Beep. Circle takes the square. France and Britain had abolished slavery a couple of decades earlier. And they managed to do it without slaughtering nearly a million people.
If you read some of my other posts, I went on to explain that the British only changed the names of slavery to servitude, indenture, and coolie.
They did not use blacks, they used Indians, Irish and anyone else they occupied.
Their so called abolition did not apply to their colonies. They also had a ten year grace period.
