title: Demopolis, Alabama
context: Organizing themselves first in Philadelphia, French expatriates petitioned the U.S. Congress to sell them property for land to colonize. Congress granted approval by an act on March 3, 1817 that allowed them to buy four townships in the Alabama Territory at $2 per acre, with the provision that they cultivate grape vines and olive trees. Following advice obtained from experienced Western pioneers, they determined that Alabama would provide a good climate for cultivating these crops.  By July 14, 1817, a small party of pioneers had settled at White Bluff on the Tombigbee River, at the present site of Demopolis, founding the Vine and Olive Colony.[12]
