The age of marriage was typically younger in the past, but the exact details depend place and time and the situation of the person. In Europe in the Middle Ages, for example, nobility typically married very young for modern standards, but that wasn't always the case among the peasants. A father didn't want to marry his daughter off to someone who didn't have anything, which was usually the case for poor peasant men. The man would have no means to support his wife and provide for the family. So typically the young men would wait until they had some land and a house before marrying, allowing them to support a wife and children. This typically would happen when they were 25-30 years old. Their wives, on the other hand, would typically be in the 15-20 age range. If the man's family was fairly wealthy and the prospective bride's family was fairly certain their daughter would be able to be supported by the man in the future, then the man would be able to get married before the age of 20. History is pretty interesting.
