In the 1920s, Fascist Italy pursued an aggressive foreign policy that included an attack on the Greek island of Corfu, aims to expand Italian territory in the Balkans, plans to wage war against Turkey and Yugoslavia, attempts to bring Yugoslavia into civil war by supporting Croat and Macedonian separatists to legitimize Italian intervention, and making Albania a "de facto" protectorate of Italy (which was achieved through diplomatic means by 1927). In response to revolt in the Italian colony of Libya, Fascist Italy abandoned the previous liberal-era colonial policy of cooperation with local leaders. Instead, claiming that Italians were a superior race to African races and thereby had the right to colonize the "inferior" Africans, it sought to settle 10 to 15 million Italians in Libya. This resulted in an aggressive military campaign against the Libyans, including mass killings, the use of concentration camps and the forced starvation of thousands of people. Italian authorities committed ethnic cleansing by forcibly expelling 100,000 Bedouin Cyrenaicans, half the population of Cyrenaica in Libya, from land that was slated to be given to Italian settlers.
