Zacoccia, a king of Mozambique who, according to the Lusiad (q.v.), received Vasco da Gama with welcome, believing him to be a Mohammedan, but conceived feelings of bitterest hatred to him when he discovered he was a Christian, and tried, but all in vain, to allure him to his ruin; the agent he employed to compass it failing, in his despair he took away his own life.
