By the 1770s, many colonists were angry because they did not have self-government. This meant that they could not govern themselves and make their own laws. They had to pay high taxes to the king. They felt that they were paying taxes to a government where they had no representation.
They placed tax on almost all of their products which led to many people falling into poverty. Even though the colonists were descended from people in England, they were treated terribly. The rules were absurd, one particular one which stated that soldiers could stay in any colonists' house and the colonist had to allow the solider access to their home.
