For all of history's five millennia human timeline, most were ignorant of their true ancestral history, why empires conquered illiterate cultures. History was secret by virtue of illiteracy. A 15th-century European technology changed that. Printed books finally gave true voice to persecuted, erudite, self-thinking heretics. They, their schools, and their mass-produced books gave rise to modern thinking, new ideas, and literacy for the masses. Consequently, the world slowly began changing for the better. And it's because of literacy, two kinds of histories existed since the 16th-century - to maintain servitude by ignorance. Empires must maintain their illusions to survive at any cost!
