765 CE

The Zenata Berber tribe of Banu Ifran rebels against the Abbasid Caliphate, and creates an independent state centered around Tlemcen (modern Algeria). Their tribal chief Abu Qurra rebuilds the city (formerly, the Roman colonia Pomaria). European writings make the first known mention of a three-field system in use in medieval Europe. The crop rotation is the practice of growing a series of different types of crops in the same area in sequential seasons. Under this system, the land of an estate or village is divided into three large fields, and makes a given section of land productive 2 years out of 3, instead of every other year (approximate date). King Pepin III ("the Short") restores the papal privileges (see Donation of Pepin) in Benevento and Tuscany territory (and partially in Spoleto).

In the 760s, the 8th century.
