From 1923 until 1941 in Blato are operated by two football clubs. In those years were often apart and create new clubs, and one of the reasons were the political conditions that are often changed in these turbulent inter-war years. So the BŠK Zmaj in early 1929 was banned by the government. As Zmaj was very popular in Blato because the period from 1926 to 1928 had not recorded a single defeat of the then rivals, and his name and what he represented could not be stifled by the authorities. Thus, in 1937 by people who were not involved in the clubs back then launched an initiative to establish the Zmaj and he is revived by the arrival of the Italian occupiers in 1941.
