Manchester United Football Club is an English professional football club, based in Old Trafford, Greater Manchester, that plays in the Premier League. Founded as Newton Heath LYR Football Club in 1878, the club changed its name to Manchester United in 1902 and moved to Old Trafford in 1910.

The 1958 Munich air disaster claimed the lives of eight players. In 1968, under the management of Matt Busby, Manchester United was the first English football club to win the European Cup. The current manager, Sir Alex Ferguson, has won 37 major honours since he took over in November 1986.

Manchester United has won the most trophies in English football, including a record 19 league titles, a record 11 FA Cups, four League Cups and 19 FA Community Shields. The club has also won three European Cups, one UEFA Cup Winners' Cup, one UEFA Super Cup, one Intercontinental Cup and one FIFA Club World Cup. In 1998–99, the club won a "Treble" of the Premier League, the FA Cup and the UEFA Champions League, an unprecedented feat for an English club.

Old Trafford is a football stadium in Old Trafford, Greater Manchester, England, and the home of Manchester United. With a capacity of 75,811, Old Trafford is the second-largest football stadium in England after Wembley, the third-largest in the United Kingdom and the eleventh-largest in Europe. The stadium is approximately 0.5 miles (0.8 km) from Old Trafford Cricket Ground and the adjacent tram station.

The ground, nicknamed the Theatre of Dreams by Bobby Charlton, has been United's permanent residence since 1910, with the exception of an eight-year absence from 1941 to 1949, following the bombing of the stadium during the Second World War. During this period, the club shared Maine Road with local rivals Manchester City. The ground underwent several expansions in the 1990s and 2000s, including the addition of extra tiers to the North, West and East Stands, which served to return the ground almost to its original capacity of 80,000. Future expansion is likely to involve the addition of a second tier to the South Stand, which would raise the capacity to over 90,000. The stadium's record attendance was recorded in 1939, when 76,962 spectators watched the FA Cup semi-final between Wolverhampton Wanderers and Grimsby Town.
