In the 19th century the square was the Place d'Armes, the traditional site of important ceremonies and parades.
On December 18, 1814, Andrew Jackson reviewed about 6,000 troops there. His speech, translated by Edward Livingston, urged unity against a common enemy. The Americans then won the Battle of New Orleans.
The square kept the Place d'Armes name until 1851, when the current Andrew Jackson statue was erected and it became Jackson Square. It is a National Historic Landmark.
