"Infante Dom Henrique de Avis, Duke of Viseu (4 Mar 1394 – 13 Nov 1460), better known as Henry the Navigator is a high-profile figure in 15th-century Portuguese politics, and the early stages of the Portuguese Empire. He's regarded as the main initiator of the Age of Discoveries, and the Trans-Atlantic slave trade.
Henry was the third child of the Portuguese king John I."
Trans-Atlantic Slave Trade
The origins of the Trans-Atlantic slave trade begin with Prince Henry, the Navigator. In 1441, he "sent a trading expedition to Africa," that later returned with human cargo to be auctioned at Henry's Portuguese "slave market and fort in Arguin Bay." Thereater, human trafficking of captured Africans would continue for hundreds of years.
