In the United States, a prom, short for promenade, is a formal dance held at the end of the years of high school and college, called junior prom and senior prom respectively. In British English such an event would be called a ball, although in Canada, Australia, and New Zealand it is also often called a formal. In Australian schools the terms used are either formal or sometimes as Leaver's Dinner, usually so when the night includes a meal. In Ireland it is known as a debs (an abbreviation of debutante ball). In the U.S. a "formal" is typically a similar dance that is held by a fraternity or sorority affiliated with a certain college or university. In Australia, the term "prom" has also come into sparse usage and in Britain it is becoming widespread, because of US influence. The name is derived from the late ninteenth century practice of a Promenade ball. The end of year tradition stemmed from the Graduation Ball tradition.

Kansas is a Midwestern state in the United States. The state is named after the Kansas River that flows through it, which in turn derived its name from the Siouan word Kansa meaning "People of the south wind."

Located in the heartland of the country, Kansas is home to the geographical center of the contiguous United States. Historically home to large numbers of Native Americans who hunted buffalo there, the state was first settled by white Americans in the 1850s. Beginning in 1854, abolitionists from New England and pro-slavery settlers from neighboring Missouri rushed to the territory to determine if Kansas would become a free state. Known as Bleeding Kansas, the state was a hotbed of violence and chaos in its early days as these forces collided. In 1861 Kansas entered the Union as a free state. After the Civil War, the population of Kansas exploded as wave after wave of immigrants turned the desolate prairie into productive farmland. Today Kansas is one of the most productive agricultural states, leading the nation in wheat production.
