Bosnia and Herzegovina
The first state in modern-day Bosnia and Herzegovina was in the Middle Ages. During the Ottoman Empire, it was a very important province in the Balkans and the capital, Sarajevo, had 100,000 people. In the Russo-Turkish War (1877–1878), Austria-Hungary occupied Bosnia and Herzegovina and annexed it in 1908. In 1914 the Archduke Ferdinand and his wife, Sophie, were assassinated in Sarajevo, leading to World War I. From 1918 until 1992, the country was a part of Yugoslavia. After a 3-year long war, part of the Yugoslav Wars, Bosnia and Herzegovina proclaimed independence as a country consisting mostly of Serbs, Croats and Bosnian Muslims.
