Three islands--Sal, Boa Vista, and Maio--generally are level and very dry. Mountains higher than 1,280 meters (4,200 ft.) are found on Santiago, Fogo, Santo Antão, and São Nicolau.

Sand carried by high winds has created spectacular rock formations on all islands, especially the windward ones. Sheer, jagged cliffs rise from the sea on several of the mountainous islands. Natural vegetation is sparse in the uplands and coast, but interior valleys support denser growth.

In 1462, Portuguese settlers arrived at Santiago and founded Ribeira Grande (now Cidade Velha)--the first permanent European settlement city in the tropics. In the 16th century, the archipelago prospered from the transatlantic slave trade. Pirates occasionally attacked the Portuguese settlements. Sir Francis Drake sacked Ribeira Grande in 1585. After a French attack in 1712, the city declined in importance relative to Praia, which became the capital in 1770.

With the decline in the slave trade, Cape Verde's early prosperity slowly vanished. However, the islands' position astride mid-Atlantic shipping lanes made Cape Verde an ideal location for resupplying ships. Because of its excellent harbor, Mindelo (on the island of São Vicente) became an important commercial center during the 19th century.

Portugal changed Cape Verde's status from a colony to an overseas province in 1951 in an attempt to blunt growing nationalism. Nevertheless, in 1956, Amilcar Cabral, a Cape Verdean, and a group of Cape Verdeans and Guinea-Bissauans organized (in Guinea-Bissau) the clandestine African Party for the Independence of Guinea-Bissau and Cape Verde (PAIGC), which demanded improvement in economic, social, and political conditions in Cape Verde and Portuguese Guinea and formed the basis of the two nations' independence movement. Moving its headquarters to Conakry, Guinea in 1960, the PAIGC began an armed rebellion against Portugal in 1961. Acts of sabotage eventually grew into a war in Portuguese Guinea that pitted 10,000 Soviet bloc-supported PAIGC soldiers against 35,000 Portuguese and African troops.

By 1972, the PAIGC controlled much of Portuguese Guinea despite the presence of the Portuguese troops, but the organization did not attempt to disrupt Portuguese control in Cape Verde. Portuguese Guinea declared independence in 1973 and was granted de jure independence in 1974. Following the April 1974 revolution in Portugal, the PAIGC became an active political movement in Cape Verde. In December 1974, the PAIGC and Portugal signed an agreement providing for a transitional government composed of Portuguese and Cape Verdeans. On June 30, 1975, Cape Verdeans elected a National Assembly, which received the instruments of independence from Portugal on July 5, 1975.

Immediately following the November 1980 coup in Guinea-Bissau, relations between Cape Verde and Guinea-Bissau became strained. Cape Verde abandoned its hope for unity with Guinea-Bissau and formed the African Party for the Independence of Cape Verde (PAICV). Problems have since been resolved, and relations between the countries are good. The PAICV and its predecessor established a one-party system and ruled Cape Verde from independence until 1990.
