such it was the only example of military regime in occupied Europe. The Military Committee of the Provincial Committee of the Communist Party for Serbia was formed in mid-May 1941. The Central Committee of the Communist Party of Yugoslavia arrived in Belgrade in late May, and this was of great importance for the development of the resistance in Yugoslavia. After their arrival, the Central Committee held conferences with local party officials. The decision for preparing the struggle in Serbia issued on June 23, 1941 at the meeting of the Provincial Committee for Serbia. On July 5, a Communist Party proclamation appeared that called upon the Serbian people to struggle against the invaders. Western Serbia was chosen as the base of the uprising, which later spread to other parts of Serbia. A short-lived republic was created in the liberated west, the first liberated territory in Europe.

Services Aside from ground forces, the Yugoslav Partisans were the only resistance movement in occupied Europe to employ significant air and naval forces. Partisan Navy Naval forces of the resistance were formed as early as 19 September 1942, when Partisans in Dalmatia formed their first naval unit made of fishing boats, which gradually
