Question: When was the kind of dance that The Jitterbug Stroll was choreographed developed?
Context: The Jitterbug Stroll is a swing line dance choreographed in 1992 by Ryan Francois, a Lindy Hop dancer and teacher.  Ryan Francois is the creator of The Jitterbug Stroll It is usually danced to swing music with 12 bar blues structure such as Woody Herman's "Woodchopper's Ball" or Steven Mitchell's "The Jitterbug Stroll", a modern song created for this choreography. Cajun Jitterbug is a style of Cajun dancing with two variations.  The main style is a classic two-step form of a six-count East Coast Swing, which is differentiated from the one-step Cajun Jig.  The other is considered a cowboy-style of Jitterbug or swing dance, also referred to as the Lake Charles Slide, the Cowboy Jitterbug and the Whiskey River Jitterbug. The Charleston Stroll is a swing line dance choreographed by Sing Lim from Singapore to the song Put A Lid On It by the Squirrel Nut Zippers.  It can be found danced in many swing scenes all over the world. "Swing dance" is a group of dances that developed with the swing style of jazz music in the 1920s-1940s, with the origins of each dance predating the popular "swing era".  During the swing era, there were hundreds of styles of swing dancing, but those that have survived beyond that era include: Lindy Hop, Balboa, Collegiate Shag, and Charleston.  Today, the most well-known of these dances is the Lindy Hop, which originated in Harlem in the early 1930s.  While the majority of swing dances began in African American communities as vernacular African American dances, some swing era dances, like Balboa, developed outside of these communities. The jitterbug is a kind of dance popularized in the United States in the early twentieth century and is associated with various types of swing dances such as the Lindy Hop, jive, and East Coast Swing. "The Jitterbug" was a song sung by Dorothy, together with the Scarecrow, Tin Man and Cowardly Lion, that was cut from the soundtrack of the 1939 film "The Wizard of Oz".  It was both a jazzy development of the plot and a nod to the then-popular bobby-soxer dance craze.  As the song begins, the four friends see a jitterbug flitting in the shadows from tree to tree and become frightened.  The refrain that they sing is: "Oh, the bats and the bees and the breeze in the trees have a terrible, horrible buzz.  ... So, be careful of that rascal/Keep away from The Jitterbug."  The Jitterbug puts a magical influence on the characters, forcing them to dance the Jitterbug frenetically.  Soon there are many jitterbugs, and eventually, everyone collapses from exhaustion and are subdued by the Witch's army of flying monkeys. Harold Jerome "Chuck" Willis (January 31, 1926 or 1928 – April 10, 1958) was an American blues, rhythm and blues, and rock and roll singer and songwriter.  His biggest hits, "C. C. Rider" (1957) and "What Am I Living For" (1958), both reached No.1 on the "Billboard" R&B chart.  He was known as The King of the Stroll for his performance of the 1950s dance the stroll. Hand dancing, also known as "D.C. hand dancing" or "D.C. swing", is a form of swing dance that can be traced as far back as the 1920s, from Lindy Hop, to Jitterbug and to the 50s when Washington, D.C. developed its own version and named it Hand Dance.  It is characterized by gliding footwork and continuous hand connection/communication between the partners, hence its name.  It fell out of favor during the disco era, but in the 80s, Hand Dance resurfaced in the Washington dance community. In latin dancing, the jive is a dance style that originated in the United States from African-Americans in the early 1930s.  It was popularized in 1934 by Cab Calloway.  It is a lively and uninhibited variation of the Jitterbug, a form of Swing dance.  Glenn Miller introduced his own jive dance in 1938 with the song "Doin' the Jive" which never caught on.
