The gentrification of some its neighborhoods, initially spurred by the 1996 Summer Olympics, has intensified in the 21st century with the growth of the Atlanta Beltline. This has altered its demographics, politics, aesthetics, and culture. History Native American settlements For thousands of years prior to the arrival of European settlers in North Georgia, the indigenous Creek people and their ancestors inhabited the area. Standing Peachtree, a Creek village where Peachtree Creek flows into the Chattahoochee River, was the closest Native American settlement to what is now Atlanta. Through the early 19th century, European Americans systematically encroached on the Creek of northern Georgia, forcing them out of the area from 1802 to 1825. The Creek were forced to leave the area in 1821, under Indian Removal by the federal government, and European American settlers arrived the following year. Western and Atlantic Railroad In 1836, the Georgia General Assembly voted to build the Western and Atlantic Railroad in order to provide a link between the port of Savannah and the Midwest. The initial route was to run southward from Chattanooga to a terminus east of the Chattahoochee River, which would be linked to Savannah. After engineers surveyed various possible locations for the terminus, the "zero milepost" was driven into the ground in what is now Foundry Street, Five Points. When asked in 1837 about the future of the little village, Stephen Harriman Long, the railroad's chief engineer said the place would be good "for one tavern, a blacksmith shop, a grocery store, and nothing else". A year later, the area around the milepost had developed into a settlement, first known as Terminus, and later Thrasherville, after a local merchant who built homes and a general store in the area. By 1842, the town had six buildings and 30 residents and was renamed Marthasville to honor Governor Wilson Lumpkin's daughter Martha. Later, John Edgar Thomson, Chief Engineer of the Georgia Railroad, suggested the town be renamed Atlanta. The residents approved, and the town was incorporated as Atlanta on December 29, 1847. Civil War By 1860, Atlanta's population had grown to 9,554. During the American Civil War, the nexus of multiple railroads in Atlanta made the city a strategic hub for the distribution of military supplies. In 1864, the Union Army moved southward
