Manchester United is the most successful football club in England domestically, winning the League Championship a record 20 times. The club also has 11 FA Cup wins too though their haul of 3 European Cup/Champions League victories is still bettered by Liverpool FC with 6.
They were the first English side to compete in the European Cup in 1957 reaching the semi finals but in 1958 they were struck by tragedy when, travelling home from a European Cup fixture in Belgrade their plane crashed on take-off in Munich, killing 23 people including 8 first team players.
Busby rebuilt his side from the ashes of this tragedy triumphing ten years later in the European Cup final at Wembley with a side containing one of the survivors of that plane crash, Bobby Charlton. With this win, United became the first English side to win the European Cup.
The club embarked on another period of unprecedented success in 1986 when it appointed current manager Sir Alex Ferguson. Since his appointment in 1986, United won 13 league titles, 5 FA Cups and 2 European Cups as well as the European Cup Winners Cup. They also won the FA Cup and league double 1994 and 1996 and the treble (with Champions league in 1999).
