After that era, the Ottoman Empire was on the rise. It headed towards the Balkans, which due to cultural diffusion introduced new culture and ways of life to that area. The Turkish defeated the Serbians at the great battle of Kosovo in 1389. They later conquered Bosnia and Herzegovina in 1463. They spread the teachings of Muhammad the prophet and Muslim ways in that area. Jewish people also flooded into the area of Sarajevo (the capital). As parts of the Ottoman borders shrank, Bosnia-occupied parts shrank apart. Some countries next to Bosnia fought for their land, like Serbia and Montenegro. At the Berlin Congress in 1878, after the Russo-Turkish War, Austria-Hungary was given the rights to occupy and govern Bosnia and Herzegovina. Bosnia was still with the Ottoman Empire and Austria-Hungary annexed them. This brought them into a feud with the Serbs and caused one Serb nationalist to assassinate the Austrian Archduke Franz Ferdinand in Sarajevo on June 18, 1914. This assassination was one of the causes of World War I. Bosnia and Herzegovina was annexed to Serbia. The newly formed kingdom was called Kingdom of the Serbs, Croats, and Slovenes. Later it changed to Yugoslavia.
