The Rangers supporters went Radio Ga Ga as their heroes stormed to their first flag in four years in magnificent style.
They scored three times without reply at a venue where they had not won for three years.
And it is fantastic testament to the form the team has put together in the climax of the season claiming eight wins and a draw in their final nine fixtures.
Deserving champions? You better believe it.
Kyle Lafferty, Pedro Mendes and Kris Boyd claimed the goals on an utter joy day for Walter Smith’s side, who have now created their own bit of history.
Smith, of course, savoured the sweet taste of 9 in a row at Tannadice 12 years ago but this title must feel equally as good.
The financial ramifications are huge of course as Rangers qualify directly to the group phase of the Champions League.
But that’s for another day. Today Rangers basked in the glory of winning the title for the 52nd time.
They could scarcely have made a better start when they took the lead with a little over five minutes played.
Steve Davis, who was superb all day, was the man behind the move when his drive got him into an excellent position on the right side of the United box.
He whipped the ball over and Kris Boyd appeared to miss-kick as he attempted a shot on goal but the ball broke to Kyle Lafferty who swept the ball into the net with his left foot.
Tannadice erupted into a wall of Rangers noise and Lafferty, who has not had an easy week, almost ripped his shirt off in celebration.
Davis had served notice of his threat with a similar move in just two minutes but neither Boyd nor Kenny Miller could make contact.
Then the little Ulsterman carved out another opening in eight minutes when Pedro Mendes’ free kick broke to him and he tried to pick out Miller but the striker shot over the bar under pressure from Mihael Kovacevic.
United, though, came back into the game in the middle period of the half and lone striker David Goodwillie proved to be a difficult opponent.
Only a terrific challenge from Sasa Papac stopped him from having a clear sight of Neil Alexander’s goal.
Rangers, though, had another excellent chance in 38 minutes and United were fortunate to survive.
Papac’s cross from the left broke to Boyd and he swivelled in the centre of the box and took aim with his left foot. Lukasz Zaluska was beaten but the ball hit Kovacevic and diverted wide for a corner.
Mendes whipped over the subsequent corner and Madjid Bougherra rose well at the near post but glanced his header over the bar.
The Portuguese star, however, was to play an infinitely more significant role seven minutes later.
Rangers won a free kick just outside the United box on the right side after a heavy challenge by Darren Dods on Mo Edu.
Papac tried to have a pop at goal but the ball broke out to Mendes on the left side of the United box and he showed superb composure to drill a low left foot shot into the right corner.
The Rangers legions went bananas because they knew the massive importance of the moment.
And they were dancing joyously just six minutes into the second half when Rangers scored a third goal and sealed the deal. In that instant the title was theirs.
It was a terrific move and a trademark finish from Scotland’s leading goal-scorer, Kris Boyd.
Davis played the ball forward and Mendes sweetly laid off to Stevie Whittaker who had over-lapped on the right side.
United were ripped wide open and Whittaker drove over a low pass which Boyd swept into the net with his left foot right in front of the ecstatic Rangers supporters.
The game was over and so was the title race. United’s spirit was crushed and Rangers cruised through the remainder of the match towards to the throne of Scottish football.
Nacho Novo, so often impactful this season, came on to keep United occupied and Barry Ferguson got the last 18 minutes and undoubtedly savoured what might his last involvement as a Rangers player.
Novo might have scored a fourth in 77 minutes when he squeezed past Gary Kenneth but Zaluska made a good block with his body. It mattered little.
It was a stunning end to a roller coaster season.
