Early rugby was not immune to political problems either. An 1890 game in Buenos Aires resulted in both teams, and all 2,500 spectators being arrested. National president Juárez Celman was particularly paranoid after the Revolution of the Park in the city earlier in the year, and the police had suspected that the match was in fact a political meeting. In 1899, four clubs from Buenos Aires (Buenos Aires, Belgrano, Flores and Lomas) and one from Rosario (Rosario A.C.) got together to form "The River Plate Rugby Union". That same year the Union organised the first club championship (currently Torneo de la URBA), which was won by Lomas. This body, one of the oldest rugby unions in the world, later became known as the Argentine Rugby Union (UAR), which became a member of the International Rugby Board (IRB) only after being invited to the inaugural Rugby World Cup in 1987. From the founding date until 1903, the only teams taking part in tournaments had been founded by English natives or their descendants. Only they knew the rules of the game and their families were from the high society. It was only in 1904 when the first team formed by "criollos" made its appearance, named "Centro de Estudiantes de la Facultad de Ingeniería". Some players of that team were the Newbery Brothers, Martín Miguens, Alberto Lagos, Luis Duhau, Mariano Paunero and Germán Dates. Although rugby went professional in the mid-1990s, the domestic competition in Argentina has largely remained amateur. That has ensured large numbers of Argentines playing overseas, particularly in European competitions, though these players are still eligible for the national team, and make up a large amount of the side. It was originally dominated by the British community in Argentina, but unlike certain other regions, it became successfully transplanted to the local population. For example, in its early days the River Plate Rugby Union (the ancestor of today's national organisation), had a membership whose surnames portrayed their English and Scottish origins - such as Anderson, Baikie, Bellamy, Brodie, Corry-Smith, Elliot, Jacobs, Leicht, Taylor, Thurn. Away from Buenos Aires, where the game's background is traditionally somewhat refined, Tucuman is a heartland for the sport, where supporters are passionate, and often burn the opposition's
