Šajkaši were a specific river marine infantry of the Habsburg army, which moved in narrow, long boats, known as "šajka".

After 1400, the majority of the people in Šajkaška were Serbs who had settled the area before or after the Ottomans conquered the Balkan lands to the south .

After 1526 and the Battle of Mohacs, they moved to the northern Danube and to the city of Komarno which, for a long time, was the administrative headquarters of the Šajkaš forces.

In the beginning of the Habsburg administration, the population of the region was composed entirely of Serbs, which were brave and skillful warriors.

From 1941 to 1944, the region was occupied by the Axis Powers, and was attached to the Bács-Bodrog County of Horthy's Hungary.

In the 1942 raid, the Hungarian occupational authorities killed numerous ethnic Serbs, Jews and Romani in Šajkaška.

In 1944, the Soviet Red Army and Yugoslav Partisans expelled the Axis forces from the region, and Šajkaška became part of the Autonomous Province of Vojvodina within the new Socialist Yugoslavia.
