Soccer is a family of team sports that involve, to varying degrees, kicking a ball to score a goal. Unqualified, the word football usually means the form of football that is most popular where the word is used. The sport is commonly called association football (known as soccer in North America and Oceania); gridiron football (especially American football or Canadian football); Australian rules football; Rugby Union and Rugby League; and Gaelic football. These different forms of football share common origins to varying degrees and are known as football codes.
There are several references to traditional, ancient or prehistoric ball games in different parts of the world. Contemporary codes of football can be traced back to the codification of these games in 19th century English public schools. The expansion and cultural influence of the British Empire allowed these rules of football to spread to areas of British influence beyond the empire directly controlled. By the end of the 19th century, distinct regional codes had already developed: Gaelic football, for example, deliberately incorporated local traditional football rules to preserve their traditions. In 1888, the Football League was founded in England, becoming the first of many professional football organizations. In the 20th century, various forms of football became the most popular team sport in the world.
The various codes of football share some common elements and can be divided into two main categories of football: American football, Canadian football, Australian football, rugby union and rugby league, where the ball is moved around the field during play. hand or throw, and kicking codes such as association football and Gaelic football, where the ball is primarily moved with the feet and where handling is strictly limited.
