The Greater Chicago Soccer League, formerly the National Soccer League (Chicago), formed by the merger of the Chicago Soccer League and International Soccer Football League of Chicago in 1928, is a semi-professional U.S. soccer league which claims to be the oldest continuously operating soccer league in the United States.
In 1904, the Association Football League of Chicago (AFLC) was established as an ethnic British league in Chicago, Illinois. While the AFL, and others like it, catered to the British and Irish expatriate communities, there were few opportunities available to the rest of Chicago's many immigrant groups to play organized, competitive soccer. In 1913, the Chicago Soccer League came into existence. In 1915, it merged with the AFLC to form the Chicago and District Association Football League (CDAFL). However, this new league was better known as the Chicago Soccer League. In 1919, several non-British teams left the CDAFL to form the International Soccer League. This league lasted only one year, but led to the founding of the International Soccer Football League in 1920. That year the ISFL, with Frank Foldi as its president, was created to address the lack of league opportunities for non-British teams. With teams from nearly every significant ethnic group in Chicago, the ISFL quickly established itself as a major player in Chicago soccer.[1] The league grew in strength as most of the city's other amateur and semi-professional league collapsed. In 1924, Carl Johnson of the ISFL's Swedish-Americans, became the first U.S. player from outside the north-east capped by the national team. In 1930, the ISFL created a junior division to give young players an opportunity to develop their talents at a high level en route to a spot on a first division roster. This served to enhance the league's stability as it grew its own talent pool. In 1938, only the Chicago Soccer League and the International Soccer Football League remained as the top two city leagues. That year, they merged to form the National Soccer League of Chicago.
World War II hit the NSL hard as most of the top players were inducted in the armed forces. However, the end of the war brought a renaissance when those men returned from the military, to be quickly followed by western and central European immigrants fleeing the devastation caused by the war. A few years later, another wave of immigrants, this time Eastern Europeans fleeing communism, brought another fresh group of talented players into the NSL.[2] These waves of immigration led to an expansion of the league into multiple divisions including junior and youth teams. While centered on Chicago, the league expanded to include teams from towns surrounding the city.
In 1950, the National Soccer League created the first indoor soccer league in the United States. Chicago leagues had played indoor tournaments for decades but this was the first time an annual competitive indoor season was founded. The league featured twelve teams with games broadcast live on radio. This indoor adjunct of the NSL was continued until 1968. That year, the North American Soccer League was created as a division one league. While the NASL struggled at times and ultimately folded in 1984, it created a national league which drew the best U.S. players away from the traditional regional and city leagues which had dominated U.S. soccer. This brought the slow eclipse of the National Soccer League of Chicago as a major player in U.S. soccer. The collapse of the NASL in 1984 brought a brief resurgence to the NSL, but the founding of Major League Soccer in 1996, along with the merger of the A-League and USISL in 1997 to form the USL First Division led to the decline of the NSL. The league continues as a local recreational league, but its teams are no longer the competitive force on the national level they once were.
The NSL, in response to the COVID-19 pandemic in March 2020, cancelled the last two rounds of matches in indoor play as well as the playoffs.[3] Later, the outdoor season would be cancelled as well.[4] This marked the first time in the NSL's century-long history since World War II a season would not be played.
In 2023 the NSL and the competing Metropolitan Soccer League were officially merged as the Greater Chicago Soccer League, with the teams playing a common schedule in March before a formal merger happened in December, with the accompanying change of name.[5]
