Love it?

Few moments in a person’s life are as emotional — and possibly as nerve-racking — as a marriage proposal. These proposals tend to be instantly recognizable, with a suitor dropping to one knee, ring in hand, to ask perhaps the most important question of their life: “Will you marry me?” 

It’s a tradition observed across much of the Western world, and one depicted in countless paintings, photos, films, and social media posts. But where does the customary kneeling gesture come from? We could, after all, be doing all manner of actions: standing with our arms out wide, bowing theatrically, or spinning on our heads in an act of wild virility. Let’s journey back through the centuries to find out when kneeling first became a common act, and how it attached itself to the art of proposing marriage.

Bending the Knee 

To understand the act of kneeling before someone, whether with amorous intentions or otherwise, we first need to look at the history of genuflection. The verb “genuflect” comes from the Latin genūflectĕre, in which genū means “knee” and flectĕre “to bend.” And bending the knee was popular long before Game of Thrones introduced the expression to a modern audience. 

It’s impossible to say exactly when it became commonplace, but we know that Alexander the Great adopted the Persian custom of proskynesis (genuflection) as part of his court etiquette sometime around 327 BCE. In other words, kneeling has been a custom for a very long time, as a way to show deference to someone — typically a person of higher status.  

Fast-forward to medieval Europe: By the Middle Ages, kneeling had become a deeply meaningful act embedded in both the social and religious customs of everyday life. Genuflecting was a well-established practice in the Catholic faith, in which people would kneel to pray, specifically on the right knee. This practice continues today: According to the General Instruction of the Roman Missal, a governing document published in 1969, “a genuflection, made by bending the right knee to the ground, signifies adoration, and therefore it is reserved for the Most Blessed Sacrament.” 

Knights and vassals also kneeled before lords, kings, and queens as a formal gesture of loyalty, obedience, and submission. Typically, a person would kneel on the left knee while swearing loyalty or service to a monarch, noble, or anyone of superior rank; the right knee was reserved for religious genuflection. The main exception to this custom was (and still is) the tradition of British knighting ceremonies, in which the knight-elect kneels on their right knee in front of the king or queen to receive their knighthood.
