US Citizenship — Bill of Rights and Constitutional Amendments

The Constitution is the supreme law of the United States. Adopted in 1787 and ratified in 1788, it establishes the structure of the federal government, defines the rights and duties of citizens, and sets the relationship between the states and the federal government. The Supremacy Clause in Article VI states that the Constitution and federal laws made under it are 'the supreme law of the land,' meaning state laws cannot conflict with federal law on matters where the federal government has authority. The Bill of Rights consists of the first ten amendments to the Constitution; it is part of the Constitution, not separate from it. The Declaration of Independence (1776) is a foundational historical document but is not law. Federal statutes are valid only when they do not conflict with the Constitution.

The Constitution has three main functions. First, it sets up the government by establishing the three branches (legislative, executive, judicial) and how they interact. Second, it defines the government by specifying its powers, limits, and structure, including the relationship between federal and state governments. Third, it protects the basic rights of Americans through provisions throughout the document and especially through the Bill of Rights (the first ten amendments). The Constitution does not list all federal laws — those are passed by Congress under powers granted by the Constitution. The United States is not a monarchy; the Constitution explicitly prohibits titles of nobility. The United Nations was founded in 1945, more than 150 years after the Constitution was written.

The Constitution begins 'We the People of the United States, in Order to form a more perfect Union...' The opening phrase 'We the People' is the foundational statement of American democracy: the government's authority comes from the people, not from a king or any other source. This was a radical idea in 1787 when most countries were ruled by monarchs claiming divine right. The phrase is often cited in discussions of constitutional interpretation and civic identity. 'All men are created equal' is from the Declaration of Independence, not the Constitution. The Preamble continues to explain the purposes of the Constitution: justice, domestic tranquility, common defense, general welfare, and the blessings of liberty for ourselves and our posterity.

An amendment is a change or addition to the Constitution. Amendments allow the Constitution to evolve over time without being rewritten. The amendment process is intentionally difficult: an amendment must be proposed by two-thirds of both houses of Congress (or by a convention of two-thirds of state legislatures) and then ratified by three-fourths of the states. Since 1789, more than 11,000 amendments have been proposed but only 27 have been ratified. The first ten amendments, ratified in 1791, form the Bill of Rights. The most recent amendment, the 27th, was ratified in 1992. Federal laws are passed by Congress under powers granted by the Constitution but are not part of it. Treaties and executive orders are different categories of legal action.

The first ten amendments to the Constitution are collectively known as the Bill of Rights. Ratified in 1791, they were demanded by many state ratifying conventions as a condition of approving the Constitution. They protect individual rights including freedom of speech, religion, the press, the right to assemble, the right to bear arms, protection against unreasonable search and seizure, the right to due process, the right to a jury trial, protection against cruel and unusual punishment, and the principle that rights not listed are reserved to the people and the states. The Federalist Papers were essays written to argue for ratification of the Constitution. The Articles of Confederation were the first US governing document, replaced by the Constitution. The Emancipation Proclamation was issued by President Lincoln in 1863.

There are 100 US Senators — two from each of the 50 states. This is set by Article I of the Constitution, which gives each state equal representation in the Senate regardless of population. Senators serve six-year terms, and elections are staggered so that roughly one-third of the Senate is up for election every two years. The Senate has unique powers including ratifying treaties (two-thirds majority required), confirming presidential appointments, and trying impeachment cases. The 435 figure refers to members of the House of Representatives, which is based on state population. The composition of the Senate is one of the central compromises of the Constitution: it balances the population-based House with equal state representation in the upper chamber.

Senators serve six-year terms. The Constitution sets the term length and staggers elections so that one-third of the Senate is up for election every two years. This staggered system means the Senate never turns over completely in a single election, providing institutional continuity. There is no constitutional limit on how many terms a Senator may serve, and many Senators have served for decades. By contrast, members of the House of Representatives serve two-year terms with all seats up for election simultaneously, and the President serves four-year terms with a two-term limit set by the 22nd Amendment. The longer Senate term was designed to give Senators more independence from immediate political pressure than House members.

The House of Representatives has 435 voting members. This number was set by the Reapportionment Act of 1929 and has not changed since. Each state's number of representatives is based on its population as measured by the census every ten years. The Constitution requires at least one representative per state, so the least populous states (Wyoming, Vermont, Alaska, North Dakota, South Dakota) have one each, while California has 52. Representatives serve two-year terms and all 435 seats are up for election in every even-numbered year. The 538 figure refers to the Electoral College, which includes 435 representatives plus 100 senators plus 3 electors for the District of Columbia.

US Representatives serve two-year terms. The Constitution sets this short term because the framers wanted the House to remain closely accountable to the people. All 435 House seats are up for election in every general election (every even-numbered year). There is no constitutional term limit. The Senate's six-year terms, by contrast, were designed to insulate Senators from short-term political pressure. The President's four-year term sits between the two. The combination of staggered terms across the branches was intended to slow rapid political change and force compromise.

The President of the United States is elected for a four-year term. The 22nd Amendment, ratified in 1951, limits a person to being elected President twice, for a maximum of eight years (or up to ten years if they assumed the presidency mid-term and served less than two years of the previous President's term). Before the 22nd Amendment, there was no constitutional limit, though all Presidents had voluntarily followed George Washington's two-term precedent until Franklin D. Roosevelt was elected four times. The presidential election occurs on the first Tuesday after the first Monday in November of years divisible by four. The President-elect is inaugurated on January 20th of the following year.
