Yugoslavia was a country in Southeastern and Central Europe for most of the 20th century. It came into existence after World War I in 1918 under the name of the Kingdom of Serbs, Croats and Slovenes. It was renamed the Kingdom of Yugoslavia in 1929. During World War II, Yugoslavia was invaded by the Axis powers. After the war, the kingdom was abolished and replaced by a communist government led by Josip Broz Tito, who became president-for-life until his death in May 1980.
In mid-1991 and the years after, influenced by economic and political turmoil and nationalism, Yugoslavia was dissolved and split up into smaller countries: Bosnia and Herzegovina, Croatia, Kosovo, Macedonia, Montenegro, Serbia, and Slovenia. The breakup was accompanied by a series of ethnically-based conflicts known as the Yugoslav Wars, which were marred by many war crimes.
