In which country was the contemporary sport of ice hockey developed?

Ice hockey is a contact team sport played on ice, usually in a rink, in which two teams of skaters use their sticks to shoot a vulcanized rubber puck into their opponent's net to score goals. The sport is known to be fast-paced and physical, with teams usually fielding six players at a time: one goaltender, and five players who skate the span of the ice trying to control the puck and score goals against the opposing team.

Ice hockey is most popular in Canada, central and eastern Europe, the Nordic countries, Russia, and the United States. Ice hockey is the official national winter sport of Canada.

The contemporary sport of ice hockey was developed in Canada, most notably in Montreal, where the first indoor hockey game was played on March 3, 1875. Some characteristics of that game, such as the length of the ice rink and the use of a puck, have been retained to this day. Amateur ice hockey leagues began in the 1880s, and professional ice hockey originated around 1900. The Stanley Cup, emblematic of ice hockey club supremacy, was first awarded in 1893 to recognize the Canadian amateur champion and later became the championship trophy of the NHL. In the early 1900s, the Canadian rules were adopted by the Ligue Internationale de Hockey Sur Glace, the precursor of the IIHF and the sport was played for the first time at the Olympics during the 1920 Summer Olympics.
