Foundations of American Government Timeline

Congress adopted the Articles of Confederation as the first written framework for the United States. The document created a league of states with a weak central government, limited taxing power, and no independent executive or national judiciary.

The Treaty of Paris ended the Revolutionary War and recognized the independence of the United States. It established national boundaries to the Mississippi River and gave the new republic an international legal foundation.

The Land Ordinance of 1785 created a systematic rectangular survey of western lands and provided for their sale and settlement. Its reservation of sections for schools linked territorial administration to public education and established a durable federal land policy.

Massachusetts farmers, many facing debt and foreclosure, resisted state courts and tax collection in Shays' Rebellion. The uprising exposed weaknesses in state and Confederation governance and strengthened calls for a more capable national government.

Delegates meeting at Annapolis called for a broader convention to address problems with interstate commerce and the Articles of Confederation. Their recommendation led directly to the Philadelphia Convention of 1787.

Delegates met in Philadelphia to revise the Articles of Confederation but eventually designed an entirely new constitutional system. Their debates addressed representation, federalism, executive power, judicial authority, slavery, and the balance between national and state governments.

The convention counted three-fifths of enslaved people for purposes of congressional representation and direct taxation. The compromise strengthened the political power of slaveholding states while embedding slavery in the constitutional design.

The Northwest Ordinance organized the territory north and west of the Ohio River and established a path from territorial status to statehood. It protected certain civil liberties, encouraged public education, and prohibited slavery in the territory.

Alexander Hamilton, James Madison, and John Jay published essays under the name Publius to advocate ratification of the Constitution. The essays remain a major source for interpreting the framers' arguments about federalism, faction, separation of powers, and republican government.

Delaware became the first state to ratify the Constitution. Its unanimous convention vote provided an early boost to the national ratification campaign and demonstrated that a state could accept the new framework without amendments.

New Hampshire became the ninth state to ratify the Constitution, satisfying the document's requirement for approval by nine states. Ratification made the new federal government legally operative, although major states including Virginia and New York had not yet joined.

The constitutional government formally began operations after ratification by the required states. The First Congress assembled, establishing the institutional framework that replaced the Confederation government.

George Washington took the presidential oath in New York City, becoming the first president under the Constitution. His inauguration established important precedents for executive authority, public ceremony, and the peaceful transfer of constitutional office.

The Judiciary Act of 1789 created the federal court system required by Article III. It established district and circuit courts, organized the Supreme Court, and defined the jurisdiction and responsibilities of federal judges and legal officers.

Treasury Secretary Alexander Hamilton's program addressed national and state debts, created a national bank, and imposed federal financial measures. The debates over these policies clarified competing interpretations of implied powers and the scope of federal authority.

The first ten amendments to the Constitution were ratified as the Bill of Rights. They protected freedoms of religion, speech, press, assembly, and petition and recognized safeguards involving criminal procedure, due process, arms, and reserved powers.

The Eleventh Amendment limited the ability of individuals to sue states in federal court. It emerged from concerns about state sovereignty and helped define the constitutional relationship between state governments and federal judicial power.

The Supreme Court's decision in Marbury v. Madison established the principle of judicial review. Chief Justice John Marshall held that courts could invalidate laws conflicting with the Constitution, making the judiciary a central interpreter of constitutional limits.

The United States acquired the Louisiana Territory from France, dramatically expanding the nation's territory. The purchase tested constitutional arguments about executive treaty power, territorial governance, and the federal government's authority to incorporate new lands.

In McCulloch v. Maryland, the Supreme Court upheld Congress's authority to create a national bank under the Necessary and Proper Clause and rejected Maryland's tax on it. The ruling strengthened federal supremacy and established a broad interpretation of implied congressional powers.

The Missouri Compromise admitted Missouri as a slave state and Maine as a free state while restricting slavery in much of the Louisiana Territory north of latitude 36°30′. It temporarily preserved sectional balance in Congress while exposing the constitutional crisis over slavery.

Gibbons v. Ogden interpreted the Commerce Clause to give Congress broad authority over interstate navigation and commerce. The decision limited conflicting state monopolies and expanded the constitutional foundation for national economic regulation.

The Fourteenth Amendment established national citizenship and required states to provide due process and equal protection of the laws. It transformed the constitutional relationship between citizens and state governments and became the basis for many later civil-rights decisions.

The Fifteenth Amendment prohibited denying the right to vote on the basis of race, color, or previous condition of servitude. It constitutionalized a major expansion of political citizenship after the Civil War, although discriminatory enforcement continued for decades.

The Nineteenth Amendment prohibited denying the vote on account of sex. It completed the constitutional basis for women's suffrage nationwide after decades of organizing, state campaigns, and national advocacy.
