The city and the parish of Orleans operate as a merged city-parish government. The original city was composed of what are now the 1st through 9th wards. The city of Lafayette (including the Garden District) was added in 1852 as the 10th and 11th wards. In 1870, Jefferson City, including Faubourg Bouligny and much of the Audubon and University areas, was annexed as the 12th, 13th, and 14th wards. Algiers, on the west bank of the Mississippi, was also annexed in 1870, becoming the 15th ward.
