Well over one million whites were enslaved in North Africa between the 16th and 19th centuries, most of them abducted and sold by Muslim pirates. Africans were raiding Europe for slaves for hundreds of years. The school system has totally erased this fact from history.
Of course white people were enslaved in other parts of Africa too, and across the world for centuries. Including in North America where white “servants” were shipped to the colonies by the thousands.
Slavery in America didn’t begin in 1619. White children were being kidnapped and sold into servitude in the colonies before that. And of course slavery existed in the Americas for hundreds of years prior to Europeans ever setting foot here. Indian tribes all practiced slavery.
