The post-Revolutionary period was defined by the limitations of the Articles of Confederation, which created a weak central government unable to tax, regulate trade, or enforce laws. Its inability to address issues like Shays’ Rebellion—where farmers in Massachusetts protested unpaid debts and land foreclosures—exposed serious flaws in the system. The Constitutional Convention of 1787 began as a fix to these problems but instead drafted a new Constitution with stronger federal powers. Key compromises, such as the Three-Fifths Compromise and the establishment of a process for statehood through the Northwest Ordinance, helped unify the states. The Constitution introduced foundational principles like federalism, checks and balances, and popular sovereignty. Though debates between Federalists and Anti-Federalists persisted, the inclusion of the Bill of Rights in response to concerns about individual liberties secured broader support. Ultimately, nine states ratified the Constitution, marking the beginning of a new republic with a more effective and balanced government. This transition from a fragile wartime alliance to a structured national system laid the foundation for U.S. political development in the 19th century.
