Paraguay, officially the Republic of Paraguay, is a country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of 7 million, nearly 3 million of which live in the capital and largest city of Asunción, and its surrounding metro. Although one of only two landlocked countries in South America, the country has coasts, beaches and ports on the Paraguay and Paraná rivers that give exit to the Atlantic Ocean through the Paraná-Paraguay Waterway.
Spanish conquistadores arrived in 1524, and in 1537 established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Jesuit missions, where the native Guaraní people were converted to Christianity and introduced to European culture. After the expulsion of the Jesuits from Spanish territories in 1767, Paraguay increasingly became a peripheral colony, with few urban centers and settlers.
