Supremacy Clause in the context of "Territories of the United States"

The Constitution of the United States is the supreme law of the United States of America. It superseded the Articles of Confederation, the nation's first constitution, on March 4, 1789. Originally including seven articles, the Constitution defined the foundational structure of the federal government.

The drafting of the Constitution by many of the nation's Founding Fathers, often referred to as its framing, was completed at the Constitutional Convention, which assembled at Independence Hall in Philadelphia between May 25 and September 17, 1787. Influenced by English common law and the Enlightenment liberalism of philosophers like John Locke and Montesquieu, the Constitution's first three articles embody the doctrine of the separation of powers, in which the federal government is divided into the legislative, bicameral Congress; the executive, led by the president; and the judiciary, within which the Supreme Court has apex jurisdiction. Articles IV, V, and VI embody concepts of federalism, describing the rights and responsibilities of state governments, the states in relationship to the federal government, and the process of constitutional amendment. Article VII establishes the procedure used to ratify the constitution.

In the United States of America, each state has its own written constitution. The Supremacy Clause of the Constitution of the United States (Article VI, Clause 2) establishes that the Constitution, federal laws made pursuant to it, and treaties made under the authority of the United States, constitute the "supreme Law of the Land", and thus take priority over any conflicting state laws. It provides that state courts are bound by, and state constitutions subordinate to, the supreme law.

The Tenth Amendment to the United States Constitution (part of the Bill of Rights) provides that "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." The Guarantee Clause of Article 4 of the Constitution states that "The United States shall guarantee to every State in this Union a Republican Form of Government." These two provisions indicate states did not surrender their wide latitude to adopt a constitution, the fundamental documents of state law, when the U.S. Constitution was adopted.

The Constitution of the Commonwealth of Puerto Rico (Spanish: Constitución del Estado Libre Asociado de Puerto Rico, lit. 'Constitution of the Free Associated State of Puerto Rico') is the primary organizing law for the unincorporated U.S. territory of Puerto Rico, describing the duties, powers, structures, and functions of the local government of Puerto Rico and its relation with the U.S. in nine articles. Established under the Puerto Rico Federal Relations Act of 1950, it was approved by the residents of the archipelago and island in a constitutional referendum on March 3, 1952, ratified by the U.S. Congress as per Pub. L. 82–447 on July 3, 1952, and proclaimed into effect by Governor Luis Muñoz Marín on July 25, 1952, which is celebrated as Constitution Day. As the constitution of a U.S. territory, it is bound by the U.S. Constitution.

The Constitution of Puerto Rico established the Commonwealth of Puerto Rico, which succeeded the insular government that operated under two organic acts: the Foraker Act from 1900 to 1917 and the Jones–Shafroth Act from 1917 to 1952. With the ratification of the constitution in 1952, the full authority and responsibility for the local government of Puerto Rico was vested in the residents of Puerto Rico, resulting in complete self-governance within the archipelago and island.
