The danzón arrived with traders and refugees of the Ten Years' War through the ports in Veracruz and Yucatan. While the genre has gone out of style in Cuba, it continues to be popular in Mexico. It reached its peak in popularity in the ballrooms of Mexico City in the 1940s, then went through a decline and afterwards entered a renaissance in the late 20th century. The most famous Mexican danzón piece is "Danzón No. 2".
