Fluminense Football Club (abbreviated as "Fluminense", English name: Fluminense RJ) was founded on July 21, 1902, and is a football club located in the Laranjeiras neighborhood of Rio de Janeiro, Brazil.
The team’s first official match was an 8-0 victory against the now-defunct Rio Football Club, and in 1906 they won their first state championship. In 1911, internal disagreements led to the formation of Flamengo, and the rivalry match known as the "Flamengo Derby" became a classic in Brazilian football. During the 1950 World Cup, the Maracanã Stadium, the largest in the world, was completed and became the home ground of Fluminense. In 1951, the team won the Rio League championship, and the following year they participated in the Rio Cup, advancing as group leaders and defeating Austria Vienna and Corinthians to win the title.
In the 1970s, the team signed stars like Carlos Alberto, and the "Tricolor Machine" won the state championship in 1975 and 1976. They claimed the Campeonato Brasileiro title again in 1984 and won the state league championship three consecutive years from 1983 to 1985. In 1996, the team was relegated from the Campeonato Brasileiro, but due to off-field maneuvers, they remained in the league. They were relegated again in 1997 and fell from the second division to the third division in 1998. In 1999, the team won the third division championship and was invited to participate in the João Havelange Cup, and in 2001, they remained in the first division due to tournament rules.
In 2013, the team reached the quarter-finals of the Copa Libertadores, and after the last round of the Campeonato Brasileiro, they seemed to be relegated. However, due to points deductions for violations by teams like Flamengo, they narrowly avoided relegation. In 2014, Darío Conca returned, and the team spent most of the time in the top five of the Campeonato Brasileiro, ultimately finishing in sixth place.
