Norman–Arab–Byzantine culture

The term Norman–Arab–Byzantine culture, Norman–Sicilian culture or, less inclusively, Norman–Arab culture (sometimes the "Arab–Norman civilization"), refers to the interaction of the Norman, Byzantine Greek, Latin, and Arab cultures following the Norman conquest of the former Emirate of Sicily and North Africa from 1061 to around 1250. The civilization resulted from numerous exchanges in the cultural and scientific fields, based on the tolerance shown by the Normans towards the Latin- and Greek-speaking Christian populations and the former Arab Muslim settlers. As a result, Sicily under the Normans became a crossroad for the interaction between the Norman and Latin Catholic, Byzantine–Orthodox, and Arab–Islamic cultures.

Norman conquest of southern Italy

The first Normans arrived in Southern Italy during the High Middle Ages, between the years 1000 and 1030. The de Hautevilles had enjoyed a mutually beneficial relationship with the papacy in the period leading up to their arrival in Southern Italy, with the Church recognizing them as legitimate lords in return for their military allegiance. The Normans would seize upon divisions between the Lombards and Byzantines in the region in order to establish a foothold, and they would establish a capital at Aversa in 1030. A defining victory for the Normans would come in 1053, when they defeated a papal force constituted of Lombards and imperial Byzantine forces at Civitella sul Fortore. The battle would see them also capture Pope Leo IX, who had been backing the force opposing them. Robert Guiscard would mount later campaigns after his conquest of Sicily to further Norman influence in Southern Italy, notably capturing Bari in 1071 and Salerno in 1077.

Norman conquest of Sicily

Seventy-three years after the Islamic invasion of Southern Italy, the Byzantine forces began a reconquest of Sicily under the Byzantine general George Maniakes in 1038.
