TheItalo-Normans (Italian:Italo-Normanni), orSiculo-Normans (Siculo-Normanni) when referring toSicily andSouthern Italy, are theItalian-born descendants of the firstNorman conquerors to travel to Southern Italy in the first half of the eleventh century. While maintaining much of their distinctlyNorman piety and customs of war, they were shaped by the diversity of Southern Italy, by the cultures and customs of theGreeks,Lombards, andArabs in Sicily.

Normans first arrived in Italy as pilgrims, probably on their way to or returning from eitherRome orJerusalem, or from visiting the shrine atMonte Gargano, during the late tenth and early eleventh centuries. In 1017, the Lombard lords inApulia recruited their assistance against the dwindling power of the ByzantineCatapanate of Italy. They soon established vassal states of their own^[1] and began to expand their conquests until they were encroaching on the Lombardprincipalities of Benevento andCapua,Saracen-controlled territories, as well as Greek, and territory underpapal allegiance. Their conquest of Sicily, which began in 1061, was completed by 1091.

Italo-Normans were the primary Norman mercenaries in the employ of theByzantine emperors, and many found service inRome under the pope. Some went toSpain to join theReconquista, and in 1096 the Normans ofBohemond of Taranto joined theFirst Crusade and set up theprincipality of Antioch in theLevant.

In 1130 underRoger II, they created theKingdom of Sicily, encompassing the whole of their conquests on the peninsula and the island. Between 1135 and 1155 Roger II also created an Italo-NormanKingdom of Africa in coastalTunisia andTripolitania. He intended to unite this African kingdom with his Kingdom of Sicily, but his untimely death in 1154 put an end to these plans.

When founded in 1130, this Italo-Norman kingdom united the whole of Southern Italy under the same rule for the first time since Justinian's brief reconquest of the peninsula as a whole. The Norman dynasty established byRoger II continued withWilliam I, and thenWilliam II. After the latter's death without heirs in 1189, and following the brief reign of his illegitimate cousinTancred of Lecce, the German EmperorHenry VI ofSwabia (who had marriedConstance, aunt and legitimate successor of William II) conquered the kingdom in 1194, defeatingWilliam III of Sicily (son of Tancred) and ending the Italo-Norman dynasty.
