County of Apulia and Calabria

The County of Apulia and Calabria (Latin: Comitatus Apuliae et Calabriae), later the Duchy of Apulia and Calabria (Latin: Ducatus Apuliae et Calabriae), was a Norman state founded by William of Hauteville in 1043, composed of the territories of Gargano, Capitanata, Apulia, Vulture, and most of Campania. It became a duchy when Robert Guiscard was raised to the rank of duke by Pope Nicholas II in 1059.
