The postwar settlement ended Greece's territorial expansion, which had begun in 1832. The 1947 Treaty of Paris required Italy to hand over the Dodecanese islands to Greece. These were the last majority-Greek-speaking areas to be united with the Greek state, apart from Cyprus which was a British possession until it became independent in 1960. Greece's ethnic homogeneity was increased by the postwar expulsion of 25,000 Albanians from Epirus (see Cham Albanians). The only significant remaining minorities are the Muslims in Western Thrace (about 100,000) and a small Slavic-speaking minority in the north. Greek nationalists continued to claim southern Albania (which they called Northern Epirus), home of a significant Greek population (about 3%-12% in the whole of Albania), and the Turkish-held islands of Imvros and Tenedos, where there were smaller Greek minorities.
