"Louisiana enacted the Separate Car Act which required separate railway cars for blacks and whites. In 1892 Homer Plessy – who was seven-eighths Caucasian – agreed to participate in a test to challenge the Act. He was solicited by the Comite des Citoyens (Committee of Citizens) a group of New Orleans residents who sought to repeal the Act. They asked Plessy who was technically black under Louisiana law to sit in a "whites only" car of a Louisiana train."
