Palace did not win their first Premier League game this season until 27 October, but faith in the Austrian never wavered and the payback is this big prize - as well as a place in the Europa League next season.
Eberechi Eze and Dean Henderson have been two standout heroes on the road to Wembley, and they inspired the Eagles once again as City were punished at one end and thwarted at the other.
Eze provided the moment of magic, as he did in the quarter-final win at Fulham and the semi-final win against Aston Villa at Wembley, pouncing ruthlessly on Munoz's cross to leave Stefan Ortega helpless.
City will forever believe Henderson should have seen red when he clawed the ball away from Erling Haaland in the first half, but VAR ruled otherwise and Henderson produced an otherwise faultless display in front of watching England head coach Thomas Tuchel.
When he dived to his right to save Marmoush's penalty, Henderson became the first keeper to save a penalty in an FA Cup final - excluding shootouts - since Petr Cech for Chelsea against Portsmouth in 2010.
City may have held sway in possession, with 78% compared to Palace's 22%, but when it mattered Eze produced the goods again.
Daniel Munoz was another standout performer for Palace, whose fans had to go through 10 agonising minutes of additional time before the memories of losing FA Cup finals in 1990 and 2016 could be banished.
Glasner's reaction, like his management, was calm and measured, while joy exploded for Palace elsewhere.
There were tears of joy on the pitch and in the stands as Palace finally sampled the sweet taste of success.

The club has promised "South London style" celebrations after claiming their first major trophy in their history.
A club statement, external continued: "There's a lot to plan, a few guests to invite, and a trophy to polish."
More details will be revealed in due course but for now the club has told their faithful fans to "keep the celebrations going".

Here are some of your comments on the Eagles' FA Cup win:
Pedro: Tears of joy as my 50 plus years of waiting comes to an end. We held our nerve, worked tirelessly, and were buoyed on by our magnificent support. I'm emotionally drained but in total ecstasy. A day to treasure.
Andy: 40 plus years of supporting Palace! What a day. Glasner the professor! Eze was the difference between the teams. What a team performance to hold Manchester City! Conceding only one goal throughout the whole tournament is brilliant!
Simon: Congratulations to Palace for an amazing performance to deny Manchester City a trophy this season. They rode their luck at times but defended to a man.
Image source, Getty ImagesJohn: They did what they set out to do which was win, albeit they had some help...
Stephen: An outstanding rear-guard effort. Muniz, Eze, Henderson and the rest of the team never stopped working.
Paul: Every player turned up today. It was a true team effort. We were solid from the back and took our chance when it came. Courage and desire. Let's hope Palace can keep most of their players and put on a good show in Europe next season!
Mark: Being Palace is special. I've loved this club since my first game as a seven-year-old, over 60 years ago. To all the other proper supporters out there, it can and will happen for your clubs. Also, stay firm. From sublime to ridiculous.

Crystal Palace Oliver Glasner has been speaking to BBC Match of the Day about the historic cup win: "I can't believe it. We had to defend so much. The spirit and togetherness on the pitch was amazing. It was all about being patient.
"We analysed that if you give them the pocket [of space] then they are so good. We had to be patient, let them cross, defend and wait for the moment to attack.
"They are so good in their movements. From the 5-2 defeat, we learned that if we give them the pocket [of space], we will lose. We usually attack more, but we had to be patient and wait for the right moment.
"When they play with four attacking players, it is difficult to defend. But in transition, we knew we could create overloads. No winger likes to defend and it was a great goal.
"Tomorrow's training is already cancelled. The players want to cancel Monday's too.
"Special credit to the players, they have never lost belief in me and the coaching staff.
"To be honest I can't really believe it. I think when you play this game 10 times, you win it once, and this happened today.
"The goal was the first time we were in their half and then we just defended with every single part of the body."
Former Palace striker Clinton Morrison on BBC Radio 5 Live: "I can't believe it. I didn't think I'd see Palace lift a trophy in my lifetime. Oliver Glasner is a special manager. What a day.
"Oliver Glasner is so detailed, everyone knows their role. I've been to the training ground and seen him work players so hard.
"Eze is not one of those who wants to run up and down in training, he wants to showboat, but in training he puts in 100% effort and that's down to the manager."
Image source, Getty ImagesCrystal Palace have won their first-ever major trophy. They are the first English club to win their first major title since Wigan Athletic in the 2012-13 FA Cup, who also beat Manchester City in the final that year.
The Eagles are the 45th side to win the FA Cup and first team to win it for the first time since Leicester City in 2021.
Daniel Munoz has been directly involved in 13 goals in all competitions for Crystal Palace this season. His six goals and seven assists are the joint-most of any Premier League defender in 2024-25 (Pedro Porro also has 13 direct involvements).
Manchester City have now lost the FA Cup final two years in a row. It is the seventh time they have finished as runners up in the competition, with only Manchester United (9), Chelsea (8) and Everton (8) doing so more times.
Pep Guardiola's side have lost 16 games in all competitions this season - their most in a single campaign since 2008-09 (23 games).
Manchester City enjoyed 76.7% possession in this match, the most on record (from 2014) in an FA Cup final. In fact, defender Ruben Dias completed more passes himself (129) than Crystal Palace did as an entire team (126).
This win qualifies Crystal Palace for next season's Europa League and it is set to be their first-ever appearance in a major European competition.
Image source, Getty ImagesCrystal Palace co-owner Steve Parish speaks to BBC Sport: "Unbelievable. This is for everybody. Everybody that has sent me a bit of encouragement when it's been going badly, all the people that stick with you, that believe, this is for them.
"I am so proud of them. Oliver Glasner made us all believe, he came with a different mentality. It's easy to say now but I didn't think they would score."
Former Palace striker Clinton Morrison on BBC Radio 5 Live: "I'm a bit emotional. It's a special time. I know what this club has been through - I was there when they going through administration.
"Palace aren't a big club but they are going to Europe and that might mean they can keep hold of one or two of their gems."
'The Eagles have landed!' - emotional full-time scenes as Palace win FA Cup
Image source, Getty ImagesFormer Premier League striker Alan Shearer has been speaking about the Eagles' winning FA Cup performance on BBC One: "They deserve it. Their fans have been sensational right throughout this game and the semi-final. It has been a fantastic atmosphere.
"Crystal Palace deserve it. I thought they were the better team. I know Manchester City put them under pressure possession-wise, but they didn't do enough in front of goal. They didn't do enough to win it or ask enough questions of Crystal Palace.
"When Oliver Glasner's side grew into the game, their confidence just got better. They worked ever so hard, the number of times they had two or three men blocking the ball in desperation and putting their bodies on the line was incredible."
On how Crystal Palace fans will be feeling: "You could see the agony on their faces when they put the 10 minutes of injury time up. All I could see was hands on heads. I just thought: 'I know how you feel, I was there a couple of months ago!'
"This is the year of the underdogs and I love it!"
Image source, Getty ImagesFormer Manchester City defender Micah Richards has been discussing Crystal Palace's FA Cup win on BBC One: "All of these games are about moments. I think there were big moments in the game that could've changed the result.
"Manchester City could have won it on another day, but Crystal Palace deserved it. They stuck in the game, they stuck to their game-plan, they knew exactly what they needed to do tactically, and they put some top performances in.
"I highlighted Munoz before the game because I think he has got genuine quality, whether it is defending or running back.
"Everything they did today was just sublime.
"You have to manage the occasion and we were questioning whether Crystal Palace could do that before the game but they dealt with it in the semi-final and today, they might have rode their luck at times, but they dealt with it again.
"They attacked when they needed to, they defended when they needed to, they got it spot on with the opportunities they had.
"It is just a momentous day for Oliver Glasner and his players."
Former Premier League striker Wayne Rooney added: "Incredible. The way they defended, blocking, bodies on the line. Henderson made some good saves. I think they deserved it.
"They stuck in there, they were resilient, hard to beat, hard to play through. Sometimes things are just meant to happen. From the semi-final you got that sense from the fans.
"Henderson's performance was incredible. The handball goes another way on another occasion but he was fantastic. I'm really pleased for him."
Ex-Palace striker Glenn Murray added: "I just think, listen to all the fans, they probably don't believe it now. Eze sank to his knees and he encapsulates everything Palace are - someone who was rejected and came back. Glasner got his tactics right today.
"It makes this summer much easier for Palace. There are people sniffing around the Ezes and Whartons but now they have reason to stay and represent this club in the Europa League."
Image source, Getty ImagesCrystal Palace's FA Cup hero Dean Henderson speaking to BBC Sport: "It's incredible. We had a feeling it would be our day today."
On his penalty save: "To be fair, Haaland might have stepped up, I wouldn't know what way he would go. Marmoush, I knew what way he was going, I knew I'd save it."
On the possible red card he could have received: "The ball held up, it was a bit dry but it doesn't matter, who cares?
"I lost my dad at the start of the season and I'll miss him today but he was with me every kick of the ball today. I dedicate that win to him."
Eberechi Eze, who scored the only goal of the game: "It's a special moment. We have come here three times as a club. To show that kind of spirit and energy, only God man.
"I couldn't breathe. They keep the ball so well, you have to work so hard. But we know when we get into the box we have to take the chance. It's not easy."
On his journey from being rejected by clubs in his teenage years: "If I am honest I don't try to forget but you guys keep reminding me of when I was 18. I have come a long way since then. To be in this position now is special, it's hard to use the right words."
Were you at Wembley or following the FA Cup final from elsewhere?
Image source, Getty ImagesFormer Premier League striker Wayne Rooney commenting on Dean Henderson's use of his hand outside the area in the first half: "It is a red card - 100% a red card.
"Erling Haaland is about to knock it around him and Dean Henderson sweeps the ball away.
"It is a red card - how can they get this wrong?"
Gary Lineker explained: "This is what VAR have said -'The direction in which Erling Haaland was going made it possible, but not an obvious goal scoring opportunity'."
Rooney replied: "Just get rid of VAR. They have made a mistake and now they are trying to cover up. It is a red card and everyone can see it's a red card. To come out with all this rubbish."
