Which two countries played the match that decided the 1950 FIFA World Cup champion?

Uruguay and Brazil played the match that decided the 1950 FIFA World Cup champion.

Unlike most World Cups, the 1950 tournament had no single-match final. Four teams—Brazil, Uruguay, Sweden, and Spain—played a final group, with the highest points total winning the championship. Before the last match, Brazil led Uruguay by one point, so Brazil needed only a draw while Uruguay needed victory.

The decisive match took place on 16 July 1950 at Rio de Janeiro’s Maracanã Stadium. Brazil scored first through Friaça, but Uruguay came back with goals from Juan Alberto Schiaffino and Alcides Ghiggia to win 2–1. Uruguay therefore claimed its second World Cup title.

The match is commonly called the Maracanazo, or “Maracanã Smash,” and is often described as the de facto final. A frequent mix-up is calling Brazil the winner because it hosted the tournament and entered the match as the favorite; Uruguay actually lifted the trophy.
