In which year was the Constitution ratified?

The Constitution of the United States was ratified in 1788, which is significant as it marked the official adoption of the nation's framework of government. Ratification involved a series of debates among the states to discuss and ultimately approve the proposed Constitution. The process began with the Constitutional Convention in Philadelphia in 1787, where the document was drafted. However, the actual ratification process continued into 1788, with the ninth state, New Hampshire, officially adopting it on June 21 of that year, thereby allowing the Constitution to take effect. Understanding this timeline is essential as it highlights the importance of both the drafting and the ratification process in establishing the U.S. government and reflects the principles of federalism and representative democracy.
