Mr. Scarbrough, explains this very very very well!
The reason why Britain's American colonies were most angered by the taxes imposed on them by Britain was because e the colonist felt like they had no say in the taxation.
The thirteen colonies protested many things. They did not like any of the laws or taxes that Britain imposed on them.
Mercantilism was the basic policy imposed by Britain on its colonies. The colonies were captive markets for British industry, and the goal was to enrich the mother country.
causation
The Navigation Acts were a series of laws imposed by Britain on its American colonies. Its main purpose was to restrict colonial trade in order to prevent the colonies from smuggling goods from other countries. All goods that were traded with the colonies had to be sent to a British port before being sent to the colonies. That way, the British could tax the goods and they could make sure that nothing was being smuggled into the colonies. The colonists were unhappy with the laws and tensions quickly emerged.
Causation
Britain had not imposed any tariffs or taxes on the Colonies. After the global war called the 7 year War (French and Indian War in North America) England imposed taxes on the Colonies to pay for the war effort. This led to the colonial rebellion.
The British felt that they had protected the colonies from the French and that the colonists were British so they should help pay for the war.
The Declaratory Act or the American Colonies Act of 1766 was enacted by Parliament and imposed on the American colonies. It was developed after the Stamp Act of 1765 was repealed. The Act was made to establish Britain's dominance over the colonies.
"Abuse" is probably not the right word. And it was not the King in person by then who ruled Britain and its colonies, it was the British government and Parliament. What happened was that a couple of taxes were imposed that were highly unpopular amongst the colonists, who then unsuccessfully demanded that taxes should and could only be imposed on them if they were adequately represented in the British Parliament. One of the unpopular measures was that Britain had left a sizable army in the colonies after the French-Indian war and levied a tax on the colonies to pay for its upkeep. Britain held that the army was there for the colonies' protection in case the hostilities were renewed, so it was only right that they should pay for it. The colonies saw the army as an occupation force and considered having to pay for it as adding insult to injury.
All three of these acts imposed British rule over the American colonies. The Proclamation Line declared Britain the ruler of all transactions west of the Appalachians. The Stamp Act and Townshend Acts imposed internal taxes on the colonies.
After the French and Indian War, Great Britain had a massive debt. The Stamp Act was an act placed on paper goods to be payed by the colonies. This tax, and others, was Englands attempt to pay off its debt.
