The Argentine Rugby Union (, abbreviated "UAR") is the governing body for rugby union in Argentina. It is a member of World Rugby, with a seat on that body's Executive Council, and a founding member of Sudamérica Rugby. The UAR organises all the national teams, including Senior (Pumas), U-20 (Pumitas), Argentina XV, Sevens and Women's squads and the franchise Jaguares that participates in SANZAAR's Super Rugby competition. History Origins The first rugby match in Argentina was played in 1873, in the Buenos Aires Cricket Club Ground sited in Palermo, Buenos Aires. Only 24 players (all of them were English) could meet to contest the match. The teams were named Bancos ("Banks" in Spanish) and Ciudad ("City") and formed with 11 and 13 players respectively.

The teams were called El bando del Sr. Trench ("Mr. Trench's side"), and El bando del Sr. Hogg ("Mr. Hogg's side"). Nevertheless, other sources say that the first game under the rules of rugby was played on Thursday, 14 May 1874, at David Mathven's country house, in Caballito, Buenos Aires. Buenos Aires FC also played the first inter-provincial rugby game in Argentina, when it faced Rosario AC in the city of Rosario, on 28 June 1886. First championship organized In 1899, clubs Belgrano, Rosario, Lomas, Buenos Aires and Flores founded the "River Plate Rugby Union", naming Leslie William Corry-Smith as President. The body organized the first championship that same year, played by the five founding members. In the inaugural game, Lomas defeated Buenos Aires by 11-4.
