1. disease brought by colonists was a major factor. Kills millions
2. violent conflicts between the colonists and/or British forces against the natives
3. The westward expansion (there's a special name for it) Colonists kept colonizing deeper and deeper into the mainland until reaching the western sea coast. killing 10's of thousands on the way there

The system of checks and balances makes sure that one branch of gov. Doesn't get more powerful than the other by giving different powers to different branches. Like a certain branch can't do something without the "thumbs up" from the other branch. For example, the Executive Branch can veto bills from the Legislative Branch, but the Legislative Branch can override the veto. Hopefully that helped!!
