Ancient Egyptian Empire
Ancient Egypt practiced human slavery and had brutal ways to deal with its laborers. Research shows if a worker got out of line, they would be whipped 100 times, stabbed five times, and then immediately sent back out to work. On top of that, malnutrition and disease were prevalent among commoners, including joint diseases from carrying heavy loads all day.
I'm not sure where or how, izismile gets his facts... well, not facts really, leftist propaganda more like it. As in, Confederates raping "millions" of African-American women and, too, the items you mention as well as many others. Columbus a 'conquistador'... seriously.
Post entertainment, entertaining pictures, etc., not skewed takes on history in support of a Howard Zinn view of the world.
