North American Hockey League (1973–1977)

The North American Hockey League (NAHL) was a professional minor league ice hockey league that operated in the Northeastern United States and Quebec, Canada, from 1973 to 1977. Formed as a successor to the Eastern Hockey League, the NAHL aimed to provide a higher level of competition and attract more fans with a mix of established veterans and up-and-coming players.

The league consisted of teams primarily located in smaller cities that often had a strong local hockey following. Franchises included the Philadelphia Firebirds, Johnstown Jets, Syracuse Blazers, Mohawk Valley Comets, Broome Dusters, and Quebec Nordiques (prior to their entry into the World Hockey Association).

The NAHL was known for its rough and physical style of play, earning it the moniker "the tough league." Several players who later achieved success in the National Hockey League (NHL) honed their skills in the NAHL.

Financial difficulties and competition from the World Hockey Association (WHA) contributed to the league's demise after only four seasons. The NAHL folded following the 1976-77 season. Despite its short lifespan, the NAHL left a lasting impact on hockey in the region and contributed to the development of future NHL talent. The movie Slap Shot drew inspiration from the rowdy, working-class culture that defined the league.
