American Hockey Association (1926-1942)

The American Hockey Association (AHA) was a minor professional hockey league that operated between 1926 and 1942. It had previously operated as the Central Hockey League (1925–1926), and before that as part of the United States Amateur Hockey Association. The founding president was Alvin Warren, who also owned the St. Paul Saints.

Other founding owners included William Grant, league secretary and owner of the Duluth Hornets (and Warren's successor as president in 1930), Paul Loudon of the Minneapolis Millers, and William Holmes, owner of the league's only Canadian franchise, the Winnipeg Maroons, and also owner of the Winnipeg Auditorium.

Eddie Livingstone, banished by National Hockey League team owners in 1917, owned the Chicago Cardinals. Eager to sign a new interleague agreement with the NHL in 1927, the AHA revoked Livingstone's franchise after one season when NHL president Frank Calder threatened that no deal would be signed with the league as long as it was associated with Livingstone.

The AHA was the first professional hockey league to field teams in the Southern United States. The Oklahoma-based Tulsa Oilers and Missouri-based St. Louis Flyers took the ice in 1928, predating the NHL's short-lived St. Louis Eagles franchise by six years. The Kansas City Greyhounds were added to the league in 1933. The Oilers and Flyers were also joined in the early 1940s by two Texas-based teams, the Dallas Texans and Fort Worth Rangers.

By 1930, some AHA owners, led by Walter Whiteside of the Tulsa Oilers, were questioning the league's relationship with the NHL. They approved the creation of a new Chicago franchise, the Chicago Shamrocks, owned by James E. Norris, bringing the league into an NHL market. Renaming the league the American Hockey League, they also established a franchise in Buffalo, New York, an IHL city, which would have been prohibited under the previous agreement with the NHL. In October 1930, Calder declared the AHL to be an outlaw league and threatened never to allow any AHL players into the NHL. The NHL carried out its threat and denied the applications of former AHL players to join NHL teams for the 1931–32 season. In the fall of 1931, the AHL applied to the Stanley Cup trustees to challenge for the trophy, but was unsuccessful in its attempts to force the NHL into a series.
