The Constitution is the highest law of the United States of America. It contains a three branched system of national government consisting of the legislative, judicial (headed by the Supreme Court) and executive (headed by the President) arms of government. In addition to this it formed a bicameral Congress with an upper and lower house. It was adopted by the Constitutional Convention and ratified by each of the thirteen American states. . The Constitution created a strong federal government which was able to solve the economic, political and social problems of the nation which were prevalent under the Article of Confederation. This is due to the federal government’s power to represent all the states and raise taxes. The first amendment of the Constitution was the Bill of Rights which acted as a document to safeguard the rights of all Americans. Through this document the Americans fought to retain their birthrights to English liberty under the law. The Bill of Rights which was  based on the Virginian Declaration of Rights was ratified in 1791 and led to 10 amendments in the Constitution. It was defined as the cornerstone of American civil liberty.
