On 3 April 1905, Club Atletico Boca Juniors was founded in the La Boca neighborhood of Buenos Aires by five Italian immigrants - Esteban Baglietto, Juan Farenga, Teodoro Farenga, Santiago Sana, and Alfredo Scarpati. The first match was played on 21 April 1905. The photo above is the first-known photograph of Boca Juniors, taken in 1906.
Boca Juniors play in blue and yellow, which the club reportedly patterned after the colors of the Swedish flag. Prior to that, Boca played in shirts with black and white vertical stripes, which were also used by another local club. In 1906, the two clubs played a match, with the winner keeping the stripes. Boca lost, and decided to use the colors of the first ship to sail into port at Buenos Aires, which was a Swedish freighter. Thus Boca adopted their now-famous blue and yellow kits.
Boca won their first title - the Argentinian amateur championship - in 1919, starting a series of successes that now includes 31 domestic and 18 international trophies, making them one of the most decorated clubs in history. Their achievements include four Intercontinental Cup/FIFA Club World Cup titles (in 1977, 2000, 2003, and 2007).
A number of international stars have played for Boca, including Juan Roman Riquelme (1995-2002 and again from 2007-present), Carlos Tevez (2001-04) and Argentine football legend Diego Maradona (1981-82, 1995-97).
