Ratification is the formal approval process of an agreement or document, often involving a vote by a governing body. In the context of the United States, ratification is crucial for treaties and constitutional amendments, requiring a specific majority to become effective. For example, the U.S. Constitution was ratified by the states after extensive debate and discussion. Each state held conventions to consider the document, and once nine states approved it, the Constitution became the law of the land. Ratification ensures that the voices of the representatives or citizens are heard in the decision-making process.
