Plessy v. Ferguson: Digital HistoryIn 1890, Louisiana passed a law prohibiting people of different races from traveling together on trains. This law was one of many forms of segregation, formal and informal, that came to be known as Jim Crow (named after a minstrel song). A group of African American educators, lawyers, journalists, and civic leaders in New Orleans decided to test the law in court. At the time, New Orleans had the country's largest African American population. "This act," black leaders declared, "will be a license to the evilly disposed...to insult, humiliate and maltreat...those who have a dark skin."
