In 1973 Don Revie's Leeds were expected to clinch their second consecutive FA Cup trophy when they took on Bob Stokoe's Sunderland.
In one of the competition's biggest shocks, Sunderland won 1-0 and became the first Second Division side to win the FA Cup since West Brom's 1931 triumph.
Sunderland took the lead on 32 minutes when Ian Porterfield scored from 12 yards and Leeds were then denied by an outstanding display of goalkeeping from Jimmy Montgomery.
Midway through the second half he made a famous double save, palming away Trevor Cherry's header and then diverting Peter Lorimer's follow-up blast onto the crossbar. It was not to be Leeds' day.
Seventeen years later however, they went some distance towards reclaiming the date as a special anniversary, Lee Chapman's goal at Bournemouth securing the Second Division title on goal difference.
The striker's header allowed Leeds to pip Sheffield United to the title and it not only delivered promotion back to the big time but sent hosts Bournemouth down. An estimated 5,000 Leeds fans made the trip to the coast, in sweltering heat, to see their heroes finish the job.
“Having so many games to get through takes a heavy toll both mentally and physically," said skipper Gordon Strachan.
“I have picked up twelve or thirteen medals in my career but I can honestly say that none have been harder to win than this Division Two medal."
The day was marred somewhat as a number of Leeds fans were involved in violent clashes with the police and home fans.
Strachan was scathing of the trouble makers: "We, the players, want to make one thing clear. The lads at Elland Road have won this championship not for the troublemakers but for the genuine, well-behaved supporters who have backed us in the right manner.
“Unfortunately, there are a few hundred morons – and that is what they are, morons – who tarnish the name of the club with their actions. If those people think the championship is theirs, then they should think again. And they can call me what they like for that.”
On this day in 1996 both John Lukic and Gary McAllister made their final appearances for Leeds in a goalless draw with Coventry at Highfield Road.
And fast forwarding another 10 years, Leeds drew 1-1 with Billy Davies' Preston North End at Elland Road in the first leg of the Championship play-off semi-final. David Nugent opened the scoring for the visitors before Eddie Lewis levelled for Leeds. The celebrations of Preston and their boss fuelled the fire for a Leeds victory in the second leg that sent them to Wembley
