The modern Republic became independent after the collapse of the Ottoman Empire in Europe following the Balkan Wars. Albania declared independence in 1912 (to be recognised in 1913), becoming a Principality, Republic, and Kingdom until being invaded by Italy in 1939, which formed Greater Albania, which in turn became a Nazi German protectorate in 1943. In 1944, a socialist People's Republic was established under the leadership of Enver Hoxha and the Party of Labour. In 1991, the Socialist Republic was dissolved and the Republic of Albania was established.Albania is a parliamentary democracy. As of 2011, the capital, Tirana, was home to 421,286 of the country's 2,831,741 people within the city limits, 763,634 in the metropolitan area. Tirana is also the financial capital of the country. Free-market reforms have opened the country to foreign investment, especially in the development of energy and transportation infrastructure.
