Moon Edwin Landrieu was an American lawyer and politician who served as the 56th mayor of New Orleans from 1970 to 1978. A member of the Democratic Party, he represented New Orleans' Twelfth Ward in the Louisiana House of Representatives from 1960 to 1966, served on the New Orleans City Council as a member at-large from 1966 to 1970, and was the United States Secretary of Housing and Urban Development under U.S. president Jimmy Carter from 1979 to 1981.

The New Orleans City Council is the legislative branch of the City of New Orleans, Louisiana, United States. The current mayor-council form of city government was created in 1954, following the 1950 amendment of the state constitution that provided for a home rule charter for the city. The 1954 Charter provided for seven members, five elected from single-member districts, and two elected at-large, replacing the 1912 Charter, which provided for a commission form of government with a mayor and four commissioners.
