Answer:
The main reason the colonists were angry was because Britain had rejected the idea of 'no taxation without representation'. Almost no colonist wanted to be independent of Britain at that time. Yet all of them valued their rights as British citizens and the idea of local self-rule. They considered the Stamp Act to be the worst in a series of violations of these rights.
Explanation:
There are several different experiences that unified the colonists in British North America during the 18th century. Here is a list of just a few:
1) Implementation of taxes by the British government- Taxes like the Stamp Act, Tea Act, and Sugar act are just a few examples of laws that united American colonists in anger against the British government. These colonists felt these taxes were unfair, as they were implemented without hearing the opinion of colonists. After this, the rallying cry became "no taxation without representation."
2) Boston Tea Party- This destruction of British tea by American colonists showed their unity against the unfair Tea Act implemented by the British government. Colonists all over the 13 colonies supported this action, as it made a point to the British government that colonists were displeased with the laws being passed in their society.
I wander thro' each charter'd street,
Near where the charter'd Thames does flow.
And mark in every face I meet
Marks of weakness, marks of woe.
In every cry of every Man,
In every Infants cry of fear,
In every voice: in every ban,
The mind-forg'd manacles I hear
How the Chimney-sweepers cry
Every blackning Church appalls,
And the hapless Soldiers sigh
Runs in blood down Palace walls
But most thro' midnight streets I hear
How the youthful Harlots curse
Blasts the new-born Infants tear
And blights with plagues the Marriage hearse
