Tango dance and tango music originated in the area of the Rio de la Plata, and spread to the rest of the world soon after. Early tango was known as tango criollo, or simply tango. Today, there are many tango dance styles, including Argentine tango, Uruguayan tango, Ballroom tango (American and International styles), Finnish tango, and vintage tangos. What many[according to whom?] consider to be the authentic tango is that closest to that originally danced in Argentina and Uruguay, though other types of tango[which?] have developed into mature dances in their own right. In 2009, Argentina and Uruguay suggested that the Tango be inscribed onto the UNESCO Intangible Cultural Heritage Lists and in October of the same year UNESCO approved it

Tango is a dance that has influences from European and African culture. Dances from the candombe ceremonies of former slave peoples helped shape the modern day Tango. The dance originated in lower-class districts of Buenos Aires and Montevideo. The music derived from the fusion of various forms of music from Europe.[5] The word "tango" seems to have first been used in connection with the dance in the 1890s. Initially it was just one of the many dances, but it soon became popular throughout society, as theatres and street barrel organs spread it from the suburbs to the working-class slums, which were packed with hundreds of thousands of European immigrants, primarily Italians, Spanish and French.[6] In the early years of the 20th century, dancers and orchestras from Buenos Aires travelled to Europe, and the first European tango craze took place in Paris, soon followed by London, Berlin, and other capitals. Towards the end of 1913 it hit New York in the USA, and Finland. In the USA around 1911 the word "tango" was often applied to dances in a 2/4 or 4/4 rhythm such as the one-step. The term was fashionable and did not indicate that tango steps would be used in the dance, although they might be. Tango music was sometimes played, but at a rather fast tempo. Instructors of the period would sometimes refer to this as a "North American tango", versus the "Rio de la Plata tango". By 1914 more authentic tango stylings were soon developed[which?], along with some variations like Albert Newman's "Minuet" tango.

The Tango consists of a variety of styles that developed in different regions and eras of Argentina as well as in other locations around the world. The dance developed in response to many cultural elements, such as the crowding of the venue and even the fashions in clothing. The styles are mostly danced in either open embrace, where lead and follow have space between their bodies, or close embrace, where the lead and follow connect either chest-to-chest (Argentine tango) or in the upper thigh, hip area (American and International tango).
