Milan have been crowned as Serie A champions for the first time since the 2010-11 campaign after beating Sassuolo.
Stefano Pioli's men went into the final day of the season knowing they simply needed to avoid defeat to clinch their first Scudetto in over a decade.
The Rossoneri had established a two-point lead over rivals Inter – against whom they also held a head-to-head advantage – at the Serie A summit.
And they made sure of their success with a 3-0 defeat of Sassuolo, thanks to goals from Olivier Giroud and Franck Kessie.
Milan travelled to Sassuolo having made light of a challenging run-in, winning five consecutive games to tee up their historic triumph, as they matched the Nerazzurri's tally of 19 Italian top-flight titles. Only Juventus (36) have more than the two Milanese giants.
While Inter avoided handing the title to the Rossoneri following a hard-fought 3-1 win over Cagliari last weekend, their result against Sampdoria on the final day was ultimately immaterial as Milan made their advantage count at the end of an absorbing title race.
The Rossoneri's last title triumph came under the tutelage of Massimiliano Allegri some 11 seasons ago, with Zlatan Ibrahimovic, Alexandre Pato, and Robinho each scoring 14 Serie A goals apiece as Milan finished six points clear of Inter.
Pioli's men have been able to rely on a fantastic defensive record to get them over the line, conceding just eight league goals since the turn of the year.
Indeed, 11 of Milan's 17 Serie A clean sheets this season have come in 2022, and last week's crucial 2-0 win over Atalanta marked the first time they had kept five consecutive home clean sheets in Serie A since a run of six under Carlo Ancelotti in 2002.
The Rossoneri's title win also marks the first major trophy of Pioli's coaching career, and the club's first trophy win since the 2016 Supercoppa Italiana.
