Jean Lafitte, a French pirate, formed the Slavery Empire on Galveston Island. Two brothers, Jewish traders Joa and Morin de la Porta, sponsored him. They were known as Karankawa Traders and Supercargoes for Lafitte, who grew extremely wealthy while descimating the Indian population, who were all labeled as "African" or "Negro" slaves for the expanding cotton trade. On June 19, 1865, General Gordon Granger and his forces headed to Galveston, Texas, to proclaim General Orders No. 3 and that all slaves had been freed. Juneteenth came to be known and celebrated on June 19th.
