The first detailed map of Uruguay

A very rare map of Uruguay, lithographed by Napoléon Chaix, with the western border following the Parama river from Rio de la Plata to Asunción. It was published under the direction of Aimé Roger, the French consul, and was dedicated to Fructoso Rivera, who had been the first president of the country. This was a mark of French support for Rivera, during the Uruguayan Civil War, when he controlled very little outside Montevideo. Two years later the Rivera's opponents had the city was under a siege that lasted nine years.
