The 1926–27 NHL season was the tenth season of the National Hockey League. Ten teams played 44 games each. The success of the Boston Bruins and the Pittsburgh Pirates led the NHL to further expand to the United States. On May 4, 1926, the Western Hockey League, unable to match the higher salaries being offered by the NHL, folded, with many of its assets sold to the NHL. In particular, the NHL Board of Governors had purchased the contracts of every player in the WHL for $258,000. The entire rosters of two WHL teams, the Portland Rosebuds and Victoria Cougars, were bought, respectively, by the expansion Chicago Black Hawks and Detroit Cougars. The league also added the New York Rangers to the fold. This left the NHL in sole possession of hockey's greatest players, as well as sole control of hockey's greatest trophy, the Stanley Cup, which was won by the Ottawa Senators.
