The history of football in
Trbovlje dates back to 1922, when ŠK Zora was established. In the same year, the club aroused a lot of interest in this sport among youth working class. In 1924, the club was banned after a political clash with
Orjuna. Some former members then founded DSK Svoboda, which renamed as SK Amater in 1927. In 1972, on the 50th anniversary of the club, they won the
Slovenian Republic League for the first time. A successful period lasted until 1980, as Rudar won the Republic titles two more times between 1974 and 1979. They never returned to the first division. ==Honours==
