The First Marriage Contracts
Did you know that for centuries, marriage was more a legal contract than a romantic act? The first formal marriage records appeared in Mesopotamia, about 4,000 years ago. Civilizations like the Sumerians and Babylonians used clay tablets to register all details of the marriage: rights, duties, and even the bride’s dowry.
These contracts detailed who would manage the household, how assets would be divided, and what compensations would apply in case of divorce. The purpose was to protect the family, secure political alliances, and organize inheritance — showing that marriage back then was more strategic than emotional.
Interestingly, romantic love only became a central reason for marriage many centuries later, especially in medieval Europe, when new ideas about personal feelings and freedom of choice emerged.
Looking at these ancient tablets today, we can see that marriage has always involved a balance between affection and responsibility, revealing that even thousands of years ago, human relationships required clear rules and legal protection — and love, although present, was not always the main protagonist.
For much of Antiquity and the Middle Ages
For much of Antiquity and the Middle Ages, romantic love was not the main reason for marriage. Civilizations such as the Sumerians, Egyptians, Greeks, and Romans treated marriage as a strategic decision: to secure family alliances, protect property, and maintain social stability. In medieval Europe, especially among nobles and royalty, marrying for love was rare; marriages were arranged by families, and affection was often just a bonus.
It was only from the 18th century onwards, with cultural changes and the rise of literary romances, that romantic love began influencing the choice of partner. Before that, marriage was more of a social contract than an act of passion.
Interestingly, even when love did not dictate marriage, it already existed: the oldest recorded love letter dates back to around 2000 B.C. in Mesopotamia. Written on a clay tablet, it contains passionate verses dedicated to a woman, showing that human feelings have always been present, even in societies governed by strict rules.
These facts reveal that although marriage was structured and strategic, love was always there, quietly expressed through words and gestures.

The Science of Love
Love is not just a feeling; it has a chemical basis in the brain. The most famous hormone associated with love is oxytocin, often called the “love hormone.” It is released during closeness, hugging, affection, and intimacy, strengthening emotional bonds and creating feelings of trust and attachment.
But how long does it take for the brain to fall in love? Studies show that intense attraction can begin in just a few minutes, with immediate physical and emotional responses, while deep, lasting attachment develops over weeks or months, as oxytocin, dopamine, and serotonin interact.
Speaking of dopamine, love activates the same areas of the brain as substances like cocaine and other stimulants. This explains why being in love creates euphoria, energy, and intense focus on the loved one, similar to the chemical effects of dopamine-releasing drugs — proving that passion is literally pure chemistry.
In short, love combines hormones, neurotransmitters, and brain reactions that make the emotional experience tangible and measurable, showing how deeply our hearts and brains are connected when it comes to passion and bonding.
