to 68,000 Muslims and Croats. For the region of Sandžak, more than 5,000 victims are registered. About 300 villages and small towns were destroyed, along with a large number of mosques and Catholic churches. In 1946, Dragoljub Mihailović was convicted of crimes against humanity and high treason, and was executed with nine other Chetnik commanders. Background Interwar period During the interwar period in the Kingdom of Yugoslavia, veterans of Serbian guerilla units known as the Chetniks were split into different organizations, depending on their affiliation to the Democratic Party or the People's Radical Party. Organizations aligned to the Radical Party promoted the idea of a Greater Serbia. The leader of one such organization was Puniša Račić, who in 1928 killed two deputies of the Croatian Peasant Party (HSS) and mortally wounded its president, Stjepan Radić, in the Yugoslav Parliament. These organizations were dissolved following the imposition of royal dictatorship by King Alexander in 1929, and most of their members moved to the original "Chetnik Association for Freedom and Honor of the Fatherland" that continued to function. In 1932, Kosta Pećanac became the president of the Chetnik Association. As president, he transformed it into an aggressively partisan Serb political organisation and allowed entry to non-veterans. By 1938, the membership increased to around 500,000. Chetnik Association subcommittees were established throughout Bosnia and Herzegovina, particularly in eastern Bosnia, in territories they envisioned in a future expanded Serbia. Subcommittees were also formed in Croatia, mostly in areas inhabited by Serbs. They acted as semi-military organizations and were involved in violent activities throughout the 1930s, including murders. Croat and Slovene opposition to the Chetnik Association led to its prohibition in Banovinas with an ethnic Croat and Slovene majority. Some of its sections continued to operate in those regions in the following years, on a reduced scale. The Chetnik subcommittees and organizations with a similar program opposed the formation of the autonomous Banovina of Croatia, that was negotiated in August 1939 under the Cvetković–Maček Agreement by Croatian and Serbian political leaders. They called for the creation of the Banovina of Serbia, with parts of Bosnia and Herzegovina and the Dalmatian coast that were included in the Croatian Banovina. Headed by the Serbian Cultural Club group, a movement called "Serbs united" (Srbi na okup) was formed, which claimed that the position of Serbs in the Banovina of Croatia was endangered. Pro-Chetnik organizations were active in the movement's
