What are the various sources of cultural conflict in American history before 1750?

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.
