Slavery in the colonial United States in the Caribbean: Guadeloupe and especially Saint-Domingue.) After the port of New Orleans was founded in 1718 with access to the Gulf Coast, French colonists imported more African slaves to the Illinois Country for use as agricultural or mining laborers. By the mid-eighteenth century, slaves accounted for as many as a third of the limited population in that rural area. Slavery was much more extensive in colonial Louisiana, where the French developed sugar cane plantations along the Mississippi river. Slavery was maintained during the French (1699 – 1763, and 1800 – 1803) and Spanish (1763 – 1800) periods of government.
France in the Middle Ages the north of France, the "langue d'oïl" like Picard, Walloon, and Francien, were influenced by the Germanic languages spoken by the Frankish invaders. From the time period of Clovis I on, the Franks extended their rule over northern Gaul. Over time, the French language developed from either the Oïl language found around Paris and Île-de-France (the Francien theory) or from a standard administrative language based on common characteristics found in all Oïl languages (the lingua franca theory). "Langue d'oc", the languages which use "oc" or "òc" for "yes", is the language group in the south of France and northern Spain.
