most heated in the sport, due to their local and global popularity. River's home stadium, Estadio Monumental is the largest in the country. Apart from football, the club hosts a large variety of sports such as athletics, basque pelota, bowls, chess, basketball, handball, cestoball, gymnastics, field hockey, karate, roller hockey, roller skating, swimming, taekwondo, tennis, volleyball, waterpolo, and eSports. History According with the club's official version, River Plate was founded on 25 May 1901, close to the La Boca neighborhood (later the home of fierce rivals Boca Juniors). The institution was formed after the merger of two clubs, "Santa Rosa" and "La Rosales", with Leopoldo Bard being elected as its first president. The name was chosen because of an incident during the construction of Buenos Aires Port: one of the members had seen how the workers of Dique nº 3 left their duties for a while to play a football match. The boxes they were working with just said "The River Plate" (the name the English gave to the Río de la Plata) and that inscription was taken to name the new club. River Plate affiliated to the Argentine Football Association in 1905, debuting in the third division against Facultad de Medicina. On 13 December 1908, the team was promoted to first division after beating Racing Club 2–1. However, the match was declared null due to River supporters jumping onto the field to celebrate with the players, so a new match had to be played. River again won, this time 7–0, to achieve promotion. In 1914 River won its first domestic championship, the Copa de Competencia Jockey Club and its first international title, the Copa de Competencia Chevallier Boutell. The nickname Los Millonarios came after the acquisition of winger Carlos Peucelle in 1931 for $10,000 and Bernabé Ferreyra for $35,000 (Large sum of money for the period) in 1932. In the following years, River Plate consolidated its place as one of the most popular teams of Argentina, and the 20th century brought much success. The club's record of 28 official tournaments saw them dubbed El Campeón del Siglo (The Champions of the Century).
