Immigration to Uruguay recovered in 1848 and 1,684 French Basques settled in the country from 1848 to 1850, still the exclusive destination for French immigration in the River Plate basin as the French blockade of Buenos Aires lasted until 1850, and around 1,415 between 1850 and 1855, when Argentina had finally overcome Uruguay as the main destination for French immigrants in South America. Until 1853, French Basques formed the most numerous group among all immigrants in Uruguay, and French immigration as a whole remained predominant until 1862, when it definitely became surpassed in numbers by Spaniards and Italians. As a consequence, French immigrants and their Uruguayan-born children made up more than a third of Uruguay's population by 1860, representing a 78,000-strong community in a country still sparsely populated (including future Presidents Juan Campisteguy and Juan Idiarte Borda, both born to French Basque parents).
