Tango is a dance that has influences from European and African culture.^[5] Dances from thecandombe 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.^[6] 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.^[7]

In the early years of the 20th century, dancers and orchestras from Buenos Aires travelled toEurope, 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 theone-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.

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.

In 2009 the tango was declared as part of the world's "intangible cultural heritage" byUNESCO.^[8]
