Final answer:
The correct chronological order for the events of Plessy v. Ferguson begins with Louisiana passing the Separate Car Act in 1890, followed by the Comité des Citoyens planning a challenge and Homer Plessy deliberately sitting in a segregated train car. Plessy's arrest and subsequent court cases culminated in the Supreme Court's 1896 decision that upheld the legality of 'separate but equal,' entrenching racial segregation in law.
Step-by-step explanation:
The events related to the case of Plessy v. Ferguson should be arranged in the following chronological order: First, Louisiana passes the Separate Car Act in 1890. Then, a group of black citizens joined with the East Louisiana Railroad Company to challenge this law, and Homer Plessy was chosen to break the law as part of a planned act of civil disobedience by the Comité des Citoyens (Citizens' Committee). Plessy bought a first-class train ticket and deliberately sat in the "whites only" section of the train, thereby defying the Separate Car Act. As a result, Plessy was arrested for riding in a "whites only" railroad car. After his initial conviction, Plessy appealed the decision, which made its way through the legal system. In 1896, the case reached the Supreme Court, where the justices upheld the previous decisions, effectively legitimizing the doctrine of "separate but equal." This ruling led to widespread legal segregation across the United States, affecting countless aspects of public life and reinforcing a system of racial discrimination that would persist for decades.
