True development of the region came after the Ottoman conquest when local Muslim noble Isa-Beg Isaković established the roots of the modern city of Sarajevo, between 1461 and 1463. The region grew along with the city, which quickly, after Istanbul, became the most important in the Balkans. Later rule by Austria-Hungary modernized and westernized the region. Under Yugoslavia, there was major development of the area, which more than tripled in size. Because of its ideal geographical location in between mountains, Sarajevo was chosen to host the 1984 Winter Olympics. Much of this progress was offset however by the Yugoslav Wars in the early 1990s.
