Albania is a Balkan country in Southeast Europe, bordering Montenegro, Kosovo, North Macedonia, and Greece, with coastlines on the Adriatic and Ionian Seas. Its capital and largest city is Tirana. Albania has a predominantly Muslim population with a significant Christian minority and was a staunchly isolationist Stalinist state until its transition to democracy after 1990. Today, it is a parliamentary democracy, a member of NATO since 2009, and is focused on market-oriented economic development, with a diverse, mountainous landscape and a rich cultural heritage.
