1883 FA Cup final

The 1883 FA Cup final was an association football match between Blackburn Olympic F.C. and Old Etonians F.C. on 31 March 1883 at Kennington Oval in London. It was the 12th final of the world's oldest football competition, the Football Association Challenge Cup (commonly known as the FA Cup). Old Etonians were the holders of the Cup, having defeated Olympic's local rivals, Blackburn Rovers, in the 1882 final. Blackburn Olympic had not previously progressed beyond the first round of the competition. Both teams had been victorious in six previous rounds to reach the final.

Old Etonians took the lead in the first half with a goal from Harry Goodhart, but Alfred Matthews scored an equaliser for Blackburn and, with the scores level at the end of the regulation 90 minutes, the game went into extra time, during which Blackburn's James Costley scored and Blackburn won the match 2–1. It was the first time that a working-class team had won the competition, which had previously been won exclusively by teams of wealthy amateurs. The victory intensified a debate over professionalism in football which had been ongoing since the previous decade; following threats by teams which wished to pay their players to break away and create a new governing body, professionalism in football was legalised in 1885 and the dominance of the gentleman amateurs quickly ended.
