Armagh veteran Rory Grugan hailed his team's "never say die attitude" after the Orchard County overcame Galway 1-11 to 0-13 to claim their second All-Ireland title.
The sides were level at the break but Armagh got the upper hand after Aaron McKay scored the only goal of the game in the 47th minute.
The Tribesmen got to within a point but couldn't level the game after six minutes of added time.
"It's amazing, it's 10 years of work for so many people," forward Grugan told RTÉ Sport after the match.
"Just to see everyone here and the elation at the end. Boys coming off the bench again to win it for us. I can't put it into words."
Rank outsiders at the start of the season, Kieran McGeeney's side came up trumps in a tight contest after many heartbreaking defeats over the last four years.
Drama right until the end of the 2024 All-Ireland football final.

"Just to trust in what we are doing, trust in the management, the resilience we built from the the tough defeats on penalties, a never-say-die attitude," added Grugan when asked how they kept the faith.
"We kept coming back when it was easy to walk away, easy to throw in the towel but we believed in what we were doing and it's all worth it today.
"You always knew we were there or thereabouts and even though we'd lost a few games we felt like we were at a standard that was close to the top and we just weren't getting the small breaks of the ball.
"We probably rode our luck at times, things have to go for you, a ball coming off the post, a diving block, finally luck shining on us."
Armagh forward Rian O'Neill was almost lost for words at the end of the match.
"My God. That was one of the toughest games I've ever played in my life but we'll never die," he said.
"We've shown that over the last four years - we keep coming back and today we done it."
