1735 - Between Spain and Portugal

The Creoles from Santa Fe province crossed over into the wide plains which lie between the Parana and the Uruguay, and defeated the Charrua tribes who had kept the Spanish out of that region for one hundred and fifty years. Soon the gauchos were in possession of Entre Rios as far as the Uruguay. The Charruas east of the Uruguay could not prevent the gauchos from making their way across the river to build their cabins and ride the plains after cattle.

The settlement of western Uruguay began, but, except Colonia and Soriano, no towns were founded. The half-Indian gauchos lived a seminomadic life and needed and received little help from the authorities in their constant fights against the Indians.

Shortly after the foundation of Montevideo, a Portuguese expedition tried to recover the place, but it was found to be too strong to attack, and the party resolved to establish a town farther up the coast. Three hundred miles to the north-west is found the only opening into the great system of lagoons which stretches along the seaward side of Rio Grande do Sul, and at that strategic point the Portuguese, in 1735, built a fort and town.

By the middle of the eighteenth century, the situation between Spain and Portugal in the whole region between the Plate, the Uruguay, and the sea had become very strained. Colonia was completely isolated and the Spaniards controlled all the rest of Uruguay's western and southern water-front. The Portuguese settlements in the seaward half of Rio Grande were prospering and multiplying, soon to furnish thousands of gauchos, as ready as any who rode the Argentine pampas to sally forth for war or plunder.

The territory which the Jesuits had held for more than a century on the east bank of the Upper Uruguay lay directly back of these Portuguese settlements and was more easily accessible therefrom than from Montevideo. In 1750 Spain agreed to exchange the Seven Missions for Colonia. The Portuguese promptly took measures to secure the ceded territory, attacked the Indian villages, and massacred or drove off most of the inhabitants. The Jesuits vigorously protested, and outraged Spanish public opinion demanded the abrogation of the treaty, so a few years later the desolated territory was restored to Spanish possession and Colonia remained Portuguese.

In 1762 Spain and Portugal were again engaged in war, and the governor of Buenos Aires attacked Colonia with a force of twenty-seven hundred men and thirty-two ships. The fortifications were strong and the Portuguese offered a tenacious resistance. After a well-contested siege the place surrendered, only to be given back to Portugal the ensuing year. Meanwhile, troops had been sent up from Montevideo against Rio Grande and the Portuguese settlers driven back to the north-east corner of the state, only to rise again when the Spanish troops were gone and to begin a guerrilla warfare which never ceased until they had regained their towns.

The eighteenth century had entered on its last quarter before the Spanish home government took any real steps to drive the Portuguese out of Colonia and to reclaim the disputed territory as far north as Sao Paulo. The Atlantic slope of Spanish South America was erected into a Viceroyalty, and in 1777 the greatest fleet and army ever sent by Spain to America reached Buenos Aires under command of the new Viceroy.

The Portuguese had no forces able to cope with his army and fleet, and he carried all before him. The island of Santa Catharina in the north of the disputed territory was captured, Colonia was taken, and an army of four thousand men started on a triumphal march north-westward to sweep the Portuguese from the coast. The Spaniards were at the gates of Rio Grande when news came that peace had been declared. Orders from home compelled the Viceroy to stop his northward progress while the diplomats agreed on a division.

The sc-called First Treaty of San Ildefonso of 1777 between Spain and Portugal settled in Uruguay a region in this time called orbe novo. The treaty of San Ildefonso in the main gave each country the territory its citizens actually occupied. The Seven Missions remained Spanish, and the Portuguese were deprived of the southern half of the great lagoon and of Colonia. Santa Catharina was restored, and the right of Portugal to the vast interior and to the regions of the Upper Parana and Paraguay were confirmed. Rio Grande remained Portuguese and Uruguay was assured of being thenceforth and for ever Spanish in blood and speech.
