This entire territory was called Cherokee County; the following year the Assembly organized the territory as the nine counties that still exist in the 21st century. Rome was founded in 1834 as European Americans increasingly settled in Georgia. Founders were Col. Daniel R. Mitchell, Col. Zacharia Hargrove, Maj. Philip Hemphill, Col. William Smith, and John Lumpkin (nephew of Governor Lumpkin); most were veterans of the War of 1812. They held a drawing at Alhambra to determine the name of the new city, with Col. Mitchell submitting the name of Rome because of the area's hills and rivers. Mitchell's submission was drawn, and the Georgia Legislature chartered Rome as an official city in 1835. The county seat was subsequently moved east from the village of Livingston to Rome. With the entire area still occupied primarily by Cherokee, the city developed to serve the agrarian needs of the new cotton-based economy. Invention of the cotton gin in the late eighteenth century made processing of short-staple cotton profitable. This was the type of cotton that best thrived in the upland areas, in contrast to that grown on the Sea Islands and in the Low Country. Much of upland Georgia was developed as what became known as the Black Belt, named for the fertile soil. Planters brought or purchased many enslaved African Americans as workers for the labor-intensive crop. The leading Cherokee participated in the cultivation of cotton as a commodity crop, which soon replaced deer-skin trading as a source of wealth in the region. The first steamboat navigated the Coosa River to Rome in 1836, reducing the time-to-market for the cotton trade and speeding travel between Rome and New Orleans on the Gulf Coast, the major port for export of cotton. By 1838, the Cherokee had run out of legal options in resisting removal. They were the last of the major Southeast tribes to be forcibly moved to the Indian Territories (in modern-day Oklahoma) on the Trail of Tears. After the removal of the Cherokee, their homes and businesses were taken over by whites, with much of the property distributed through a land lottery. The Rome economy continued to grow. In 1849, an rail spur to the Western and Atlantic Railroad in Kingston was completed, significantly improving transportation to the east. This route was later followed in the 20th-century construction of Georgia Highway 293. By 1860 the population had reached 4,010 in the city, and 15,195 in the county.
