Rio de Janeiro

Guanabara Bay was reached by a Portuguese expedition under Florentine explorer Amerigo Vespucci, that included Portuguese explorer Gaspar de Lemos, on January 1, 1502; hence Rio de Janeiro, "January River." There is a legend that the mariners named the place thus because they thought the mouth of the bay was actually the mouth of a river, but no experienced sailor would make that mistake. At the time, river was the general word for any large body of water.

Several years after the Portuguese first explored Brazil, French traders in search of pau-brasil (a type of brazilwood) reached the rich area extending from the Cape Frio coast to the beaches and islands of Guanabara Bay, the economic and, above all, strategic importance of which was already well-known.

In 1555, one of the islands of Guanabara Bay, now called Villegagnon Island, was occupied by 500 French colonists under admiral Nicolas Durand de Villegaignon. Consequently, Villegagnon built Fort Coligny on the island when attempting to establish the France Antarctique colony, which the French called Henriville in honor of Henry II of France.

On March 1, 1565 the city is founded. Until early in the 18th century, the city was threatened or invaded by several, mostly French pirates and buccaneers, such as Jean-François Duclerc and René Duguay-Trouin. After 1720, when the Portuguese found gold and diamonds in the neighboring captaincy of Minas Gerais, Rio de Janeiro became a much more useful port for exporting wealth than Salvador, Bahia, which is much farther to the north. In 1763, the colonial administration in Portuguese America was moved to Rio. The city remained primarily a colonial capital until 1808, when the Portuguese royal family and most of the associated Lisbon nobles, fleeing from Napoleon's invasion of Portugal, moved to Rio de Janeiro. The kingdom's capital was transferred to the city, which, thus, became the only European capital outside of Europe. As there was no physical space or urban structure to accommodate hundreds of noblemen who arrived suddenly, many inhabitants were simply evicted from their homes.
