Cape Verde when Portuguese explorers discovered and colonized the islands, establishing the first European settlement in the tropics. Ideally located for the Atlantic slave trade, the islands grew prosperous throughout the 16th and 17th centuries, attracting merchants, privateers, and pirates. The end of slavery in the 19th century led to economic decline and emigration. Cape Verde gradually recovered as an important commercial center and stopover for shipping routes. Incorporated as an overseas department of Portugal in 1951, the islands continued to campaign for independence, which was peacefully achieved in 1975. Since the early 1990s, Cape Verde has been a stable representative democracy,
Cape Verde–United States relations time and continues today. The first U.S. consulate in sub-Saharan Africa was established in Cape Verde in 1818. U.S. consular representation continued throughout the 19th century. The United States recognized Cape Verde on its independence day and supported its admission to the United Nations. Cape Verde assigned one of its first ambassadors to the United States, and a resident U.S. ambassador was posted to Cape Verde in 1983. Prime Minister Jose Neves visited Cape Verdean communities in New England during an official trip to the United States in 2002, and President Pedro Pires visited the United States in April 2005.
