The surrounding area, which is now the larger Buckhead community, remained dominated by country estates until after World War I, when many of Atlanta's wealthy began building mansions among the area's rolling hills. The area that is now the Buckhead district was annexed by Atlanta in 1952, following an earlier attempt by Mayor William B. Hartsfield in 1946 that was voted down by residents. In 1956, an estate known as Joyeuse was chosen as the site for a major shopping center to be known as Lenox Square, starting the development of Peachtree Road as a major commercial, financial, and high-rise residential corridor.
