The Eighteenth Amendment resulted from a national effort to control the making, distribution, sale, and consumption of alcoholic beverages. Prohibition, called a “noble experiment” in a paraphrase of President Herbert Hoover’s explanation of its goals, was an attempt to control reckless and destructive personal behavior.

Initially, the legislatures of each state elected their U.S. senators. In a number of instances, disagreements between the two houses of a state legislature left Senate seats vacant for protracted periods.

In Article I, sections 2 and 9 the U.S. Constitution said that no direct taxes could be imposed unless made in proportion to the population, as measured by the census. This meant that rather than taxing individuals directly, Congress had to levy taxes in each state based on the state’s population.

The Fifteenth Amendment prohibits the use of race in determining who can vote. The last of the three Reconstruction Era amendments, ratified shortly after the Civil War, the Fifteenth Amendment sought to advance the civil rights and liberties of the freed slaves and other African Americans.

The right of privacy—the right to be left alone, as Justice Louis Brandeis once defined it—is fundamental to our understanding of freedom, but nowhere does the Constitution mention it. When Congress submitted the Bill of Rights to the people for ratification in 1789, privacy was not listed as a liberty that required protection from government.

Although it was created primarily to deal with the civil rights issues that followed the abolition of slavery, the Fourteenth Amendment has affected a broad range of American life, from business regulation to civil liberties to the rights of criminal defendants.

In 1863, President Abraham Lincoln issued the Emancipation Proclamation based on his war powers. It freed the slaves held within the Southern states that were in rebellion against the United States.

As the Electoral College was originally constituted, the candidate who received the most electoral votes became President and the runner-up became Vice President. With the rise of a two-party system, this meant that the President and Vice President might be chosen from different parties.

After the U.S. Supreme Court ruled in 1793 that two South Carolina men could sue and collect debts from the state of Georgia, states’-rights advocates in Congress proposed what became the Eleventh Amendment. This amendment specifically prohibits federal courts from hearing cases in which a state is sued by individuals from another state or country.

The Ninth Amendment offers a constitutional safety net, intended to make it clear that Americans have other fundamental rights beyond those listed in the Bill of Rights.

The Seventh and Eighth Amendments add to the Constitution’s protections for individuals in the judicial system.

Many legal observers consider the right to petition to be uninteresting. It has spurred no landmark cases, and the First Amendment’s language is plain and straightforward: Congress shall make no law abridging the “right of the people . . . to petition the Government for a redress of grievances.” It guarantees citizens the right to complain and ask officials to correct a problem or right a wrong, but where is the controversy in exercising this right? It is an obvious right in a democratic society.

The Sixth Amendment further specifies the protections offered to people accused of committing crimes. It allows the accused to have their cases heard by an impartial jury made up of people from the surrounding community who have no connection to the case.
