After World War I and in the atmosphere of postwar chaos and raising anarchy, the Hungarian National Council in Nitra decided to negotiate with the Czechoslovak Army, pushing out Hungarian military forces and police from the territory of present Slovakia. The Hungarian National Council and the Town Council needed the Czechoslovak Army to restore public order, but hoped that situation was only temporary and formally protested against the "occupation" on 10 December 1918. However, the town became a part of Czechoslovakia. Nitra continued to be the seat of the Nitra county, until it was dissolved in 1928. In 1933, Nitra played an important role in the Slovak autonomist movement when the Pribina's Celebration (the anniversary of the consecration of the first Christian church) turned to the largest demonstration against Czechoslovakism.
