The tango (possibly from Latin tangere, meaning "touch") is a partner dance that originated in the 1890s in the working-class neighborhoods of Buenos Aires (Argentina). Men wanted to be good dancers so the women would choose to dance with them instead of other men. This led the men of all nationalities to practice dancing together so they could be as good as possible. The merging styles of the immigrants and the Argentina style created what we now know as the Tango.
