The city had its inception in 1820 when. President Monroe directed the Surveyor General "to reserve the site for a town to be called Decatur." The project was turned over to the Decatur Land Co. in 1820, but was still a part of the Cherokee Reservation until 1826, when the Alabama Legislature issued a charter, December 8, to the town of Decatur. The first settlement was made by Dr. Henry Rhodes at the eastern end of Muscle Shoals, "at the western terminus of Tennessee river navigation to Chattanooga." At the old Indian crossing of the river, Dr. Rhodes established a ferry. This circumstance accounts for the first name of the town being Rhodes Ferry. In 1829 he built a rope and bagging factory, supplying it with raw material from a field of hemp, planted on the north side of the river. He was later joined by Gen. Jesse Winston Garth, Simon Sykes, and Dr. Dancy, all men of considerable wealth, who had been the promoters of the land company formed in 1820. The first conveyance was issued by the company in July, 1821, and transferred to Amos Hardin for $51, the lot now located on the corner of Water and Canal Streets, fronting the river.
The first banking institution was a branch of the State bank, established in a log cabin in 1832. Its first money was $2,000 in silver, brought from New Orleans to Florence by steamboat and thence to Decatur by wagon.
The first railroad, properly so-called, in the State, was built in 1832 to connect Tuscumbia and Decatur and to avoid the Muscle Shoals. Upon its completion in 1834, thousands of people came, some of them many days' journey, to see the wonder. A Masonic Hall was built in 1834, the lower floor being used for school and church purposes. The first church was built by the Methodists in 1835. In 1836 the first brick store-building, known as the Hines Building, and a brick warehouse at the river, were erected. In 1838 a large cotton factory was built and in 1839 the Baptists erected a brick church.
