Arguments and cancelled gigs are nothing new for Oasis. For them, spectacular popularity has always gone hand-in-hand with spectacular bust-ups.
But neither brother has formally left the band - until now. Noel Gallagher has quit, saying he can no longer work with brother and bandmate Liam.
As fans question whether this really is the end, the troubles and triumphs they have shared over the years are recalled below.
- 1991 - The band form with an original line-up of the Gallagher brothers, Paul "Bonehead" Arthurs, Paul "Guigsy" McGuigan and Tony McCarroll, initially under the name Rain.
- May 1993 - Discovered by Creation Records owner Alan McGee while playing third on the bill at Glasgow venue King Tut's Wah Wah Hut. He offers them a record deal on the spot.
- February 1994 - The world gets the first taste of their bad behaviour when Liam and Guigsy are detained on a ferry for causing mayhem in the bar en route to a gig in Amsterdam. They are immediately deported.
- April - Debut single Supersonic is released. Oasis are at the forefront of Britpop - an explosive time for British guitar music, with bands that dominated the charts and the airwaves.
- April - Liam and Noel are at each others' throats during an infamous interview with NME, proving rows are nothing new. The following year, the recording is released on 7" single under the title Wibbling Rivalry.
THE BIG TIME
- September 1994 - Debut album Definitely Maybe reaches number one in UK.
- August - A fan jumps on stage and punches Noel in the face, cutting him with his ring, before Noel and Liam hit back. Bottles are thrown as the band abandon the gig, and the crowd smashes the windows of the tour bus as they leave the venue.
- February 1995 - Oasis are named best British newcomers at the Brit Awards - but arch rivals Blur win four awards, including best British group.
- August - Amid much media hysteria, Oasis release their single Roll With It on the same day that Blur release Country House. In the great Battle of Britpop, Blur score number one and Oasis lose out.
- September - Guigsy, suffering from nervous exhaustion, refuses to go on tour. The band recruit an unknown replacement, Scott McLeod. But he walks out suddenly after just a month, prompting the Gallaghers to scrap the rest of their US dates. Guigsy later returns.
- February 1996 - Oasis get revenge on Blur at the Brit Awards, winning three gongs, including best group and best album for What's The Story Morning Glory.
- August - They play to 250,000 people over two nights at Knebworth, now widely seen as the high point of both Britpop and Oasis's fortunes.
- September - At Heathrow Airport, Liam backs out of a US tour 15 minutes before the flight. He says he has to find a new house with wife Patsy Kensit instead of playing to "silly Yanks". The tour starts without him and he flies out later. But relations boil over and two weeks later, Noel cancels the remaining dates.
- August 1997 - Third album Be Here Now sells 663,000 copies in the UK in its first week. It still holds the record for the fastest-selling album.
