In the first “official” world cup held in Uraguay, only 13 nations took part.

(7 from South America, 4 from Europe and 2 from North America. Times have changed though. 200 teams entered the 2002 FIFA World Cup qualification rounds; 198 attempted to qualify for the 2006 FIFA World Cup, while a record 204 countries entered qualification for the 2010 FIFA World Cup.)
