There were many causes of the American revolution. One of them was the Stamp Act.The Stamp Act was passed by the British Parliament on March 22, 1765. The new tax was imposed on all American colonists and required them to pay a tax on every piece of printed paper they used.

Another cause of the American revolution was the Proclamation of 1763.The proclamation acknowledged that Native Americans owned the lands on which they were then residing and white settlers in the area were to be removed.

The Boston Massacre was the killing of five colonists by British regulars on March 5, 1770. This picture was made as a false battle of actually how it was fought.
