With a relatively large educated black (including a self-described "Creole" or mixed-race) population that had long interacted with the white population, racial attitudes were comparatively liberal for the Deep South. For example there was the 1892 New Orleans general strike that began on November 8, 1892. But, like other southern cities and towns, African Americans were barred from a range of employment possibilities, including police officers, and firefighters. No black child was allowed an education at a public high school in the city. From hotels, parks, museums and restaurants, black citizens were denied access through a rigid system of Jim Crow, but some in the city objected to the State of Louisiana's attempt to enforce strict racial segregation, and hoped to overturn the law with a test case in 1892. The case found its way to the U.S. Supreme Court in 1896 as Plessy v. Ferguson. This resulted in upholding segregation, which would be enforced with ever-growing strictness for more than half a century.
