Rio de Janeiro | History, Population, Map, Climate, & Facts (2024)

Rio de Janeiro, city and port, capital of the estado (state) of Rio de Janeiro, Brazil. It is located on the Atlantic Ocean, in the southeastern part of the tropical zone of South America, and is widely recognized as one of the world’s most beautiful and interesting urban centres. Although Rio de Janeiro continues to be the preeminent icon of Brazil in the eyes of many in the world, in reality its location, architecture, inhabitants, and lifestyle make it highly unique when compared with other Brazilian cities, especially the country’s capital of Brasília or the much larger city of São Paulo. The former is a much smaller city dating back only to the 1960s, while the latter is a huge, sprawling commercial and manufacturing centre with none of Rio’s spectacular natural beauty or captivating charm. Unlike Rio, both are located on flat interior plateaus.

The name was given to the city’s original site by Portuguese navigators who arrived on January 1, 1502, and mistook the entrance of the bay for the mouth of a river (rio is the Portuguese word for “river” and janeiro the word for “January”). When the foundations of the future town were laid in 1565, it was named Cidade de São Sebastião do Rio de Janeiro (“City of St. Sebastian of Rio de Janeiro”) for both São Sebastião and Dom Sebastião, king of Portugal.

Rio de Janeiro became the colonial capital in 1763 and was the capital of independent Brazil from 1822 until 1960, when the national capital was moved to the new city of Brasília; the territory constituting the former Federal District was converted into Guanabara state, which formed an enclave in Rio de Janeiro state. In March 1975 the two states were fused as the state of Rio de Janeiro. The city of Rio de Janeiro became one of the 14 municipalities of the Metropolitan Region of Rio de Janeiro, or Greater Rio, and was designated the capital of the reorganized state. Despite loss of the status, funding, and employment it had enjoyed as Brazil’s capital, Rio de Janeiro not only survived but thrived as a commercial and financial centre, as well as a tourist magnet. Area city, 485 square miles (1,255 square km); Greater Rio, 2,079 square miles (5,384 square km). Pop. (2022) 6,625,849; Greater Rio, 11,875,063; (2021 est.) 6,775,560; Greater Rio, 12,763,305.

Character of the city

Rio de Janeiro is well known for the beauty of its beaches and of its peaks, ridges, and hills—all partly covered by tropical forests. The city is a centre of leisure for Brazilian and foreign tourists, and people wearing bathing suits can be seen walking in the streets and along the beaches or traveling on the city’s buses. Perhaps at no time is the city’s festive reputation better displayed than during the annual pre-Lenten Carnival, which enlivens the city night and day with music, singing, parties, balls, and street parades of brilliantly costumed dancers performing to samba rhythms. Rio is also an important economic centre, however, with activities ranging from industry and national and international trade to administration, banking, education, culture, and research.

The city’s economic and social prominence grew in the 18th century after it became the main trade centre for the gold- and diamond-mining areas of nearby Minas Gerais. Later its status as a national capital and as the royal residence of the Portuguese monarch influenced Rio’s continued growth and helped it acquire a cosmopolitan atmosphere and a national character, free of regional conflict. After the city was relegated to being a state capital in the mid-20th century, however, a new regional consciousness began to develop. While São Paulo became entrenched as Brazil’s economic heartland and Brasília strengthened its position as the political hub, residents of Rio increasingly prided themselves on being the country’s cultural centre and Brazil’s most salient symbol to the rest of the world.
