The Industrial revolution transformed families profoundly. As the specialization of labor inside the factories took place, the lives of working-class families also experienced a division in distinctive roles. Work and home life grew clearly separated, as men were supposed to earn money for the family and women had to take care of the home and had their economic role decay.
The American Revolution had profound effects on the institution of slavery. Several thousand slaves won their freedom by serving on both sides of the War of Independence. As a result of the Revolution, a surprising number of slaves were manumitted, while thousands of others freed themselves by running away.
