The legal weight of a promise: why engagement was once a binding contract
Today, breaking an engagement is often a personal heartbreak. Historically, it was a legal crisis. From Roman oaths to medieval canon law, the period between proposal and wedding was a high-stakes transition of status, often carrying the same weight as marriage itself.
The modern concept of a 'semi-binding' engagement has deep roots in religious and civil law. In ancient Jewish practice, marriage was divided into two distinct stages: erusin (betrothal) and nissu'in (the marriage ceremony). During the Talmudic era (c. 1st century BC – 6th century AD), these ceremonies could be separated by up to a year, fundamentally changing the couple's interpersonal status during the interim [S1:p4, S1:p20]. Similarly, in Roman Catholic tradition, a formal betrothal was considered as binding as marriage, requiring a formal divorce to terminate [S1:pe22].
The legal implications of these vows were often severe. In medieval Europe, exchanging vows in the future tense—'I will take you'—constituted a betrothal, but sexual intercourse could transform that promise into a binding marriage [S1:p14]. The stakes were high enough that Richard III of England saw his brother's children declared illegitimate because the father was already betrothed to another woman [S1:p14]. In some common law jurisdictions, such as parts of the US and England, the 'spurned' partner could even sue for 'breaching promise' or 'heart-balm' [S1:p19].
Even the symbols we use today carry ancient biological myths. The tradition of wearing a ring on the fourth finger stems from the Roman belief in the 'vena amoris,' a vein believed to lead directly to the heart [S1:p35]. While the modern Western custom of the diamond engagement ring is often attributed to Holy Roman Emperor Maximilian I gifting a diamond to Mary of Burgundy in 1477, the practice of using rings to signify commitment dates back much further to the Hebrew Bible and the Byzantine Empire [S1:p33, S1:p34, S1:p36].
