婚约起源于古代社会的买卖婚姻，近现代多数国家或地区亲属法也规定了婚约制度。

Affiance originated from mercenary marriage of ancient society. The relative law of most countries or regions also stipulate the affiance system.

这一观念确立于早期父权制文化，那时女人和小孩被看作财产，女孩在青春早期就被买卖婚姻交易。

This concept was established in early patriarchal cultures when women and children were considered property, and girls were sold into marriage in their early teens.
