Uruguay is by far the nation with the smallest population to have ever hoisted a World Cup and for most years, are among (and consistently) one of the strong footballing nations, albeit the population size. So much so, there footballing history goes deeper than 1930, where they have won and championed the olympic games, even before winning the first ever World Cup. They wear four stars above their emblem, to signify also the 1924 and 1928 Summer Olympics, which FIFA for those two years, technically recognize as World Championships.
Uruguay's golden generation is aligned with those first early twenty five years (from the Olympic Games to their second World Cup victory in 1950). Where both World Cup victories came against the perceived two giants of South American futbol/ soccer being Brazil and Argentina. The first World Cup final was against Argentina, which folks ended up dubbing the game, "un juego del barrio" or a "game from the neighborhood". The 1950 Final, which was being hosted in Brazil (in Maracana), in the famous the Maracanazo match, still remains the most highly-attended football match ever played (with official number nearing the 174K) people.
The saying goes if you contract an Uruguayan player for your club football team, the worst of the Uruguayan signings will at the bare minimum support and bring something to the team,. Where at any given point in any generation, the best of the signings, and there will be a handful of Uruguayan players at any point and time, will be one of the highest quotes and priced footballers in the world. It is remarkable and extraordinary when you put it in its proper context. Argentina and Spain are the 2nd and 3rd smallest countries to hoist the World Cup Title, and Uruguay is 13 times smaller in population than them. And when compared to Brazil, the largest population for a World Cup champion, they are 61 times smaller than them.
Uruguay capitalized very early in developing and understanding a futbol/ soccer that was required to play in order to win in the early stages of global competition. It is still a remarkable feat that they stay and are often times a threat or power player, given the size of their country. You have recent players like Luis Suarez (all time Uruguayan goal scorer), Edinson Cavani, Diego Forlan, or Diego Godin (most capped Uruguayan player).
Other major championships: They have won 15 Copa Americas with 6 runner ups.
