In the time of the final split (1054) much of the southern Italy was still under Byzantine rule and was organized as the Catepanate of Italy. For centuries, church life in Byzantine regions of Italy was developing under dual influence of Latin and Byzantine traditions. During the 11th century, Latin rite churches in Byzantine Italy still did not use the interpolated Nicene Creed (Filioque) and were in full communion with Eastern Orthodoxy. During the Byzantine–Norman wars, Byzantine Empire finally lost its last positions in the West. The Norman conquest of southern Italy was completed with the Conquest of Bari in 1071.
