For the first 100+ years of the colonies, Great Britain mostly left the colonists to their own devices. However, that suddenly changed.
The Tea Act
Colonial assemblies were elected to pass laws and control how tax money was spent. White, land-owning men could vote.
Declaratory Act
In 1765, Britain passed an act that made all printed items (newspapers, pamphlets, etc) require a stamp. The colonists were enraged because they did not have a say in this and saw it as "taxation without representation".
Declaration of Independence
We hold these truths to be self evident...
The Tea Act was an act passed in 1773 forcing the colonies to get their tea from a specific tea company owned by the British. Although this lowered the price, colonists thought it was a trick and in response on December 16, 1773, Sons of Liberty dressed as Indians dumped 342 chests of tea into Boston Harbour.
The Declaratory Act was an act passed in 1766 by Parliament stating that it had complete power over the colonies and affirmed Great Britain's right to pass laws that affected the colonists.
We can now control you!
In July of 1776, Thomas Jefferson used John Locke's ideas to write the first draft of the Declaration of Independence. He listed the King's acts of tyranny and states that the colonies are now free and independent states.
