This decision gave the legal basis for racial segregation in the USA, forcing black Americans to study in schools only for blacks, to use special, reserved for them public places.

Plessy v. Ferguson, 163 U. S. 537 (1896), was a landmark decision of the U. S. Supreme Court issued in 1896. It upheld the constitutionality of racial segregation laws for public facilities as long as the segregated facilities were equal in quality - a doctrine that came to be known as "separate but equal".
