Girls were usually married off as soon as they reached puberty or sometimes even prior to that

Age of Consent throughout history has usually coincided with the age of puberty although at sometimes it has been as early as seven. Early on age of consent was a familial or tribal matter and only became a legal one in the Greco-Roman period. The Roman tradition served as the base for Christian Europe as well as the Christian Church itself which generally, essentially based upon biological development, set it at 12 or 14 but continued to set the absolute minimum at seven.

Viking women married young—as early as 12 years old. By the age of 20, virtually all men and women were married.
