The Veiled Prophet Ball (commonly referred to as the VP Ball) is a dance held each December in St. Louis, Missouri, USA, by a secret society named the "Veiled Prophet Organization" (often referred to as "the VP"), first founded by prominent St. Louisans in 1878. The founders' intent was to create an annual local celebration similar to Mardi Gras in New Orleans, eventually to include pageantry and costuming as well as a parade with floats. Each year, one member of the Veiled Prophet Organization is chosen to serve as the "Veiled Prophet of Khorassan," to preside over the VP Ball. Five of the debutantes who attend the ball (all attend by invitation only) are chosen by secret process to make up the "Veiled Prophet's Court of Honor." One is chosen to be crowned the "Queen of Love and Beauty" by the Veiled Prophet.
Events also included the Veiled Prophet Fair (or "VP Fair"). In the face of increasing criticism of using civic resources to support a socially exclusive organization, this was renamed as Fair St. Louis in 1992 and broadened in appeal. The Fair was moved from the riverfront to Forest Park in 2014 and 2015 due to construction in the area around the Gateway Memorial Arch and reworking of roadways and the park.
The event had its roots in the St. Louis Agricultural and Mechanical Fair, an annual harvest festival which had been held in St. Louis since 1856. It attracted agricultural crops, crafts, demonstrations and attendees from throughout the region. In the economic difficulties after the American Civil War in the 1870s, such events declined. City boosters devised the Veiled Prophet Fair in an attempt to reclaim from the rapidly growing city of Chicago, pre-eminence for St. Louis as a manufacturing center and agricultural shipping point.
On March 20, 1878, Charles Slayback, a grain broker and former Confederate cavalryman (who had spent several years in New Orleans after the Civil War and become acquainted with its Mardi Gras traditions) called a meeting of local business leaders at the Lindell Hotel. Together with his brother Alonzo, Slayback created a mythology for a secret elite society, whose public demonstrations would coincide with the annual fair. From Irish poet Thomas Moore, the Slaybacks borrowed the name of the Veiled Prophet of Khorassan; they also incorporated features from the Mystick Krewe of Comus of New Orleans. In their version, the Prophet was a world traveler who had made St. Louis his home base. The first parade, attracting over 50,000 spectators, and grand ball were staged that year on October 8, 1878.
