Angered by a controversial umpiring decision, cricket spectators rioted and attacked the England team during a match in Sydney, Australia.

In cricket, an umpire is a person who has the authority to make decisions about events on the cricket field according to the Laws of Cricket. Besides making decisions about legality of delivery, appeals for wickets and general conduct of the Game in a legal manner, the umpire also keeps a record of the deliveries and announces the completion of an over.

Cricket is a bat-and-ball game that is played between two teams of eleven players on a field, at the centre of which is a 22-yard pitch with a wicket at each end, each comprising two bails balanced on three stumps. Two players from the batting team, the striker and nonstriker, stand in front of either wicket holding bats, while one player from the fielding team, the bowler, bowls the ball toward the striker's wicket from the opposite end of the pitch. The striker's goal is to hit the bowled ball with the bat and then switch places with the nonstriker, with the batting team scoring one run for each of these swaps. Runs are also scored when the ball reaches the boundary of the field or when the ball is bowled illegally.

The Sydney Riot of 1879 was an instance of civil disorder that occurred at an early international cricket match. It took place on 8 February 1879 at what is now the Sydney Cricket Ground, during a match between New South Wales, captained by Dave Gregory, and a touring English team, captained by Lord Harris.

The England men's cricket team represents England and Wales in international cricket. Since 1997, it has been governed by the England and Wales Cricket Board (ECB), having been previously governed by Marylebone Cricket Club since 1903. England and Wales, as founding nations, are a Full Member of the International Cricket Council (ICC) with Test, One Day International (ODI) and Twenty20 International (T20I) status. Until the 1990s, Scottish and Irish players also played for England as those countries were not yet ICC members in their own right.
