History:

The first recorded rugby game in the US was played at Cambridge on May 5, 1874 between Harvard University and Montreal’s McGill University. The match between two universities sparked interest among the other colleges and universities nationwide. Rugby’s popularity in the US reached new heights when the national team claimed victories in the 1920 and 1924 Olympic Games. A dormant period, however, ensued after this period as American rugby was heavily affected by the removal of rugby from the Olympic roster of sports. American rugby’s revival came in the 1960s-1970s, with the formation of the national governing body. The United States of America Rugby Football Union, now known as USA Rugby, was created in 1975. To date, USA Rugby consists of seven Territorial Unions (TUs) and 37 Local Area Unions (LAUs),and supports more than 50,000 members.
