Greeks and Jews in Sicily
As for the Jews of Sicily, their communities remained relatively undisturbed since Arab rule in the 9th century. Similarly to the Italians living on the island, Sicilian Jews lived within their respective communities and had an emphasis on trade throughout the Mediterranean. While there are no evidence of independent Jewish city-states, Jewish regions of Sicily acted relatively autonomous in regards to trade similarly to Italian city-states across the Italian Peninsula, as long as they paid taxes on goods and the jizyah. The impact of trade from Jewish communities helped the Normans by providing an even bigger economic web for them to trade goods and acquire capital. These economic contributions were a big part of the wealth and success of the Norman Kingdom of Sicily.
