Métairie is the French term for a small tenant farm which paid the landlord with a share of the produce, also known as sharecropping. In the 1760s, many of the original French farmers were tenants; after the US Civil War, the majority of the community's inhabitants were sharecroppers until urbanization started in the 1910s.
In the 1720s French settlers became the first Europeans to settle Metairie in the area known then as Tchoupitoulas and now as Metairie Ridge, a natural levee formed by an ancient branch of the Mississippi River which flowed through modern-day River Ridge, Metairie, Gentilly, and New Orleans East. It emptied into Mississippi Sound. The Acolapissa Native Americans used this ridge as a road, and it is the oldest road in the New Orleans area. Paved in the 1920s, it is called Metairie Road. An electric streetcar was installed running along Metairie Road in the late 1910s, opening the area to greater development. Upscale housing tracts were constructed off the road in the 1920s; this area is now known as "Old Metairie." It is today the most prestigious area of Metairie. The areas to the north and northwest of Metairie Road were not developed until after World War II. The land between Metairie Ridge and Lake Pontchartrain, which was cypress swamps and marshlands, was drained with the Wood Pump. With development of this new land for residences, Metairie's population grew in the 1940s as a result of cheaper land, lower taxes, and larger lots than in Orleans Parish.
In 1990, Metairie made history when one of its districts elected white supremacist David Duke to the Louisiana state legislature for a single term. In 2005, Hurricane Katrina caused a new migration from Orleans Parish, because housing was needed to replace what had been destroyed in the flooding of the city. It has been a racially neutral migration, with equal numbers of black and white residents moving to Jefferson Parish. The 2010 Census showed that Metairie has increasingly become more diverse.
Veterans Boulevard was laid out alongside a drainage canal, and became a commercial center of the region. The Central Business District of Metairie is located on Causeway Blvd near Lake Pontchartrain. Metairie also has one of the handful of major malls located in the New Orleans metro area. Lakeside Shopping Center is the highest-grossing mall in the New Orleans metropolitan area. In the 1970s and early 1980s, an area of bars and nightclubs opened in a section of Metairie known as "Fat City." Fat City is now the most racially diverse area in the New Orleans Metropolitan Area and is home to a vibrant restaurant scene. Several New Orleans radio and television stations have transmitter facilities in Metairie and Jefferson Parish; two of them, WGNO-TV and WNOL, now have studios and main offices in Metairie. Metairie has a large Mardi Gras season that touts itself as more family-friendly than the New Orleans Mardi Gras.
The 1947 Fort Lauderdale Hurricane with winds of 125 mph (201 km/h) directly hit Metairie. Much of the community was under six feet of water.
