The crew of the British slave ship Zong murders 54 Africans by dumping them into the sea to claim insurance, beginning the Zong massacre.

Insurance is a means of protection from financial loss in which, in exchange for a fee, a party agrees to compensate another party in the event of a certain loss, damage, or injury. It is a form of risk management, primarily used to protect against the risk of a contingent or uncertain loss.

The Zong massacre was a mass killing of more than 130 enslaved African people by the crew of the British slave ship Zong over several days from 29 November 1781. The William Gregson slave-trading syndicate, based in Liverpool, owned the ship as part of the Atlantic slave trade. As was common business practice, they had taken out insurance on the lives of the enslaved Africans as cargo. According to the crew, when the ship ran low on drinking water after a series of navigational errors, the crew threw enslaved Africans overboard.

November 29 is the 333rd day of the year in the Gregorian calendar; 32 days remain until the end of the year.
