History
For thousands of years, indigenous cultures occupied this region, especially along the rivers and creeks. The area was long occupied by the historic Cherokee Nation. In the early 19th century, it was being led by John Ross. The city that is now known as Chattanooga developed at Ross's Landing, a busy trading post recognized as the center of the Cherokee Nation. Over a series of treaties with the United States between 1819 and 1835, the Cherokee had been mostly moved out of the area.
If any Cherokee wished to stay in the area, the head of the family would have to leave the tribe and become an American citizen. Once a citizen, they would be entitled to 640 acres (260 ha) of land. At the time of death, the person's heirs would be entitled to the land. Of the 107 reservations reported to Congress in 1819, only 39 were listed as fee simple. The other 68 reservations were allowed to continue as long as the family stayed on the land. Once the family moved, the land could be sold. This provision made it easier to remove the Cherokee from the area. The 1835 Treaty of New Echota provided the U.S. government a legal basis for the forced removal of the Cherokee, opening their former lands for settlement. Some Cherokee leaders had agreed to this, in the belief that removal was inevitable and they could negotiate decent conditions for their people. The majority of the Cherokee opposed removal.
Hamilton County was formed on October 25, 1819, from portions of Rhea County and Cherokee land that was ceded to the U.S. It was named after Alexander Hamilton, an officer in the American Revolutionary War, member of the Continental Congress, the first U.S. secretary of treasury, and one of the Founding Fathers of the United States.
At the time of the 1820 census, the county counted 821 residents, including 16 blacks, 39 slaves, and about 100 Cherokee living on six reservations. The original legislature ruled that John Gamble, William Lauderdale, and Robert Patterson, the three men who were responsible for founding the county, would conduct all county business in the county seat. The original county seat was in the home of Hasten Poe, who owned a popular tavern located near those three men's farms. In 1822 the County Court was moved to the farm of Ashael Rawlings in Dallas, Tennessee; he was the newly appointed county clerk. After the county seat was moved to Harrison, the Dallas settlement declined. The county seat was finally moved to Chattanooga in 1870.

Natural areas of interest
Raccoon Mountain Caverns is a show cave located 8 miles northwest of downtown Chattanooga. It was originally explored in 1929 by Leo Lambert who developed trails and installed lights and opened the cave to the public on June 28, 1931. The cave was opened under the name Tennessee Caverns. The operators of the cave claim that its explored length is over 5.5 miles (8.9 km).
The Crystal Caverns Cave Spider, Nesticus furtivus, is only known from this one cave. Cave guides will occasionally spot one of these rare spiders and point it out to tourists.
Ruby Falls Cave is a show cave located on the side of Lookout Mountain south of downtown Chattanooga. It was discovered by accident on December 28, 1928, when it was intersected by an elevator shaft that was being drilled to develop Lookout Mountain Cave as a commercial cave. Ruby Falls Cave was intersected at a depth of 260 feet from the surface and Lookout Mountain Cave was reached later at a depth of 420 feet below the surface. The entire project was the work of cave developer Leo Lambert. He named the new cave's waterfall after his wife Ruby. The lower cave, Lookout Mountain Cave, opened to the public on December 30, 1929. Ruby Falls opened to the public on June 16, 1930. Ruby Falls Cave, with its spectacular waterfall proved the more popular of the two caves and it is the only cave open to the public at the present time.
Areas such as Lookout Mountain including the famous Point Park, and Sunset Rock. Point Park is a national military park that is a tribute to the battle of Lookout mountain that took place during the American Civil War.
