Forcing people to pay taxes when they have had no say in making the law that created the tax. American colonies were angry about paying taxes that were passed by the British Parliament because they had no representatives that voted on the tax. This proclamation prevented many colonists from moving west onto the land that Britain won in the war. It was done by Britain to allow the Native Americans to keep the land and stop attacking the settlers who wanted to move there.
