On February 23, 1807, the British parliament passed a bill banning the nation’s slave trade. In these two articles, we’ll explore the lives of two men and one song that played a significant role in that effort.

But he lost his mother when he was six years old, and at the age of eleven, followed his sea-captain father to the sea.
