Morocco became the first African nation to reach a World Cup semi-final and ended the hopes of Cristiano Ronaldo's Portugal.
Striker Youssef En-Nesyri scored the winning goal in the first half, leaping highest to beat goalkeeper Diogo Costa to the ball and heading in to spark pandemonium at Al Thumama Stadium.
The north African side's supporters populated most of the venue and joyously celebrated their breakthrough moment for their continent on the global stage.
Ronaldo came off the bench in the 50th minute to equal the men's all-time appearance record of 196 in international matches, but he could not drag his side back into the contest.
Morocco were happy to play on the counter and grabbed the opener just before the break when En-Nesyri headed in from Yahya Attiyat-Allah's cross.
Portugal skipper Bruno Fernandes came agonisingly close to levelling just minutes later but a brilliant individual effort struck the crossbar.
Decimated by injuries, Morocco sat back for the majority of the second half and Yassine Bounou brilliantly tipped over Joao Felix's drive - the closest they came to an equaliser.
Morocco striker Walid Cheddira was sent off for a second yellow card in eight minutes of additional time but Portugal could not find the equaliser as their last-four hopes were dashed.

GOAL - Morocco 1-0 Portugal
We have lift-off!
This might be a shock score line but it's not a surprise given the way the game has been played.
Morocco have been fantastic on the ball, that is one of the best goals of the tournament. the build-up through the midfield, little one-twos and the keeper is absolutely nowhere.
Technically, they have been the better team in this game and they deserve to be 1-0 up.

Around seven minutes plus stoppages before the interval. Morocco do not want half-time to come. They are enjoying their best spell going forward and their pace is causing Portugal problems.

Half a chance for Morocco.
Youssef En-Nesyri rises high to meet a set-piece but his header flies over the bar.
They've still to test Portugal keeper Diogo Costa in what has so far been a cagey game.
18:25
Ouch!
Bono goes up to pluck a cross out of the air but is completely flattened by Bruno Fernandes.
The referee races over to the two players. It's fair to say Morocco's players were not impressed with Fernandes for that.

Morocco immediately respond with an attack of their own which ends with a chance flying over the bar but it would not have counted as there was an offside.
Nevertheless, this has been a lively start.

A huge chance for Portugal!
A free-kick is delivered into the Morocco box and Joao Felix forces Bono into a flying save.
That was a powerful header and the Morocco keeper did well to beat it behind for a corner.
