The Montreal Maroons hockey team was created to appeal to the anglophone neighborhoods of Montreal. On January 2, 1918, the Montreal Arena, shared by the Montreal Canadiens and the Montreal Wanderers, burnt down. The Canadiens, who drew primarily Montreal’s francophones, moved to the Jubilee Arena which, in 1919, also burnt down, before settling in the Mount Royal Arena, which had natural ice and seating for 3,250. The Wanderers, team of Montreal’s anglophone community, folded. By 1922, work began to build a team to appeal to the anglophones and return to the NHL. In July 1924, construction began on a new arena, on the site of a former roller-skating rink known as the Forum. By fall, at a cost of $1.5 million, the Montreal Forum was complete. The Montreal Forum was the first large arena in the NHL. The Maroons joined the NHL in 1924, along with the Boston Bruins. The Canadiens initially objected to a second team in Montreal, but relented when compensated by the expansion fee. The expansion fees for each team was $15,000. $11,000 of the Maroons’ fee went to their local rivals, the Canadiens. Their owner was unconcerned with having a second franchise in the same city; rather, he would later state, he “saw in them an important and lucrative local rivalry.”

The 1925 – 1926 NHL season was the ninth season of the National Hockey League (NHL). The NHL dropped the Hamilton, Ontario team and added two new teams in the United States of America (US), the New York Americans and the Pittsburgh Pirates to bring the total number of teams to seven. The Ottawa Senators were the regular-season champion, but lost in the NHL playoff final to the Montreal Maroons. The Maroons then defeated the defending Stanley Cup champion Victoria Cougars of the newly renamed Western Hockey League three games to one in a best-of-five series to win their first Stanley Cup.

The 1934 – 1935 NHL season was the 18th season of the National Hockey League (NHL). Nine teams each played 48 games. The Montreal Maroons were the Stanley Cup winners as they swept the Toronto Maple Leafs in three games in the final series.

The league allowed the Maroons to suspend operations for the 1938 – 1939 season. The Maroons’ owners tried to sell to interests in St. Louis, Missouri. Earlier in the decade, St. Louis proved that it could support NHL hockey when the Ottawa Senators moved there to become the Eagles. However, while the Eagles had drawn very well, they survived only one season, due to the high costs of traveling to Boston, Montreal, and Toronto (the Eagles had assumed the Senators’ place in the Canadian Division in defiance of geographic reality). The league was not about to give St. Louis another chance, given the economic situation of the time.

At the 1945 annual league meeting, held on September 7, it was noted that the backers of the Maroons franchise were in discussion to sell to a group from Philadelphia fronted by Canadiens board member Len Peto. The league governors were prepared to approve the transfer, provided the Philadelphia group could prove they had the necessary funds for a hockey team. They also made sure to clarify that the Maroons franchise rights would expire in April 1947 unless something were done with them.
