which traces the beginning of slavery from its roots in the British Empire

No matter who or why slavery came to and exited in America. Slavery did not have its roots in the British Empire. Slavery has been around since man.

Ding ding ding ding, we have a winner.
every religion, race etc has been slaves at tone time or another.
Today there are more slaves throughout the world than ever before.
But as you say, slavery has been around since the dawn of man.
