The Articles of Confederation prevented the government from taxing, forming a defense, and provided no justice and law-making system. The Constitution formed a permission to tax and a tax regulation, allowed congress to form a defense system, and formed a bicameral legislative system. The Constitution also established the court systems and the supreme courts.
Theodore Roosevelt won the Nobel Peace Prize in 1906 for his work on the Treaty of Portsmouth. This treaty ended up ending the war between the Japanese and the Russians.
