Ибн аль-Асир
The Norman Robert Guiscard, son of Tancred, invaded Sicily in 1060. The island was split between three Arab emirs, and the Christian population in many parts of the island rose up against the ruling Muslims. One year later, Messina fell, and in 1072 Palermo was taken by the Normans. The loss of the cities, each with a splendid harbor, dealt a severe blow to Muslim power on the island. Eventually all of Sicily was taken. In 1091, Noto in the southern tip of Sicily and the island of Malta, the last Arab strongholds, fell to the Christians. Islamic authors noted the tolerance of the Norman kings of Sicily. Ali ibn al-Athir wrote: "They [the Muslims] were treated kindly, and they were protected, even against the Franks. Because of that, they had great love for King Roger."
