Football club Hapoel Jerusalem was founded in 1926. The team belonged to the "Histadrut", Israel's organization of workers unions, and represented Socialist values. In 1957, the team advanced for the first time to the top Israeli league. Throughout the 1960s and 1970s, the years known as the "golden era" of the team, " Hapoel" outperformed and outnumbered in spectators city rivals Beitar Jerusalem – a team associated with the right-leaning "revisionist" movement. The most important achievement in the history of the club was winning the Israel State Cup in 1973.
