this all, the museum was funded by the Austro-Hungarian's departments of education and culture as well as by private donations and charity events led by the Museum Society. 1913–1991 With the opening of the museum in its new home in 1913 (where it still remains), its collections that varied from history, geography, archaeology (prehistoric, ancient and mediaeval), ethnology, history of art and natural history (biology, geology and mineralogy), and to some extent language, literature, statistics and bibliography, were divided into four buildings based on a new set of categories: Archaeology, Ethnology, Natural History, and the Library. Two years later in 1914, as World War I began, the museum suspended its operations. After the end of the war in 1918, which was followed by the first union of the South Slavs, the museum resumed its operations under the administration of what was then called the Kingdom of Serbs, Croats and Slovenes, which was later known as Yugoslavia. Under this administration, which lasted during the interwar years of 1918–45, a hegemonic centralized administration was developed in which the judicial branch of government along with the Serbian bourgeoisie, paid very little economic and cultural attention to Bosnia and Herzegovina. This led to an abrupt socio-economic, political and cultural decay in Sarajevo as it found itself in the margins of the Kingdom. The National Museum thus lost much of its funding and clout and was beginning to lose its ability to maintain and archive its artifacts. As World War II approached in 1941 (and lasted until 1945), the National Museum's troubles further developed as its opportunities to operate diminished. It was during this war-time period that the National Museum experienced the least activity and development. After World War II, under a Socialist Yugoslavia, the National Museum made slow progress until the early part of the 1960s. Culture was declared to be of special importance for society by the Socialist Government and this period in time marked some of the National Museum's highest achievements in scientific research and publishing activities and exhibitions. (See the publications) During this period, was significant the contribution of Museum's Natural departments in the development of the Movement “Science to Youth" – Alliance of Young Researchers of Bosnia and Herzegovina. War years 1992–1995 The War in Bosnia and Herzegovina in 1992–95 not only ended the prolific activity of the National Museum, but it directly caused structural damage to the building. During
