During the greatest period of the dance evolution in American history (1910-1914), the Tango made its first appearance. It was instantly a hit with the dance-conscious public for its intriguing, asymmetrical, and sophisticated patterns which added a touch of romance to the country’s dance consciousness. The Tango has no clearly defined origin: it may have originated in Argentina, Brazil, Spain, or Mexico, but it clearly descended from an early Spanish folk dance, the Milonga, and bears traces of Moorish and Arabic ancestry. The Tango first came to be known as such, early in the 20th century in Argentina. It was danced, however, under various names throughout all of Latin America.
