One of the most significant developments of the first half of the 19th century was the migration of settlers from the older states of the South and particularly from South Carolina and the Edgefield District to the newly opened areas of Georgia, Florida, Alabama, Mississippi, Louisiana and Texas. Among the pioneers in this movement were two Edgefieldians, William Barrett Travis and James Butler Bonham, who entered the fight for Texas Independence from Mexico and who died at the Alamo in 1836.
