There are, of course, many such sources that were relevant at various times before 1750. Some sources include:
- "Race." There were conflicts between the Europeans and the Native Americans almost as soon as the settlers arrived. There was also, to some degree, conflict between blacks and whites. These included such things as the New York City Slave Rebellion of 1712 and the Stono Rebellion of 1739.
- Religion. In some parts of America, there were conflicts between religious groups. A good example of this came in New England where there were conflicts between the dominant Puritans and people (within and outside of the Puritan religion) who had different beliefs.
- Class. We see examples of class conflict in the colonies before 1750. The best-known major example of this was Bacon's Rebellion in Virginia in 1676. This rebellion was largely based on the grievances of the poorer backwoods people against the elites who ran the colony.
