Plymouth secured the Sky Bet League One title on the final day of the season as they came from behind to beat Port Vale 3-1.
The home side opened the scoring after just three minutes with a perfect through ball beyond the defence finding its way to James Plant, who slotted home.
Despite going behind, Plymouth did not panic and eventually forced an equaliser in the 34th minute when a loose ball in the box fell to Adam Randell, who made no mistake on the half-volley.
The momentum led to another four minutes later with a blistering run down the line from Bali Mumba eventually leading to a cross which Joe Edwards was on the end of.
Argyle were determined to add to their tally after the break and scored a third after just over an hour as a Finn Azaz shot from just outside the 18-yard box was too good for Aidan Stone to stop.
The full-time whistle prompted huge celebrations from the 3,926 away support.
Schumacher: Promotion means the world - the journey back will be lively!
Plymouth manager Steven Schumacher:
"This means the world to us, we've fought so hard week in and week out since the last day of last season when we just fell short in the play-offs. The work has been going since then and we felt we could mount a challenge.
"All the staff, all the players, everybody has just given everything they've got and we managed to become champions. We've deserved it. The game was a good game, credit to Port Vale. I thought they had a great spirit and played the game the right way.
"They took a great goal to score, but our lads showed brilliant character to come from behind and win the game. The bus journey back is going to be very lively. Everybody should be really proud and now it's time to get the party started."
