Rio Grande was founded in 1737 by Jose da Silva Paes, who built a fort on the river near the site of the present city and called it Estreito. In 1745 the garrison and settlement was removed by Gomes Freire d'Andrade to its present site, which became a "villa," in 1751, with the name of Sao Pedro do Rio Grande, and a "cidade" (city) in 1807. It was the capital of the captaincy down to 1763, when it was captured by a Spanish force from Buenos Aires under the command of its governor, Don Pedro Zeballos, the seat of government being then removed to Viamao at the northern end of Lagoa dos Patos. The city was occupied by the national forces in the ten years' war which began in 1835, and in 1894 it was unsuccessfully besieged by a small insurgent force that had attempted to overthrow the government at Rio de Janeiro.
