James "Jim" Bowie (pronounced  BOO-ee) (c. 1796 - March 6, 1836) was a 19th-century American pioneer, who played a prominent role in the Texas Revolution, culminating in his death at the Battle of the Alamo. Stories of him as a fighter and frontiersman, both real and fictitious, have made him a legendary figure in Texas history and a folk hero of American culture. Born in Kentucky, Bowie spent most of his life in Louisiana, where he was raised and where he later worked as a land speculator. His rise to fame began in 1827 on reports of the Sandbar Fight.

Shortly before the senior Bowie died circa 1820, he gave ten slaves as well as horses and cattle to both James and Rezin. For the next seven years, the brothers worked together to develop several large estates in Lafourche Parish and Opelousas. Louisiana's population was growing rapidly, and the brothers hoped to take advantage of its rising land prices through speculation. Without the capital required to buy large tracts, they entered into a partnership with pirate Jean Lafitte in 1818 to raise money. By then, the United States had outlawed the importation of slaves, and most southern states allowed anyone who informed on a slave trader to receive half of what the imported slaves would earn at auction as a reward. Bowie made three trips to Lafitte's compound on Galveston Island. On each occasion, he bought smuggled slaves and took them directly to a customhouse to inform on his own actions. When the customs officers offered the slaves for auction, Bowie purchased them and received back half the price he had paid, as allowed by the state laws. He then could legally transport the slaves and resell them at a greater market value in New Orleans or areas farther up the Mississippi River. Using this scheme, the brothers collected $65,000 to be used for their land speculation.  In 1825, the two brothers joined with their younger brother Stephen to buy Acadia Plantation near Thibodaux. Within two years, they had established the first steam mill in Louisiana to be used for grinding sugar cane. The plantation became known as a model estate, but on February 12, 1831, they sold it and 65 slaves for $90,000. With their profits, James and Rezin bought a plantation in Arkansas.  Bowie and his brother John were involved in a major court case in the late 1820s over land speculation. When the United States purchased the Louisiana Territory in 1803, it promised to honor all former land grant claims, and for the next 20 years efforts were made to establish who owned what land. In May 1824, Congress authorized the superior courts of each territory to hear suits from those who claimed they had been overlooked. The Arkansas Superior Court received 126 claims in late 1827 from residents who claimed to have purchased land in former Spanish grants from the Bowie brothers. Although the Superior Court originally confirmed most of those claims, the decisions were reversed in February 1831 after further research showed that the land had never belonged to the Bowies and that the original land grant documentation had been forged. The U.S. Supreme Court upheld the reversal in 1833. When the disgruntled purchasers considered suing the Bowies, they discovered that the documents in the case had been removed from the court; left without evidence, they declined to pursue a case.
