The National Hockey League was born in Montreal, Canada, during a historic meeting meant to establish a new framework for professional ice hockey. Following various conflicts and disagreements within the National Hockey Association, league executives gathered to discuss the future of the sport. The NHA's inability to maintain stability prompted its leaders to devise a new organization, which ultimately led to the formation of the NHL. The five teams that first participated included the iconic Montreal Canadiens and the Toronto Arenas, each of which would go on to play pivotal roles in the development of ice hockey as a premier sport in North America.

In its inaugural season, the NHL adopted rules designed to ensure the longevity and integrity of the league. The goals included expanding the fan base, enhancing competitive play, and instituting better player agreements. The rule changes focused on regulating team operations, player transfers, and scheduling, offering a more structured approach compared to its predecessor. Establishing territorial rights also reinforced the rivalry and competitive spirit among the teams.

Throughout the years, the NHL's reputation grew, attracting talented players and increasing its fan base significantly. Over the decades, the league expanded beyond its original cities, leading to the formation of the Canadian and American divisions. The NHL faced challenges, including the Great Depression and later, the introduction of competing leagues. However, adaptations and resilience helped pave the way for its evolution into one of the most popular sports leagues in the world, recognized for its skilled athletes and passionate fanbase.
