Before the Balkans Wars, Kosovo was part of the Paša of Albania. Afterwards, it became part of the Serbian Kingdom, even though more than 95% of the people living in it are ethnic Albanians. Kosovo became and autonomous republic in 1945, under Josip Broz Tito. The people of Kosovo didn't fight against Serbia during the Yugoslav Wars with Croatia and Bosnia, thereby splitting Serbia's forces. Instead, they decided to attack in 1999, and got crushed. Then, in 2008 they declared independence and issued their first passports.
During a protest, the American embassy was attacked, along with a local McDonald's.
