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.
Boston Bruins
In their first-ever playoff run, the Bruins reached the Stanley Cup Final where they lost to the Ottawa Senators in the first Cup Final to be between exclusively NHL teams. In 1929 the Bruins defeated the New York Rangers to win their first Stanley Cup. Standout players on the first championship team included Shore, Harry Oliver, Dit Clapper, Dutch Gainor and goaltender Tiny Thompson. The 1928–29 season was the first played at Boston Garden, which Adams had built after guaranteeing his backers $500,000 in gate receipts over the next five years. The season after that, 1929–30, the Bruins posted the best-ever regular season winning percentage in the NHL (an astonishing .875, winning 38 out of 44 games, a record which still stands) and shattered numerous team scoring records, but lost to the Montreal Canadiens in the Cup Final.
