Tango is a social dance form originating in Buenos Aires, Argentina and Montevideo, Uruguay. The musical styles that evolved together with the dance are also known as "tango".
Early tango was known as tango criollo, or simply tango. Today, there are many tango dance styles, including Argentine Tango, Ballroom tango (American and International styles), Finnish Tango, Chinese Tango, and vintage tangos. The Argentine tango is often regarded as the "authentic" tango since it is closest to that originally danced in Argentina and Uruguay, though other types of tango have developed into mature dances in their own right.
Music and dance elements of tango are popular in activities related to dancing, such as figure skating, synchronized swimming, etc., because of its dramatic feeling and its cultural associations with romance and love.
The dance originated in lower-class districts of Buenos Aires and Montevideo. The music derived from the fusion of music from Europe, the South American Milonga, and African rhythms. Jorge Luis Borge in "El idioma de los argentinos" writes:"Tango belongs to the Rio De La Plata and it is the son of Uruguayan "milonga" and grandson of the "habanera". 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.
In the early years of the twentieth 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 name "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" also called "Argentine Tango". By 1914 more authentic tango stylings were soon developed, along with some variations like Albert Newman's "Minuet" Tango.
In Argentina, the onset in 1929 of the Great Depression, and restrictions introduced after the overthrow of the Hipólito Yrigoyen government in 1930 caused Tango to decline. Its fortunes were reversed as tango again became widely fashionable and a matter of national pride under the government of Juan Perón. Tango declined again in the 1950s with economic depression and as the military dictatorships banned public gatherings, followed by the popularity of Rock and Roll. The dance lived on in smaller venues until its revival in the 1980s following the opening in Paris of the show Tango Argentino and the Broadway musical Forever Tango.
