The average age women got married in the 1700s was around 22, although this was a shift from earlier decades where the age was often younger.
During the 18th century, the traditional practice of arranged marriages based on parental wishes began to decline. A shift occurred towards marrying based on personal affection and choice. This societal change likely contributed to a slightly older average age for women getting married. While younger marriages still occurred, the rising influence of personal preference allowed women to delay marriage until they found a suitable partner they genuinely cared for. Therefore, while some women married quite young, the prevailing trend shifted towards later marriages compared to previous eras.
