The main Tunisian cities were conquered by the Normans of Sicily under the Kingdom of Africa in the 12th century, but following the conquest of Tunisia in 1159–1160 by the Almohads the Normans were evacuated to Sicily. Communities of Tunisian Christians would still exist in Nefzaoua up to the 14th century. The Almohads initially ruled over Tunisia through a governor, usually a near relative of the Caliph. Despite the prestige of the new masters, the country was still unruly, with continuous rioting and fighting between the townsfolk and wandering Arabs and Turks, the latter being subjects of the Muslim Armenian adventurer Karakush. Also, Tunisia was occupied by Ayyubids between 1182 and 1183 and again between 1184 and 1187.
