Europeans carried a hidden enemy to the Indians: new diseases. Native peoples of America had no immunity to the diseases that European explorers and colonists brought with them. Diseases such as smallpox, influenza, measles, and even chicken pox proved deadly to American Indians.
In 1975 one-third of American mothers with young children had to work outside their houses. Nowadays, the amount of mothers that work is the double. This means that two-third of American women leave their house and children to work. The fact that more women are working brought an increase in the demand of services related to housework such as cleaning and child care.
Most slaves were Muslims.
This is never mentioned in any U.S. slaves history, yet it's true.
Hope this helps! :D
