what is the most popular dance in argentina? where did the dance begin?

The most popular dance in Argentina is the tango. It originated in the late 19th century in the working-class neighborhoods and impoverished port areas along the Río de la Plata, between Buenos Aires, Argentina, and Montevideo, Uruguay. Tango developed as a social dance combining influences from Argentine Milonga, Spanish-Cuban Habanera, and Afro-Argentine dance forms. It was initially practiced in streets, bars, and brothels of the port areas and later spread globally. The dance is deeply tied to Argentina's cultural identity and history.
