where did the idea of football come from
History of American football The history of American football can be traced to early versions of rugby football and association football. Both games have their origin in varieties of football played in Britain in the mid-19th century, in which a football is kicked at a goal or kicked over a line, which in turn were based on the varieties of English public school football games.
American football American football, referred to as football in the United States and Canada, and also known as gridiron football or simply gridiron, is a sport played by two teams of eleven players on a rectangular field with goalposts at each end.[nb 1] The offense, which is the team controlling the oval-shaped football, attempts to advance down the field by running with or passing the ball, while the defense, which is the team without control of the ball, aims to stop the offense's advance and aims to take control of the ball for themselves. The offense must advance at least ten yards in four downs, or plays, and otherwise they turn over the football to the defense; if the offense succeeds in advancing ten yards or more, they are given a new set of four downs. Points are primarily scored by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins.
