Largely agricultural, Albania is one of the poorest countries in Europe. A battlefield in World War I, after the war it became a republic in which a conservative Muslim landlord, Ahmed Zogu, proclaimed himself president in 1925 and king (Zog I) in 1928. He ruled until Italy annexed Albania in 1939. Communist guerrillas under Enver Hoxha seized power in 1944, near the end of World War II. Hoxha was a devotee of Stalin, emulating the Soviet leader's repressive tactics, imprisoning or executing landowners and others who did not conform to the socialist ideal. Hoxha eventually broke with Soviet communism in 1961 because of differences with Khrushchev and then aligned himself with Chinese communism, which he also abandoned in 1978 after the death of Mao. From then on Albania went its own way to forge its individual version of the socialist state and became one of the most isolated—and economically underdeveloped—countries in the world. Hoxha was succeeded by Ramiz Alia in 1982.
