Oneida Football Club

The Oneida Football Club, founded and captained by Gerrit Smith Miller in Boston, Massachusetts, in 1862, was the first organized team to play any kind of football in the United States. The game played by the club, known as the "Boston game", was an informal local variant that combined association and rugby football and predated the codification of rules for American football.The team, made up of students of Boston's elite preparatory schools, played on Boston Common from 1862 to 1865, during which time they reportedly never lost a game or even gave up a single point.After Oneida disbanded, former members established the Harvard University Football Club, which continued to play under the Boston game rules.
