No representatives for the taxes

After the seven year war there was a huge dept that had to be paid. To do so, the parliament decided to increase the taxes. Colonist disliked that a lot.

Colonists thought that the stamp act hid conspiracy from the British to destroy American liberty. They also thought it was not fair since there were no representatives of the parliament in the colonies. They had to send representatives across the Atlantic. Since the distances were very long it would take lots of time for the instructions to arrive from a place to another.

America wanted to put their own taxes since they were so important, and wanted the parliament’s approval.

Essentially, "No taxation without representation" really meant, "No taxation by Parliament. No representation in Parliament. Let us run our own affairs."
