After the war, Sarajevo was the capital of the Socialist Republic of Bosnia and Herzegovina within the Socialist Federal Republic of Yugoslavia. The Republic Government invested heavily in Sarajevo, building many new residential blocks in the municipalities of Novi Grad and Novo Sarajevo, while simultaneously developing the city's industry and transforming Sarajevo into a modern city. Sarajevo grew rapidly as it became an important regional industrial center in Yugoslavia. Between the end of the war and the end of Yugoslavia, the city grew from a population of 115,000 to more than 600,000 people. The Vraca Memorial Park, a monument for victims of World War II, was dedicated on 25 November, the "Statehood Day of Bosnia and Herzegovina" when the ZAVNOBIH held their first meeting in 1943.
