2 August 1908 – The King Of All Clásicos
River, the older of the two clubs, formed in Buenos Aires's La Boca district in 1901, while Boca Juniors arrived there two years later. Despite their proximity, they did not meet until 1908 in a friendly. Records from the day are sparse, but indicate that Boca won by the score of 2-1. Despite losing that first match, River got a measure of revenge by winning the first competitive meeting 2-1 in 1913.
Since then, the rivalry has grown to become one of the most passionate in football. The teams have played each other a total of 338 times, including friendlies, league matches, Copa Libertadores meetings, and other competitions. Of those, Boca have 132 wins, River have 119, and there have been 115 draws.
