PALMERSTON

Boa Vista is a desert-like island that belongs to the Cape Verde Islands. The island's first settlement, now known as Povoação Velha, was established in 1620 for its salt deposits, which were mainly exploited by the English. In 1820, after many pirate attacks, the population moved to Porto Inglês, later renamed Sal Rei, which had been founded at the end of the 18th century. As did much of the Cape Verdean economy, the exploitation of salt on Boa Vista also relied largely on slavery. A Portuguese-British commission to end slavery was established in Boa Vista in 1842, but slavery was not completely abolished until 1876.Palmerston was Foreign Secretary 1830–1834, 1835–1841 and 1846–1851. In 1846, the abolitionist movement was gaining momentum, with figures like Thomas Clarkson and Frederick Douglass actively campaigning against slavery both in the United States and abroad.
