During the colonial period, American colonies were
typically ruled by governors who were appointed by the English government.  If the
governors had complete power, they would be able to do whatever they wanted to the
colonists.

However, the colonists did have the "power of
the purse."  The governors' salaries and many other things were paid for by taxes and
such that were imposed by assemblies in each colony.  The assemblies were made up of
people elected by the colonists.

This is, in effect, a
check on the power of the governors.  If the colonists really didn't like how the
governors were acting, they could just stop paying them.  In this way, the colonists
kept some control over the governors.
