Historical & Foundational Concepts

The legal right to vote in public elections. Suffrage is one of the most fundamental rights in a democracy, as it gives citizens a direct say in who represents them and how they are governed. The history of suffrage in the United States is a long story of expansion, with the right to vote gradually extended to groups that were initially excluded, often only after sustained political organizing and protest.

The principle that all adult citizens have the right to vote, regardless of race, gender, property ownership, religion, or other characteristics. True universal suffrage was not achieved in the United States in a single moment but through a series of constitutional amendments, court decisions, and legislation passed over more than two centuries.

The movement and eventual achievement of women's right to vote. After decades of organizing, protest, and advocacy, women in the United States gained the constitutional right to vote with the ratification of the 19th Amendment in 1920. The suffrage movement involved a broad coalition of activists and remains one of the most significant civil rights campaigns in American history.

A landmark federal law passed in 1965 that prohibited discriminatory voting practices that had been used to disenfranchise Black Americans and other minority voters, particularly in the South. The law banned literacy tests, provided for federal oversight of elections in areas with a history of discrimination, and transformed voter access across the country. Its passage followed years of civil rights activism and the events of Bloody Sunday in Selma, Alabama.

The amendment to the U.S. Constitution, ratified in 1920, that granted women the right to vote. It states that the right of citizens to vote shall not be denied or abridged on account of sex. Its ratification was the culmination of more than 70 years of organized advocacy by the women's suffrage movement.

The amendment to the U.S. Constitution, ratified in 1971, that lowered the voting age from 21 to 18. It was passed in large part in response to the argument that young Americans who were old enough to be drafted and serve in the military should also have a voice in the elections that determined who led the country.

The gathering of delegates from the American states held in Philadelphia in 1787, at which the current U.S. Constitution was drafted. Originally convened to revise the Articles of Confederation, the delegates ultimately decided to write an entirely new governing document. The Constitution produced at that convention has served as the supreme law of the United States ever since, though it has been amended 27 times.

A formal change or addition to the U.S. Constitution. Amendments allow the Constitution to be updated over time to reflect evolving values, correct injustices, or address issues not anticipated by the original framers. The amendment process is intentionally difficult, requiring approval by two-thirds of both chambers of Congress and ratification by three-fourths of the states. There have been 27 amendments since the Constitution was ratified.

The formal process by which a proposed law, treaty, or constitutional amendment is officially approved and adopted. In the United States, ratification of constitutional amendments requires approval by three-fourths of state legislatures or state conventions. The term is also used to describe a state's formal approval of the original Constitution during the founding period.

The first ten amendments to the U.S. Constitution, ratified in 1791, which guarantee specific rights and freedoms to individuals and limit the powers of the federal government. The Bill of Rights protects freedoms including speech, religion, the press, assembly, the right to a fair trial, and protection from unreasonable searches and seizures. Its adoption was a condition demanded by several states before they would agree to ratify the Constitution.

The document adopted by the Continental Congress on July 4, 1776, declaring the thirteen American colonies independent from British rule. Written primarily by Thomas Jefferson, it articulates foundational principles of democratic governance, including the idea that all people are created equal and that governments derive their just powers from the consent of the governed. While not a legally binding governing document, the Declaration remains one of the most influential political texts in world history.

The group of political leaders, statesmen, and thinkers who played a central role in the American Revolution and the creation of the United States government. The term most commonly refers to figures like George Washington, Thomas Jefferson, James Madison, Alexander Hamilton, Benjamin Franklin, and John Adams, who helped draft and ratify the Declaration of Independence, the Constitution, and the Bill of Rights. Their writings and debates continue to shape how Americans interpret the country's governing principles.

The first governing document of the United States, ratified in 1781, which established a loose alliance of the thirteen original states. Under the Articles, the national government had very limited powers: it could not levy taxes, regulate commerce, or enforce its own laws. The weaknesses of the Articles ultimately led to the Constitutional Convention of 1787 and the replacement of the Articles with the current U.S. Constitution.

The 13th, 14th, and 15th Amendments to the U.S. Constitution, ratified between 1865 and 1870 in the aftermath of the Civil War. The 13th Amendment abolished slavery, the 14th Amendment granted citizenship and equal protection under the law to all persons born or naturalized in the United States, and the 15th Amendment prohibited denying the right to vote based on race, color, or previous condition of servitude. These amendments fundamentally reshaped the relationship between the federal government and individual rights.

A fee that was required to be paid in order to register to vote or cast a ballot. Poll taxes were used extensively in Southern states after Reconstruction as a tool to prevent Black Americans and poor white voters from participating in elections. They were effectively banned for federal elections by the 24th Amendment in 1964 and prohibited in all elections by the Supreme Court shortly after.

An exam that some states required voters to pass before being allowed to register or vote. Though they appeared neutral on their face, literacy tests were administered selectively and used as a deliberate tool to disenfranchise Black voters throughout the South. They were effectively outlawed by the Voting Rights Act of 1965.

State and local laws enacted primarily in the Southern United States between the end of Reconstruction and the mid-1960s that enforced racial segregation and systematically denied Black Americans equal rights. Jim Crow laws governed virtually every aspect of public life, including voting, education, transportation, and housing. They were dismantled through a combination of civil rights legislation and Supreme Court decisions, most significantly the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

The broad social and political movement, most active from the mid-1950s through the late 1960s, that fought to end racial segregation, discrimination, and disenfranchisement in the United States. Led by figures including Martin Luther King Jr., Rosa Parks, John Lewis, and many others, the movement used nonviolent protest, legal challenges, and political organizing to secure landmark legislation including the Civil Rights Act of 1964 and the Voting Rights Act of 1965.

Any effort, whether through law, policy, or practice, to prevent eligible voters from registering, casting a ballot, or having their vote counted. Voter suppression has taken many forms throughout American history, from poll taxes and literacy tests to more contemporary practices like aggressive voter roll purges, polling place closures, and strict identification requirements. Understanding the history and current forms of voter suppression is essential to protecting the right to vote.
