Match ends, MK Dons 5, Yeovil Town 1.
MK Dons secured promotion to the Championship with a commanding victory over relegated Yeovil Town, as rivals Preston suffered defeat at Colchester.
Needing to better Preston's result to go up, Carl Baker fired in from 20 yards out to put the Dons ahead.
Dean Lewington's free-kick doubled the lead, before Darren Potter and Will Grigg made it four before the break.
Jordan Spence's own goal reduced the advantage, but Lewington's late second wrapped up the crucial three points.
Baker picked up Samir Carruthers's pass and shot low into the far corner to settle the home fans' nerves.
Lewington's curling left-footed strike left Yeovil goalkeeper Artur Krysiak with no chance, and the Dons captain then turned provider to set up the next two goals.
The midfielder first nodded down for Potter to power in a close-range volley, before his cross was met by Grigg, who headed in the club's 100th league goal of the season.
Yeovil squandered their only chance of the half when Joel Grant fired over, but they did pull one back when Spence turned into his own net from close-range.
Lewington's bullet header, coupled with George Moncur's late effort for Colchester, ensured that MK Dons reached the second tier for the first time in the club's history.
MK Dons manager Karl Robinson told BBC Three Counties Radio:
"I just feel numb. What an amazing 12 months we've had. A year ago we were playing Leyton Orient here in a nothing game and we were bowled over.
"I'm just so proud of the players. Every single player gave their all from the first whistle to the last whistle of the season. It's an amazing day, we'll never ever forget it."
