Adrião Acácio da Silveira Pinto

Adrião Acácio da Silveira Pinto (born late 18th century – died 1868) served as a staff officer (Captain, later Lieutenant-General) during Liberal Wars in the Duke of Terceira's army which landed in the Algarve and marched north to Lisbon in 1833. Later he was appointed to be a Portuguese colonial administrator who held the position of Governor of Macau between 1837 and 1843. During the Opium Wars, fearing Chinese reprisals he requested the British community to leave Macau. The British sailed off to Hong Kong on August 1839. Later he was Governor-General of the Province of Angola between 1848 and 1851. As a governor of Angola, Pinto acknowledged that enslaved individuals, particularly Black Africans, had a natural inclination to escape slavery, and this was partly attributed to slave owners using them as itinerant traders in the interior regions (sertões) of Angola, which provided ample opportunities for escape.
