Which team won the first Stanley Cup after the NHL took full control of the trophy in 1926?

The Ottawa Senators won the first Stanley Cup awarded after the NHL took sole control of the trophy in 1926. They captured the 1927 Stanley Cup at the end of the 1926–27 NHL season.

The change followed the collapse of the Western Hockey League, which left the NHL as the only league controlling the sport’s top professional players and the Stanley Cup. Ottawa finished first in the Canadian Division and advanced through the playoffs as the NHL champion.

In the final, the Senators defeated the Boston Bruins in a best-of-five series, winning two games and tying two others. The original Senators won the Cup for the fourth time in seven years and their 11th time overall, counting championships before the NHL era. This was also the franchise’s final Stanley Cup.
