12th century

As a means of recording the passage of time, the 12th century was that century which lasted from 1101 to 1200. In the history of European culture, this period is considered part of the High Middle Ages and is sometimes called the Age of the Cistercians. In Song Dynasty China an invasion by Jurchens causes a political schism of north and south. The Khmer Empire of Cambodia flourished during this century, while the Fatimids of Egypt were overtaken by the Ayyubid dynasty. See also: Renaissance of the 12th century
