Rules

• 26 October — foundation by local clubs of the Football Association (FA) in London. The first set of Laws is drafted, based mainly on the Cambridge University Rules. The purpose is to regulate English football under a single code of rules, but the rugby football clubs do not join because of the ball handling issue. Their attempt at compromise between the "dribbling" and "handling" codes is rejected by the dribblers and so rugby football becomes in time an entirely separate sport. The FA rules establish association football (aka football or "soccer") as a distinct sport.
• Apart from their main purpose of introducing standard rules of play and procedure, the Laws seek to differentiate between association football and rugby football. The essential difference in the two codes is encapsulated in Laws 9 and 11 which state that no (outfield) player shall run with the ball (in his hands) and that no (outfield) player shall throw the ball or pass it to another with his hands. The Laws will be amended later to clarify the situation at throw ins and during possession by goalkeepers but the FA is emphatic from the start that "hand ball" is illegal during normal play.
• These Laws are originally known as the "London Rules" because they are only adopted by some London clubs and hardly anywhere else. Several clubs exist in Sheffield at the time and they play to the so–called Sheffield Rules. Gradually the FA, led by Charles Alcock, manages to persuade the clubs that a uniform set of rules is desirable and, after many adaptations and compromises, the FA rules eventually become standard.
• The rejection of handling causes the "Rugby rules" clubs and colleges to withdraw from the FA and they will eventually found the Rugby Football Union in 1871.

Clubs founded

• Probable foundation of Stoke City as Stoke Ramblers, although it is not known to have played any matches until 1868. If founded in 1863, it is the second oldest senior professional club playing association football after Notts County.
