

1206 

Genghis Khan’s unification of the Mongols launched one of the largest contiguous land empires in history. It was enormously destructive — the sack of Baghdad in 1258 ended the Islamic golden age — but the Pax Mongolica also created the first transcontinental trade network, opening sustained exchange between the East and West.

1789

When the French Revolution began with the storming of the Bastille, it ended the French monarchy and promulgated the ideology of liberty, equality, and popular sovereignty across Europe and beyond. The revolution played a large part in ending the divine right of kings as a governing principle and set the template for democratic revolutions for the next two centuries.

1859

No book of the 19th century did more to reshape human understanding of our place in nature than Charles Darwin’s “On the Origin of Species,” published in 1859. Darwin’s theory of evolution by natural selection transformed biology, medicine, and our understanding of human origins, while challenging the religious and philosophical frameworks that had long governed Western thought.

How the Ancients Shaped the Week

The seven-day week has endured for thousands of years, surviving empires, revolutions, religious shifts, and even a few determined attempts to replace it. Its origins lie in a mix of astronomy, astrology, religion, and ancient practicality — with a healthy dose of historical debate.

Many historians trace the roots of the seven-day week to ancient Mesopotamia, home to some of the world’s earliest astronomers. The Babylonians closely observed the sky and attached special importance to the number seven, partly because they recognized seven major celestial bodies moving independently: the sun, the moon, Mercury, Venus, Mars, Jupiter, and Saturn. Today, we know the sun and moon aren’t planets, but in the ancient world they were grouped together with the five planets visible to the naked eye. 

The Babylonians also used a lunar calendar, and the phases of the moon may have helped shape the structure of the week. A full lunar cycle lasts about 29.5 days, which can be divided into four roughly seven-day phases. Some scholars believe Mesopotamian societies, including the Sumerians and Babylonians, used these quarter-moon intervals as the basis for a recurring seven-day cycle, and this is one basis for our current week.

However, scholars continue to debate exactly how much the modern week is influenced by this Babylonian practice versus by ancient Jewish tradition. The biblical creation story helped cement the importance of the number seven in Jewish culture: According to Genesis, God created the world in six days and rested on the seventh. That seventh day became the Sabbath, a recurring day of rest and worship. Unlike many earlier calendars tied directly to lunar phases, the Jewish week evolved into a continuous repeating cycle independent of the moon.

The Romans initially followed a different system entirely. For centuries, Roman civil life revolved around an eight-day market cycle. But as astrology from the eastern Mediterranean spread through the Roman Empire, the seven-day planetary week became increasingly popular. Each day was associated with one of the seven classical planets.

How We Got to Seven Days

In 321 CE, Roman Emperor Constantine officially established the seven-day week in the Roman calendar, helping spread it across Europe. Some of those planetary names still survive in English today. Sunday honors the sun, Monday the moon, and Saturday Saturn. The names for the other weekdays reflect Anglo-Saxon names for Norse deities. Tuesday comes from Tiw, a Norse war god linked with Mars. Wednesday honors Odin (or Woden), associated with Mercury. Thursday derives from Thor, connected with Jupiter, while Friday honors Frigg, tied to Venus.

Not every culture embraced seven-day weeks, however. Ancient Egypt sometimes used 10-day cycles, while parts of West Africa followed four-day market weeks. Revolutionary governments also occasionally tried to reinvent the calendar. During the French Revolution, reformers introduced a 10-day week intended to break with religious tradition and make timekeeping more “rational.” (All the days and months were named after elements in nature.) Soviet officials later experimented with five-day and six-day workweeks in an effort to maximize industrial productivity; the days were even color-coded. Neither experiment lasted.

The persistence of the seven-day week is remarkable, considering how arbitrary the unit really is. Unlike days, months, or years, a week is fundamentally a human invention — one shaped by ancient sky-watchers and thousands of years of habit.

The Roman Workday Ended at Noon

The ancient Romans didn’t have clocks they could use to count the hours of the day. Instead, they kept track of the time using the position of the sun, and employed devices such as sundials to divide the day and night into 12 evenly spaced units called “hora” (hours). Since tracking the sun was the Roman citizen’s principal timekeeping method, the workday was structured around solar positions that were easy to measure with the naked eye, such as sunrise, noon, and sunset. For this reason, a typical citizen would usually start their workday at dawn, which marked the first “hora” of the day, and stop working at noon. This left the rest of the afternoon open for leisure, and citizens from all levels of Roman society would spend that time attending sporting events, theatrical performances, and the all-important public baths.

The Roman People Loved to Gamble

A love of gambling extended to all levels of ancient Roman society. Less-wealthy citizens would place bets on a wide variety of board games and dice games, which they played in taverns, city streets, and other public spaces, while the rich would build private gaming rooms in their homes. Romans would also frequently bet on the outcomes of gladiator fights and chariot races. (For the most part, only men were permitted to gamble, though women were allowed to participate in games of chance during special festivals.) Even the Roman emperors got in on the action. Rulers such as Augustus and Nero were known for their gaming habits, and for betting small fortunes on a single throw of the dice. Roman Emperor Claudius even had a custom-made carriage built with a gaming table so that he could gamble while traveling.

The Roman Forum Was the Center of Public Life

With its location right in the middle of the city, the Roman Forum was quite literally the center of everyday life in ancient times. It was where the typical Roman citizen could shop, talk, and find entertainment. It was also the site of most of the city’s public gatherings, the Roman courts of law, and the meeting place of the Roman Senate. What’s more, the forum housed some of Rome’s most important religious sites, including multiple temples dedicated to Roman deities. In other words, if you were a Roman citizen, chances were good that you’d be making frequent visits to the forum for everything from daily errands to grand citywide ceremonies.

There Was a Temple Where Citizens Could Go to Worship Caesar

One prominent temple in the Roman Forum was dedicated not to the worship of a mythological god, but to the former dictator of Rome, Julius Caesar. During the funeral games held in Caesar’s honor shortly after his assassination in 44 BCE, a comet appeared in the sky for seven days, which the Roman populace interpreted as a divine omen that Caesar’s soul had ascended to the status of divinity. This popular belief that Caesar had become a god was codified into law two years later in 42 BCE, when the Roman Senate officially declared him a deity. After this, a temple was built in the forum in Caesar’s honor. It even had an altar where Roman citizens would offer sacrifices to the deified leader, just as they would to supernatural Roman gods such as Jupiter and Saturn.

An Alternative Theory

Historical sources are vague when it comes to the tersorium — it seems that few Romans found it noteworthy enough to warrant a weighty text or treatise. This has caused some modern scholars to question the actual purpose of the tool. We know it was found in most public latrines, but was it used for the cleaning of numerous behinds or simply for scrubbing the latrine itself, much like a modern toilet brush? 

The greatest proponent of the latter theory is Austrian archaeologist Gilbert Wiplinger. He argues that the popular idea that Romans used the tersorium to clean their behinds is incorrect. Having reviewed ancient textual sources, including Seneca and Martial, he notes that none of them clearly describes the sponge-on-a-stick being used for personal hygiene, and that a more logical — not to mention less gross — explanation would be its use as a toilet brush.

So if the Romans didn’t clean themselves with the tersorium, what did they use? Having examined scraps of cloth in an ancient septic tank in Herculaneum (an ancient city preserved in Campania, Italy), environmental archaeologist Mark Robinson concluded that fabric scraps were likely used instead of a sponge. Another option was to use pottery shards, known as pessoi (Greek for “pebbles”). This may sound almost as bad as using a shared sponge, but these pottery pieces — which were readily available in ancient Rome — were specially selected, with smooth edges. 

The Romans likely had options when it came to bathroom hygiene — but whether that was in the form of a shared sponge-on-a-stick, scraps of fabric, shards of pottery, or a combination of all three (or more), it’s hard to know for certain. What we can say for sure is this: We should all be very grateful for toilet rolls and bidets.  

Armenia Was the First Country to Adopt Christianity as an Official Religion

Though modern-day Armenia did not achieve lasting independence until 1991, the country’s origins date back to around the year 2492 BCE according to Armenian mythology. In that year, an ancient Armenian warrior known as Hayk is believed to have defeated invading forces led by a Mesopotamia leader called Bel, which in turn saw what now encompasses modern-day Armenia fall under Hayk’s dominion. Many centuries later, Armenia made history by becoming the first country to adopt Christianity as its official state religion. Around the year 300 CE, an apostle named St. Gregory the Illuminator converted King Tiridates III of Armenia to Christianity, and it was made the official state religion in 301 CE. The newly formed Armenian Apostolic Church subverted the pagan ideology that once existed throughout the region, and it eventually became the country’s national church.

The First Recorded War Took Place in Present-Day Iran

The ancient kingdom of Elam, located in the southern region of modern-day Iran, contained settlements dating as far back as 7200 BCE. Millennia later, around the year 3200 BCE, the Proto-Elamite period began, marking the start of organized civilization throughout the region. Though few specifics are known about these early societies, what is known is that the region was the site of the first recorded war in human history. Around 2700 BCE, the Sumerian King Enmebaragesi led an attack against the Elamites, ultimately emerging victorious. Though there may have been conflicts before this, the battle — for which details are sparse — marks the earliest recorded account of a long-distance military campaign between opposing independent states.

The Oldest Surviving Anatomical Atlas Originated in China

In 1973, a seminal 2,200-year-old atlas of human anatomy written on ancient silk was discovered in south-central China, dating to the time of the Han dynasty (206 BCE to 220 CE) — making it the oldest surviving anatomical atlas ever discovered. Known as the Mawangdui medical manuscripts, these texts describe various “meridians” found throughout the human body, a term used to refer to arteries, blood vessels, and other internal elements. The Mawangdui texts also predate many other ancient Chinese texts related to acupuncture, suggesting that these early anatomical findings may have heavily influenced the science of acupuncture in the region. The artifact was uncovered in the tomb of a Han dynasty aristocrat named Xin Zhui (also known as Lady Dai), who was buried alongside copies of the medical texts in 168 BCE.

The First Dumps

As cities grew, some societies began to push waste farther away from the home. By about 500 BCE, the Athenians in ancient Greece had established what are often considered the first municipal dumps in the Mediterranean world. Laws required waste to be deposited at least a mile outside the city walls and banned throwing garbage into the streets.

Similar patterns appear elsewhere. In ancient Egypt, planned towns placed rubbish heaps beyond their walls, while in Mesopotamia and other regions, people concentrated refuse in designated pits, middens, and dumping grounds rather than scattering it.

But these systems were rarely tidy or consistent. Even in classical Athens and Rome — societies with laws governing sanitation — enforcement was uneven and waste still piled up in many areas. In Rome, property owners were responsible for cleaning the street in front of their homes, and while some recycling and scavenging took place, dumps outside the city grew steadily.

The Original Recyclers

Centuries before the “Reduce, Reuse, Recycle” slogan, many ancient societies routinely incorporated debris from everyday life — including broken pottery, ash, rubble, and organic waste — intro construction projects. Archaeologists have found that materials from demolished buildings and discarded goods were mixed into mud bricks, packed into earthen floors, or used as leveling fill.

In Pompeii, for example, large mounds of refuse outside the city walls were not simply trash heaps but staging areas. Materials such as plaster and ceramics were sorted and then brought back into the city to be reused in construction.

This kind of reuse was widespread and practical. Unlike today’s plastics-heavy garbage, ancient waste streams were dominated by organic and mineral materials — things that could be easily repurposed. Ash could stabilize surfaces, broken ceramics could be mixed into building materials to strengthen floors and walls, and even human and animal waste could be (and often was) used in agriculture as fertilizer or for dyeing and tanning.

From Trash to Ash

Another common strategy for ancient garbage disposal, in places such as the Andes and Mesoamerica, was burning. Fire reduced the volume of organic waste and helped control odors and pests. The resulting ash could then be reused: It was often spread over streets, incorporated into construction, or used in cleaning.

But burning trash wasn’t always purely practical. In many cultures, fire had ritual significance. Offerings to gods were often consumed in flames, transforming physical materials into smoke that rose skyward as messages to the heavens. In some cases, the line between disposal and ritual destruction blurred, with burning serving both functional and symbolic purposes.

The First Sewers

When human waste wasn’t just deposited nearby or collected for reuse, it was sometimes flushed away. About 4,000 years ago, the Minoans of Crete were among the first to dump their sewage into water. They developed remarkably advanced plumbing systems and what might be the first flush toilets. At the palace of Knossos, rainwater was collected and used to flush several toilets in the east wing, carrying sewage through ceramic pipes into underground channels. These systems even included manholes for maintenance — a strikingly modern touch.

In the Indus Valley, cities such as Mohenjo-daro and Harappa (both in modern-day Pakistan) built extensive drainage networks during their peak in the third millennium BCE. Houses had bathrooms and toilets connected to covered street drains, with carefully sloped channels and cesspits designed to prevent clogging. Wastewater flowed out of homes and into larger systems, helping to keep living spaces relatively clean.

Later, the Romans scaled these ideas up dramatically. The Cloaca Maxima, one of the earliest large sewer systems, carried enormous volumes of waste out of Rome and into the Tiber River. Public latrines and flowing water created a shared sanitation infrastructure — though not necessarily a hygienic one. These systems didn’t necessarily solve the problem so much as relocate it: Waste disappeared from sight and smell but often ended up contaminating water sources downstream.

Living With Waste — and On Top of It

Despite these varied strategies, one thing is clear: Ancient people lived much closer to their waste than most of us would tolerate today. Garbage accumulated in streets, between homes, and beneath floors. It was reused in buildings, dumped just beyond city walls, or flushed into nearby waterways. Even where sophisticated systems existed, they were limited by maintenance, scale, and an incomplete understanding of disease.

And yet, there is a crucial difference between ancient trash and modern waste. Most ancient refuse was biodegradable or inert. Food scraps decomposed, ash dispersed, and even broken ceramics eventually blended into the soil. That meant waste could be absorbed, repurposed, or transformed in ways that are far more difficult today.

In fact, many ancient cities were quite literally built from their own discarded past. Layer upon layer of debris became the ground beneath new construction — a process repeated across millennia. What began as refuse became real estate. It’s a reminder that trash has always been part of human life. What has changed is not the problem itself, but the materials we leave behind — and how long they stick around.
