What actions did the First Continental Congress take?

The First Continental Congress was concerned mostly with
economic responses to British actions.

The First
Continental Congress was called largely in response to the Coercive Acts, which were
imposed by the British after the Boston Tea Party.  The Congress spent a great deal of
time considering how to respond.  They eventually decided to respond with an economic
boycott.  They voted to ban both importation of goods from Great Britain and exportation
of goods to Great Britain unless the British government agreed to their
demands.

This economic boycott of Great Britain was by far
the most important actual action taken by the Congress.  However, the Congress was
important simply by the fact that it met at all.  This was one of the first important
moves towards uniting the colonies and, eventually, creating a new
country.
