Ballroom dancing was once thought to be a kind of exclusivity reserved only for the wealthy and privileged. Ballroom dancing was a secular event in the 17th and 19th centuries, and only members of the nobility classes could participate. Ballroom dancing became regarded as a relic of the past in the twentieth century. However, over the course of the twentieth century, they gradually began to open training courses for trainers. So, a decade later, ballroom dancing has regained popularity and is now available to the general public.
