Parade floats were first introduced in the Middle Ages when churches used pageant wagons as movable scenery for passion plays. Artisan guilds were responsible for building the pageant wagons for their specified craft. The wagons were pulled throughout the town, most notably during Corpus Christi in which up to 48 wagons were used, one for each play in the Corpus Christi cycle. They are so named because the first floats were decorated barges on the River Thames for the Lord Mayor's Show.
Largest
The largest float ever exhibited in a parade was a entry in the 2012 Tournament of Roses Parade that featured Tillman the skateboarding bulldog surfing in an ocean of water. The water tank held over on a float weighing more than. It broke the previous record for the longest single-chassis parade float, which was set in 2010 by the same sponsor. The dogs trained for three months prior to the float's debut at the Tournament of Roses Parade on January 2, 2012. A specially designed “wave” machine was incorporated into the design of the float which created a wave every minute.
Tournament of Roses
Members of Pasadena's Valley Hunt Club first staged the Tournament of Roses Parade in 1890. Many of the members of the Valley Hunt Club were former residents of the American East and Midwest. They wished to showcase their new California homes' mild winter weather. At a club meeting, Professor Charles F. Holder announced, "In New York, people are buried in the snow. Here our flowers are blooming and our oranges are about to bear. Let's hold a festival to tell the world about our paradise." And so the Club organized horse-drawn carriages covered in flowers, followed by foot races, polo matches, and a game of tug-of-war on the town lot. They attracted a crowd of 2000 to the event. Upon seeing the scores of flowers on display, the Professor decided to suggest the name "Tournament of Roses."
The Battle of Flowers parade is in San Antonio, Texas is the only parade in the United States produced entirely by women, all of whom are volunteers. The parade is the oldest event and largest parade of Fiesta San Antonio. The original purpose of the parade was to honor the heroes of the Alamo. In keeping with this tradition, participants are asked to place a flower tribute on the lawn of the Alamo as they pass by.
Dutch flower parades
In the Netherlands, flower parades are a popular tradition. The small country holds some 30 parades, large and small. The world's largest flower parade is held every year in Zundertthe eighth day of the fourth lunar month, a small town in the south of the Netherlands. In Zundert, and most other Dutch parades, floats are built entirely by volunteers, where hamlets compete with each other to build the most beautiful float, judged by an independent jury. Most Dutch flower parades are held in August and September and use mainly dahlia flowers. The dahlia fields are kept by volunteers as well.
The climax of the movie Animal House features the protagonists from the title fraternity surreptitiously launching their own float into a parade featuring legitimate entries from many of their rivals. The float, a giant decorated cake adorned with the words "Eat Me," later splits open to reveal the parade-destroying "Deathmobile" inside. In Ferris Bueller's Day Off the titular character jumps onto a float during a parade and sings several karaoke numbers to the crowd. In the 2011 film Rio the titular character uses the Rio Carnival as a decoy to smuggle his bird friends to the airport so they can escape. Macy's Thanksgiving Day Parade features in several films including Miracle on 34th Street and it's remakes as well as the 2016 version of Ghostbusters.
