Clube de Regatas do Flamengo, commonly known as Flamengo, is a major Brazilian multi-sports club based in Rio de Janeiro, best known for its successful football team. Founded in 1895 as a rowing club, Flamengo evolved into one of Brazil's most prominent football teams. The club's name is derived from the Flamengo neighborhood, which itself was named after the word "Flemish" in reference to the Dutch navigator Olivier Van Noort, who attempted to invade Rio de Janeiro in the 16th century.
 
Flamengo is celebrated for its remarkable football history, never having been relegated from Brazil's top division since the formation of the national league, a distinction shared with São Paulo FC. With more than 46.9 million supporters, Flamengo has the largest fan base in Brazil, representing about 21.9% of the country's football fans. The club's deep-rooted rivalries with Rio de Janeiro’s "Big Four" teams—Fluminense, Botafogo, and Vasco da Gama—are among the fiercest in Brazil. Additionally, Flamengo has significant interstate rivalries, especially with Atlético Mineiro and Palmeiras.
 
Financially, Flamengo is the richest football club in Brazil, generating an annual revenue of R$1.2 billion (€218 million) and valued at over R$3.8 billion (€691 million). In addition to its financial strength, the club boasts the largest social media following of any non-European football club, with 49 million followers as of mid-2023, highlighting its global appeal and influence.
 
On the pitch, Flamengo has enjoyed immense success domestically and internationally. The club has won multiple Brasileirão Série A titles, including back-to-back championships in 2019 and 2020, as well as several Copa do Brasil trophies.
 
Internationally, Flamengo is a three-time winner of the prestigious Copa Libertadores, claiming titles in 1981, 2019, and 2022, establishing itself as a force in South American football. The club also won the 1981 Intercontinental Cup, defeating Liverpool and further enhancing its international reputation.
 
Flamengo's significance goes beyond football, as it embodies Rio de Janeiro's working-class culture and spirit. The club’s loyal fans, known as "Flamenguistas," create a thrilling atmosphere, particularly at Maracanã Stadium, with their famous chants and unwavering support. The red and black stripes of Flamengo's kit are iconic, symbolizing both the club’s proud history and its close bond with its supporters.
 
In summary, Flamengo is a symbol of football excellence, cultural pride, and a strong community. Its rich history, unrivaled fan base, and continued success on and off the field make it a cornerstone of Brazilian and international football.
