The United States Constitution is the supreme law of the United States and was drafted in 1787 following the inadequacies of the Articles of Confederation, which had governed the nation since its independence. The Constitutional Convention, held in Philadelphia, was attended by delegates from the various states who sought to create a stronger federal government while still protecting individual liberties and state sovereignty. The Constitution established a federal system with a separation of powers among the legislative, executive, and judicial branches. It also included checks and balances to ensure no single branch would dominate the government.
The Constitution was signed on September 17, 1787, but required ratification by nine of the thirteen states to become effective. This led to a series of debates between Federalists, who supported the Constitution, and Anti-Federalists, who feared it gave too much power to the federal government. To address these concerns and to ensure ratification, the Bill of Rights, comprising the first ten amendments, was introduced, guaranteeing fundamental rights and freedoms such as freedom of speech, religion, and the press, as well as protections against governmental abuses of power. These amendments were ratified in 1791.
The drafting of the Constitution was a response to the weaknesses of the Articles of Confederation, which lacked a strong central government. The ratification debates highlighted the tension between federal and state powers. The Bill of Rights was crucial in securing the Constitution's ratification by assuaging fears of an overly powerful central government and protecting individual liberties.
