Our modern ballroom jive has a colourful history growing out of African American dance clubs of the 1930’s. It has taken on many names including the Lindyhop, the Jitterbug, the Boogie Woogie and, in 1968, the Jive was accepted as the fifth Latin dance in ballroom competitions. The modern form of ballroom jive in the 1990s–present, is a very happy and boppy dance, the lifting of knees and the bending or rocking of the hips often occurs. The jive starts with a rock step followed by two triple steps.
