Rugby union in Argentina is a hugely popular team sport. The first rugby match played in the country dates back to 1873, as the game was introduced by the British. The Argentina national team, sometimes referred to as the Pumas, have competed at the Rugby World Cup, and are considered a tier one nation by the sport's governing body, World Rugby. Governing body The Argentine Rugby Union (UAR) was formed in 1899 as the "River Plate Rugby Union", 26 years after the first rugby match had been played. It was affiliated to the English Rugby Football Union until 1932. The union is a member of World Rugby with two seats and three votes on that body's Executive Council. The UAR is one of the oldest rugby unions in the world. The union became a member of the International Rugby Football Board, later known as the International Rugby Board and now as World Rugby, after being invited to the inaugural Rugby World Cup in 1987. Popularity Rugby enjoys widespread popularity in Argentina, most especially in the Greater Buenos Aires urban area, which boasts more than eighty rugby clubs, and Tucumán Province. While rugby in Argentina is still largely amateur, there are many professional players. Prior to the country's entry into Super Rugby in 2016, most national team members played professionally in Europe, mainly in England and France. Today, most members of the national team play on the country's Super Rugby side, the Jaguares. History Rugby union began to be played in Argentina in 1873, exclusively by the resident British people to begin with. The first rugby union match in Argentina was played that same year in the Buenos Aires Cricket Club Ground, located in Palermo neighbourhood, where the Galileo Galilei planetarium is located today. Both teams (called "Bancos" and "Ciudad" for the occasion) were formed by members of the BACC and they play a mix between football and rugby. On 29 June 1886, it is recorded that Buenos Aires F.C. (predecessor of current Buenos Aires Cricket & Rugby Club) and Rosario A.C. played the first inter-clubs match in Plaza Jewell, Rosario, Santa Fe. The line-ups were: Rosario: C.E. Baines, W. Graham, A. Musgrove, A. Williamson, R.C. Baines (captain), A. Dickenson, Boland, Geary, E.D. Graham, Hall, Hanckel, Parry, Smyth, Topping, Towse. Buenos Aires: G.E. Gunson, F.J. Bennett, W.R. S. Baikie (captain), J.C. Hutchings, J. Nisbet, A. H. Scott, W.P. Drabble, J. Earnshaw,
