Count Roger II of Sicily is crowned the first king of Sicily.

Roger II or Roger the Great was King of Sicily and Africa, son of Roger I of Sicily and successor to his brother Simon. He began his rule as Count of Sicily in 1105, became Duke of Apulia and Calabria in 1127, then King of Sicily in 1130 and King of Africa in 1148.

The Kingdom of Sicily was a state that existed in Sicily and the southern Italian Peninsula as well as, for a time, in Northern Africa, from its founding by Roger II of Sicily in 1130 until 1816. It was a successor state of the County of Sicily, which had been founded in 1071 during the Norman conquest of the southern peninsula. The island was divided into three regions: Val di Mazara, Val Demone and Val di Noto.
