The final whistle at Wembley was greeted with an outpouring of joy by Newcastle fans, as their side sealed a win that means a trophy finally goes back to Tyneside after a 56-year wait.
This triumph will mean as much as any trophy ever won by the Magpies and ensures a place in Geordie history for Howe - the manager who engineered the triumph - and the team who thoroughly merited a victory that will live forever in the hearts and minds of their fans.
It will also mean a place in Europe next season.
Newcastle carried more energy and threat throughout than a limp Liverpool, although the final moments played on the nerves of all those in black and white when Chiesa's goal was given after lengthy deliberation by the Video Assistant Referee for offside.
Boyhood Newcastle fan Burn was called up by new England boss Thomas Tuchel on Friday - and the 32-year-old defender crowned the finest week of his career by taking advantage of slack Liverpool marking to open the scoring.
Isak doubled the Magpies' lead with a superbly taken strike which gave Newcastle well-deserved breathing space after the break.
Howe's side were superior to Liverpool in all areas, with Joelinton giving a momentous performance in midfield - rallying supporters after winning tackles and never giving Arne Slot's team a moment's peace.
This win marks a historic moment for Newcastle, ending the barren years and a run of nine successive Wembley defeats since they lifted the FA Cup seven decades ago.
It started the party of all parties inside Wembley - and one that will carry on all the way back to Tyneside.
