made a decision to administratively and politically merged the two separate Kingdoms of Naples & Sicily, which ended up forming the Kingdom of the Two Sicilies in 1816. In 1861, however, Sicily became part of the Kingdom of Italy as a result of the Risorgimento. Prior to the Risorgimento, the Two Sicilies were conquered by the Kingdom of Sardinia during the Expedition of the Thousand (led by general Giuseppe Garibaldi) in 1860, and subsequently brought under the monarchial realm of Sardinia. After the unification of Italy and the Fascist era, a wave of Sicilian nationalism led to the adoption of the Statute of Sicily, under which the island has become an autonomous region. Since 1946, the island enjoys the most advanced special status of all the autonomous regions. Demographics Sicily has experienced the presence of a number of different cultures and ethnicities in its vast history, including the aboriginal peoples of differing ethnolinguistic origins (Sicani, Siculi and Elymians), Bruttians, Morgetes, Oenotrians, Phoenicians and Carthaginians, Ancient Greeks (Magna Graecia), Mamertines, Romans and Jews during the ancient and classical periods. In the early medieval era, Sicily experienced the brief rule of Germanic Vandals and Iranic Alans during the Kingdom of the Vandals and Alans, while under Byzantine, Saracen and Norman rule, there were Byzantine Greeks, Arabs and Normans. From the late medieval period into the modern era, Aragonese, Spaniards and French ruled over and left a minor impact on the island, while Albanians settled and formed communities which still exist today known as the Arbereshe. About five million people live in Sicily, making it the fourth most populated region in Italy. However, in the first century after the Italian unification, Sicily had one of the most negative net migration rates among the regions of Italy because of millions of people moving to the Italian mainland and countries like Germany, Sweden, Belgium, the United States, Canada, Australia, Brazil, Argentina, the United Kingdom, France, New Zealand, Singapore and South Africa. Many Sicilian communities, including those formed by the descendants of the Sicilian migrants, are all over the world. It is estimated that the number of people of Sicilian descent in the world is more than six million. The most famous community is represented by the Sicilian Americans. Like the other parts of Southern Italy, immigration to the island is relatively low compared to other regions of Italy because workers tend to head to Northern
