Answer:
In 1783 in Britain, and most of the world, slavery was an accepted and legal practice.
Sick slave being thrown overboardIn that year, a case was heard before the British courts. The insurer of the slave ship Zong, which carried African slaves from Africa to the Americas, refused to pay a claim for “lost cargo”. That lost cargo was more than 100 sick slaves that had been thrown overboard by the ship’s captain, so that their value could be claimed against the insurers. If the slaves had died of natural causes (their sickness), no claim could be brought against the insurers. The insurers won their case. Efforts to bring murder charges against the ship owners failed. The slaves were not human beings they were goods.
