The NHL's American Division was formed after expansion in 1926. The division existed for 12 seasons until 1938. During its run as a separate division, the American Division was the slightly more successful of the league's two divisions. American Division teams won seven Stanley Cup championships compared with five won by the Canadian Division and contested three intra-divisional Finals under the cross-over playoff format then in use, compared to only one such Finals between two Canadian Division teams.
