Located in Orleans Parish, New Orleans was founded in 1718. It became the capital of French Louisiana in 1722 and continued as the capital when Louisiana achieved statehood on April 30, 1812. It became part of Orleans County (now extinct) on the same day. In 1849 it was replaced by Baton Rouge as the state capital, although it temporarily served as the capital again from 1865 until 1880.
