In the 1850s, white Francophones remained an intact and vibrant community in New Orleans. They maintained instruction in French in two of the city's four school districts (all served white students). In 1860, the city had 13,000 free people of color ("gens de couleur libres"), the class of free, mostly mixed-race people that expanded in number during French and Spanish rule. They set up some private schools for their children. The census recorded 81 percent of the free people of color as mulatto, a term used to cover all degrees of mixed race. Mostly part of the Francophone group, they constituted the artisan, educated and professional class of African Americans. The mass of blacks were still enslaved, working at the port, in domestic service, in crafts, and mostly on the many large, surrounding sugarcane plantations.
