Brazil Campeonato Carioca

The 20th century saw in Rio de Janeiro and Niterói a significant popularity in football with the establishment of clubs such as Rio Cricket and Athletic Association in Niterói, Fluminense Football Club in 1902, and Bangu Atlético Club, América Football Club, and Botafogo Football Club in 1904 being founded. Organizing leagues for competition amongst clubs followed by Rio Cricket and Athletic Association, Fluminense Football Club, Football and Athletic Club, America Football Club, Bangu Atlético Club, Sport Club Petrópolis and Payssandu Cricket Club. On June 8, 1905, the Liga Metropolitana de Football (abbreviated LMF, Metropolitan Football League in English) was founded. LMF's first president was Bangu's José Villas Boas, who was replaced by Francis Walter in December of the same year.

In 1906, the first Campeonato Carioca was contested by six clubs: Fluminense, Botafogo, Bangu, Football and Athletic, Payssandu and Rio Cricket. America, despite being one of the league founders, did not contest the league's first edition. Fluminense became the first Rio de Janeiro state champion.

In 1907, the championship ended with a tie between Botafogo and Fluminense. The league rules did not address ties. Botafogo claimed an extra-match advantage; Fluminense claimed that the league should adopt the goal-average criteria. It went unresolved until 1996 when both clubs were declared champions.

On February 29, 1908, Fluminense, Botafogo, America, Paysandu, Rio Cricket, and Riachuelo founded Liga Metropolitana de Sports Athleticos (LMSA, meaning Metropolitan Athletic Sports League), the organizer of the 1908 Campeonato Carioca. Fluminense won.

The first league split was in 1911 when Botafogo left LMSA and founded Associação de Football do Rio de Janeiro (AFRJ - Rio de Janeiro Football Association). The league was nicknamed Liga Barbante (String League), because Botafogo was the only significant club to question the full realisation of the sport under LMSA. AFRJ was incorporated by LMSA in 1913.^[]

In 1917, several accusations of bribery caused LMSA to rebrand as Liga Metropolitana de Desportos Terrestres (Terrestrial Sports Metropolitan League) (LMDT). Fluminense won the competition of that year.

On March 1, 1924, a second league split occurred, and Associação Metropolitana de Esportes Athleticos (Athletic Sports Metropolitan Association) was founded. AMEA, founded by the "aristocratic" clubs Flamengo, Fluminense, Botafogo and America, with restrictions on its blacks and lower class citizens to their members. The Confederação Brasileira de Desportos (CBD - Brazilian Sports Confederation) remained with AMEA recognizing it as the official league of Rio de Janeiro from 1924 on, and disassociating with LMDT. AMEA's competition was won by Fluminense. LMDT's (The league was nicknamed Liga Barbante) (String League) competition was won by Vasco da Gama, the only significant club that remained on the old league. In 1925, AMEA rescinded its racial conditions and Vasco left LMDT, while LMDT continued with its minor clubs. Years later, the LMDT championship of 1924 was considered official - but not the following LMDT championships.^[]

On January 23, 1933, Bangu, Fluminense, Vasco and America founded the first professional league of Rio de Janeiro, Liga Carioca de Futebol (LCF) (Carioca Football League). The Confederação Brasileira de Desportos was an amateur-only league supported AMEA. For this reason, LCF was nicknamed "pirate league". In 1934 CBD finally accepted professionalism, but LCF and AMEA did not merge for political reasons. On December 11, 1934, Botafogo, Vasco, Bangu, São Cristóvão, Andaraí, Olaria, Carioca and Madureira founded the professional Federação Metropolitana de Desportos (FMD) (Sports Metropolitan Federation), replacing AMEA as the official Rio de Janeiro league affiliated to CBD.

In 1937, the Brazilian football clubs were professionalized. On July 29, 1937, FMD and LCF merged, creating Liga de Football do Rio de Janeiro (Rio de Janeiro Football League), also called LFRJ. In 1941, LFRJ rebranded as Federação Metropolitana de Futebol (FMF) (Metropolitan Football Federation). The occasion was celebrated by a friendly match between Vasco da Gama and America that would come to be nicknamed Clássico da Paz (Peace Derby) for any game played between the two teams.

On April 21, 1960, the Brazilian capital city became Brasília, so, Federação Metropolitana de Futebol rebranded as Federação Carioca de Futebol (FCF) (Carioca Football Federation). América won the state championship of that year.

On March 15, 1975, Rio de Janeiro and Guanabara states merged under the name of Rio de Janeiro.

On September 29, 1978, Federação de Futebol do Estado do Rio de Janeiro (Rio de Janeiro State Football Federation) (FERJ), was founded, after Guanabara state's FCF and Rio de Janeiro state's FFD (Federação Fluminense de Desportos, or Fluminense Sports Federation) fused.

In 1979, there was an extra Campeonato Carioca which also included the countryside state teams, which, until that year, contested the Campeonato Fluminense. This extra competition, known as Primeiro Campeonato Estadual de Profissionais (First Professionals State Championship) was won by Flamengo, which was also the champion of the regular competition, but did not count in the overall titles.

In 1996, Taça Cidade Maravilhosa was contested only by clubs from Rio de Janeiro city. This competition was contested by eight teams (America, Bangu, Botafogo, Flamengo, Fluminense, Madureira, Olaria and Vasco da Gama), which played against each other once. Botafogo was the champion, Flamengo being the runner up. In the same year, a state championship was played, won by Flamengo.
