An engagement is a promise to marry, and also refers to the time between proposal and marriage. During this period, a couple is said to be affianced, engaged to be married, or simply engaged.

The engagement period

The concept of an engagement period may have begun in 1215 at the Fourth Lateran Council, headed by Pope Innocent III, which decreed that "marriages are to be ... announced publicly in the churches by the priests during a suitable and fixed time, so that if legitimate impediments exist, they may be made known." Such a formal church announcement of the intent to marry is known as banns. In some jurisdictions, reading the banns may be part of one type of legal marriage.

Engagement rituals vary widely by culture. In in the Western provinces of India, a gosling is the traditional betrothal gift. In twelfth century China, the woman was expected to produce a suitable gift for the man within one week of the proposal, or the wedding could be invalidated. In the late nineteenth century, Cajun betrothals were initiated when the man placed a small piece of ice on the foot of his beloved.

The modern Western form of the practice of giving or exchanging engagement rings is traditionally thought to have begun in 1477 when Maximilian I, Holy Roman Emperor, gave Mary of Burgundy a diamond ring as an engagement present. However, engagement rituals vary widely by culture.

Engagement parties

Some, but not all, engagements are honored with an engagement party, often hosted by the bride's parents. It may be formal or informal, and is typically held between six months and a year before the wedding. Traditionally, engagement parties allowed the bride's parents to announce the impending marriage to friends and families. Today, such an event can either be an announcement or simply a celebration.

Fiancé(e)

A man who is engaged to be married is called his partner's fiancé; a woman similarly engaged is called her partner's fiancée. These words are pronounced identically in English; the separate feminine form exists because of the inflectional morphology of grammatical gender in French, where the term originated.

Proposal

main: Proposal of marriage The classic proposal position is 'down on one knee' shown in the picture to the right. Engagement is most often initiated by a proposal of marriage, or simply a proposal. The proposal often has a ritual quality, involving the presentation of the engagement ring and a formalized asking of a question such as "Will you marry me?" In a heterosexual relationship, the man traditionally proposes to the woman, but this is no longer universal. February 29th is said to be the one day (coming round only once every four years) when a woman can propose to her partner.
