Short answers, pulled from the story.
The Maracanazo was Uruguay's 2-1 victory over host nation Brazil in the deciding match of the 1950 FIFA World Cup, played on the 16th of July at the Estádio do Maracanã. Brazil needed only a draw to win the trophy, but Alcides Ghiggia scored for Uruguay with just over eleven minutes remaining. Goalkeeper Moacyr Barbosa was blamed for the defeat and carried that weight for the rest of his life.
Both were cancelled because of World War II. The competition did not return until 1950, leaving a twelve-year gap since the previous tournament in 1938.
Thirteen teams competed. Sixteen had originally qualified, but Scotland, Turkey, India, and France all withdrew before or after the draw, reducing the field to thirteen.
Brazil's Ademir was the top scorer at the 1950 FIFA World Cup, finishing with nine goals.
Scotland withdrew because George Graham, chairman of the Scottish Football Association, had declared that Scotland would only travel to Brazil as winners of the 1949-50 British Home Championship. Scotland finished second behind England, and Graham refused to change his position despite pleas from Scottish captain George Young and England captain Billy Wright.
The 1950 FIFA World Cup replaced the traditional one-match final with a four-team round-robin group stage, making it the only World Cup in history decided without a single final. Brazilian organisers proposed the format to guarantee thirty games rather than sixteen, and threatened to withdraw as host until FIFA agreed.
