Rio Grande do Norte

Rio Grande do Norte is one of the 26 states of Brazil. It is in the northeastern part of the country. It is on the edge of the South American continent.
Geography
Rio Grande do Norte has a large coastline. The state is well known for its beaches and sand dunes. The air is the cleanest in South America.
Because of a large mountain chain called Serra da Borborema, Rio Grande do Norte has two main climates. The area along most of the coastline is very tropical. Inland, much of the state is very dry.
The dry climate is not only because by the low amount of rainfall but also because of the fact that it rarely rains at all. Often years go by with no or very little rain. Most of the interior of the state is part of the Polygon of Droughts. This is an area which gets special attention from the federal government.
Rocas Atoll belongs to the state of Rio Grande do Norte. It is in the Atlantic Ocean, 260 km Northeast of Natal.
History
The first European to come to the region may have been the Spaniard Alonso de Ojeda in 1499. The northeastern tip of South America, cape Sao Roque, was first seen by European navigators in 1501. This was during a 1501-1502 Portuguese expedition led by Amerigo Vespucci. He named the spot after the saint of the day. The Vespucci expedition also named the Potengi river, "Rio Grande". The name is Portuguese for "Great River". The area and state were named after the river. For decades, no permanent European settlement was made in the area.
Between 1535 and 1598, the area was explored by French pirates. In 1598, the Portuguese built the Forte dos Reis Magos. The next year, they created the city of Natal.
In 1633, the area was fought over between the Portuguese and the Dutch. In 1654, the Dutch were finally cast out.
During World War II, Rio Grande do Norte was used as an Allied airbase. The base was used to attack German-occupied North Africa.
In 1964, Latin America's first space launch site was built in Rio Grande do Norte; Barreira do Inferno (Hell's Barrier). It is often called the "Brazilian NASA".
Economy
Historically, the economy of Rio Grande do Norte has been based on sugar and cattle. In the 1980s, the state government realised that tourism was a very good industry. Since then, more money has been used to build places for tourists and repair colonial buildings in major cities.

To the sides of the shield are a coconut palm to the right and a carnauba palm to the left. The two palms are connected by two branches of sugarcane.
