Steven Gerrard's Invincibles smashed through the 100-point barrier for the first time in Rangers' history as the champions kicked off their trophy-day celebrations in style.
A 4-0 win over Aberdeen - earned thanks to a Kemar Roofe double in between Joe Lewis's early own goal and Jermain Defoe's late fourth - ensured an undefeated campaign. But the match was merely a distraction ahead of the main event.
Thousands of fans locked outside Ibrox were really waiting for the moment when skipper James Tavernier finally lifted the trophy the club have waited a decade to recapture. It was met by a barrage of fireworks as the Light Blues faithful lit Glasgow up in red, white and blue.
It has been a momentous, record-breaking season for Gerrard and his team, who have finished a monstrous 25 points clear of Celtic.
Victory over the Dons not only wrapped up a perfect 100 per cent home record in the league, but also saw them write a number of new entries in the history books.
They have now set a new Scottish clean-sheet record with their 26th shut out, and the 13 league goals they have conceded this term is also a record low - beating the previous benchmark of 15 set by Jose Mourinho's 2005 Chelsea side.
Rangers end title-winning season Invincible
The throngs outside Ibrox ignored warnings from the club, Police Scotland and the Scottish Government to stay away from the stadium.
The temptation to join the party was just too much for them to resist and their team ensured the atmosphere was not soured by completing their historic march to a blemish-free campaign.
The champions needed only five minutes to take the lead. Ianis Hagi clipped a tidy ball out to Tavernier on the right-hand side.
The skipper's cross took a big deflection off Dons youngster Jack MacKenzie before Lewis's attempted punch to clear went all wrong, with the ball flying backwards off his fist and into his own net.
Connor Goldson almost marked racking up 5,000 consecutive minutes of action this term with a goal, heading wide from a corner.
Aberdeen are still getting the hang of Stephen Glass's new methods. It is taking a bigger adjustment for some more than others, as demonstrated when Lewis knocked a goal-kick straight out for a corner as one attempt to build from the back bombed.
But they were unlucky not to level when a slick counter-attack saw Florian Kamberi release Jonny Hayes down the left, with the Irishman's cross just out of Callum Hendry's reach.
The Dons have been toothless in 2021, netting just nine times since the turn of the year.
Rangers have managed more than that in the last month and extended their lead after 34 minutes.
Ryan Kent got a lucky break as he went up against Connor MacLennan but from then on there was no catching the winger as he darted towards the byline, cutting back for Roofe to slot home past Lewis.
Aberdeen introduced Fraser Hornby at the break but his first involvement was to waste another big chance from a Ryan Hedges cross. Unselfishly he then teed-up Lewis Ferguson to tap into an empty net but the midfielder somehow smashed the ball against the crossbar from six yards.
While the visitors continued to fire blanks, Rangers' finishing was laser-guided. Tommie Hoban's loose pass was pounced on by Hagi as he fed Roofe, who swept home his second with an expert low finish on the hour.
Rangers were being careless, however, and newly-crowned SPFL Player of the Year Allan McGregor had to underline his award-winning credentials with a fine block after Hedges was allowed to surge through on goal.
There was still time for Rangers to put gloss on a historic day as Greg Stewart slid in Defoe to score as Rangers ensured the party started with a bang.
