A number of wars between the Normans and the Byzantine Empire were fought from c. 1040 until 1185 when the last Norman invasion of Byzantine territory was defeated. At the end of the conflict, neither the Normans nor the Byzantines could boast much power; by the mid-13th century exhaustive fighting with other powers had undermined the rule of both, leading to the Byzantines losing Asia Minor to the Turks in the 14th century, and the Normans losing Sicily to the Hohenstaufen, who in turn were succeeded by the Angevins and finally the Aragonese.
