Donated in 1892 by Lord Stanley of Preston, the Governor General of Canada, the Stanley Cup was originally awarded to the top amateur team in Canada, who would then accept challenges from the winners of other leagues. From its inception until 1912, the Cup was nearly always won by teams from Montreal, Winnipeg, and Ottawa. In 1903 Ottawa won the Cup, after finishing the season tied for first in the Canadian Amateur Hockey League with the Montreal Victorias. They played a two-game, total-goal series for the league championship. The Montreal Hockey Club, who had held the Cup, finished third in the league and therefore lost the right to keep it.
Stanley Cup Finals
After the NHL became the last remaining league to compete for the Cup, the trophy was then awarded to the winner of the NHL's championship playoff round. This first took place in 1927 between the Boston Bruins and the Ottawa Senators, which was planned to be a best-of-three series, although the series allowed ties. The series ended after four games, when the Senators defeated the Bruins in the fourth game.
