The Stamp Act Congress was held in New York City in1765. Delegates from 9 American Colonies gathered to respond to the Stamp Act Parliament passed. The Stamp Act taxed commercial or legal documents, licenses, newspapers, permits, pamphlets and even playing cards. It was not a heavy tax but if they let Parliament pass this tax, they would only have more in the future. "No taxation without representation" basically means the English colonies did not want to be taxed without their consent.
The First Continental Congress met in 1774 in Philadelphia to protest Britain's Intolerable Acts (Coercive Acts): 1. Boston Ports would be closed until compensation was met to the East India Tea Company for the Boston Tea Party.

3. Royal Officers would not be tried in colonial courts.
4. They legalized quartering of troops in public buildings and private homes.
