All of the following factors probably helped account for the increase in the European population between 1000 and 1300 except the monopolization of women by the elite. The dramatic increase in European population between 1000 and 1300 was primarily due to an increased birth rate outstripping high medieval mortality rates. Between the years 1000 and 1300 it is estimated that Europe's population doubled. It was a dynamic and remarkable period, Europe experienced one of the longest periods of sustained growth in human history. And this growth was crucial to the political/cultural achievements of this period.

The High Middle Ages (1000-1300) was marked as a period of intellectual flowering.
