Tango dates back to the late 19th century in the slums of Buenos Aires.  Lonely immigrants from Europe and Africa and social outcasts needed an escape from their feelings.  They went around seeking ways to drown out their sorrows by drinking, finding temporary friendship and entertainment to ease their depression, landing them in brothels.  They expressed their feelings through music and developed a music and dance that showed their emotions of pain, sorrow, and fatality.
The dance was developed to show the relationship between a pimp and his prostitute which was filled with emotions and sexual energy. Tango was further refined in the early 1900′s in a less vulgar form.  It was then exported to France where it gained popularity with Parisian high society. This added the classy clothes, lyrics, orchestra and the ballroom style.  Tango became popular all over the United States of America and Europe and was embraced by Argentina’s upper class who once shunned the dance in the beginning.
