Context_5 : The history of Atlanta dates back to 1836, when Georgia decided to build a railroad to the U.S. Midwest and a location was chosen to be the line's terminus. The stake marking the founding of "Terminus" was driven into the ground in 1837 (called the Zero Mile Post). In 1839, homes and a store were built there and the settlement grew. Between 1845 and 1854, rail lines arrived from four different directions, and the rapidly growing town quickly became the rail hub for the entire Southern United States. During the American Civil War, Atlanta, as a distribution hub, became the target of a major Union campaign, and in 1864 Union William Sherman's troops set on fire and destroyed the city's assets and buildings, save churches and hospitals. After the war the population grew rapidly, as did manufacturing, while the city retained its role as a rail hub. Coca-Cola was launched here in 1886 and grew into an Atlanta-based world empire. Electric streetcars arrived in 1889, and the city added new "streetcar suburbs".
