Atlanta was founded in 1837 as the end of the Western & Atlantic railroad line (it was first named Marthasville in honor of the then-governor’s daughter, nicknamed Terminus for its rail location, and then changed soon after to Atlanta, the feminine of Atlantic — as in the railroad). Today the fast-growing city remains a transportation hub, not just for the country but also for the world: Hartsfield-Jackson Atlanta International Airport is the world’s busiest in daily passenger flights. Direct flights to Europe, South America, and Asia have made metro Atlanta easily accessible to the more than 1,000 international businesses that operate here and the more than 50 countries that have representation in the city through consulates, trade offices, and chambers of commerce.
