History
Like many towns in Southern Louisiana, Sunset began as a railroad town (for the out-distribution of cotton and sweet potatoes and the in-distribution of specialty goods), was incorporated in 1904, and had its first village meeting that December 7. Victor Hugo Sibille was the first mayor. As part of a large-scale conversion of arable land away from cotton (due to the mass-destruction from the cotton boll weevil) and toward sweet potatoes in the late 19th century,[7] the city gave itself the nickname "Sweet Potato Capital of the Nation" at the turn of the 20th century.[8] According to local lore, The Bank of Sunset was one of the very few that did not close throughout the Great Depression of 1929.[9]
