Germany and other Iron Curtain nations including Hungary, Poland and Czechoslovakia were excluded from this early-1950s Brazilian international club football tournament due to Cold War tensions. FC Nurnberg (West Germany) was even barred by a domestic law in 1952, and FC Saarbrucken took its place. Which tournament is this?

Question

Accepted Answer

Copa Rio (international tournament). The Copa Rio was an international club football tournament organised by Fluminense and the Brazilian FA in 1951 and 1952, often cited as a forerunner of the FIFA Club World Cup. Palmeiras won the inaugural 1951 edition and Fluminense the 1952 edition; the political geography of the early Cold War shaped which European clubs could actually attend.
