After the French-Indian War Louisiana was ceded to Spain in the Treaty of Paris of 1763. With this change in leadership over the region, Madi Gras celebration began to be put to a halt. People of color were prohibited from wearing masks, feathers, and attending night time balls, all actions indicative of Mardi Gras celebrations.
