Equal protection under the law

The Equal Protection Clause is part of the Fourteenth Amendment to the United States Constitution. The clause, which took effect in 1868, provides that no state shall deny to any person within its jurisdiction "the equal protection of the laws".

A primary motivation for this clause was to validate the equality provisions contained in the Civil Rights Act of 1866, which guaranteed that all people would have rights equal to those of all citizens. As a whole, the Fourteenth Amendment marked a large shift in American constitutionalism, by applying substantially more constitutional restrictions against the states than had applied before the Civil War.

The meaning of the Equal Protection Clause has been the subject of much debate, and inspired the well-known phrase "Equal Justice Under Law". This clause was the basis for Brown v. Board of Education (1954), the Supreme Court decision that helped to dismantle racial segregation, and also the basis for many other decisions rejecting discrimination against people belonging to various groups.

The Equal Protection Clause itself applies only to state and local governments. However, the Supreme Court held in Bolling v. Sharpe (1954) that equal protection requirements apply to the federal government through the Due Process Clause of the Fifth Amendment.

The Equal Protection Clause is located at the end of Section 1 of the Fourteenth Amendment:

All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
