## Step 1<br />The Supreme Court case Plessy v. Ferguson took place in 1896. This case was a significant event in the history of the United States, as it established the principle of "separate but equal" facilities for different races.<br />## Step 2<br />The case arose from an incident where Homer Plessy, who was seven-eighths white and one-eighth black, deliberately violated Louisiana's Separate Car Act by sitting in a "whites-only" railroad car. This act mandated racial segregation in public facilities.<br />## Step 3<br />The Supreme Court's decision in this case was that the Louisiana law did not violate the 14th Amendment, which guarantees equal protection under the law. The Court's reasoning was that as long as the separate facilities for different races were equal, they did not violate the 14th Amendment.<br />## Step 4<br />This decision effectively provided a legal justification for segregation laws, which were also known as Jim Crow laws. These laws mandated racial segregation in all public facilities, leading to widespread discrimination against African Americans.
