Answer:
Declaration of Independence, Articles of Confederation, and Constitution
Explanation:
The colonists wanted to break away from Britain so they wrote the Declaration of Independence to express their anger. The Articles of Confederation was the first form of document that all the states ratified to create a government. The Constitution was the better form of government and was created after the Articles of Confederation failed. The Constitution was improved based on what worked and what didn't during the use of the Articles of Confederation.
The British thought colonists had to pay more taxes/cost for the French and Indian War. Parliament also wanted more control, so they did a series of acts (Coercive Act) that all ended into the Intolerable Act.
Hope that helped!
Perhaps the greatest contribution of Grant and Sherman (Grant being the leader of the Northern forces) was that they knew when not to fight--that is when to hold back--since the North's army greatly outnumbered that of the South.
