Tango is a partner dance, and social dance that originated in the 1880s along the Río de la Plata, the natural border between Argentina and Uruguay. It was born in the impoverished port areas of these countries, in neighborhoods which had predominantly African descendants. The tango is the result of a combination of Rioplatense Candombe celebrations, Spanish-Cuban Habanera, and Argentinean Milonga. The tango was frequently practiced in the brothels and bars of ports, where business owners employed bands to entertain their patrons with music. The tango then spread to the rest of the world. Many variations of this dance currently exist around the world.
On August 31, 2009, UNESCO approved a joint proposal by Argentina and Uruguay to include the tango in the UNESCO Intangible Cultural Heritage Lists
