Digital History
"The first true slave society in history emerged in ancient Greece between the 6th and 4th centuries. "
"Slavery never disappeared from medieval Europe. While slavery declined in northwestern Europe, it persisted in Sicily, southern Italy, Russia, southern France, Spain, and North Africa. Most of these slaves were "white," coming from areas in Eastern Europe or near the Black Sea."
and after all these horrible slavery accounts, finally and fortunately for race card players, it were people from Africa:
"When Europeans began to colonize the New World at the end of the 15th century, they were well aware of the institution of slavery. As early as 1300, Europeans were using black and Russian slaves to raise sugar on Italian plantations. During the 1400s, decades before Columbus's "discovery" of the New World, Europeans exploited African labor on slave plantations built on sugar producing islands off the coast of West Africa."
So there was a huge, huge scale of white slavery before the black colonial era slaves.
This piece of history comes from an official education textbook site for schools in the US.
But it looks like they deliberately leave out that part during the actual education. Because nobody seems to know this in the US somehow. The collective memory only goes back 200 years max, like the world is 200 years old.
Ignorance is bliss, right brasshat?
