or take Sundays off. Although the Code Noir authorized and codified cruel corporal punishment against slaves under certain conditions, it forbade slave owners to torture them or to separate families. It also demanded enslaved Africans receive instruction in the Catholic faith, implying that Africans were human beings endowed with a soul, a fact French law did not admit until then. It resulted in a far higher percentage of blacks being free in 1830 (13.2% in Louisiana compared to 0.8% in Mississippi). They were on average exceptionally literate, with a significant number of them owning businesses, properties, and even slaves. Other free people of colour, such as Julien Raimond, spoke out against slavery. The Code Noir also forbade interracial marriages, but it was often ignored in French colonial society and the mulattoes became an intermediate caste between whites and blacks, while in the British colonies mulattoes and blacks were considered equal and discriminated against equally. During the Age of Enlightenment, many philosophers wrote pamphlets against slavery and its moral and economical justifications, including Montesquieu in The Spirit of the Laws (1748) and Denis Diderot in the Encyclopédie. In 1788, Jacques Pierre Brissot founded the Society of the Friends of the Blacks (Société des Amis des Noirs) to work for the abolition of slavery. After the Revolution, on 4 April 1792, France granted free people of colour full citizenship. The slave revolt, in the largest Caribbean French colony of Saint-Domingue in 1791, was the beginning of what became the Haitian Revolution led by formerly enslaved people like Georges Biassou, Toussaint L'Ouverture, and Jean-Jacques Dessalines. The rebellion swept through the north of the colony, and with it came freedom to thousands of enslaved blacks, but also violence and death. In 1793, French Civil Commissioners in St. Domingue and abolitionists, Léger-Félicité Sonthonax and Étienne Polverel, issued the first emancipation proclamation of the modern world (Decree of 16 Pluviôse An II). The Convention sent them to safeguard the allegiance of the population to revolutionary France. The proclamation resulted in crucial military strategy as it gradually brought most of the black troops into the French fold and kept the colony under the French flag for most of the conflict. The connection with France lasted until blacks and free people of colour formed L'armée indigène in 1802 to resist Napoleon's Expédition de Saint-Domingue. Victory over the French in the decisive Battle of Vertières finally led to independence
