The Cleveland Crusaders played in the World Hockey Association from 1972 to 1976. In their first two seasons they played at the old Cleveland Arena before moving to the Richfield Coliseum in 1974. They relocated to Minnesota when hockey's California Golden Seals moved to town to become the Cleveland Barons.
