The most prolific and diverse mask making in Mexico takes place in the state of Guerrero. For the most part this is carried out by the Nahuatl people but Tlapanec, Amuzgo, and Mixtec people also perform with masks in Guerrero. Some of the most popular dance dramas are Moor and Christian battles, Conquista dance, Tres Potencias (3 powers), and Siete Vicios (7 vices) dance. By far the most impressive masks in Guerrero are used in Zitlala and Acatlan during La Fiesta de la Santa Cruz (Holy Cross) in early May. Guerrero is an arid state and for centuries this fiesta takes place in order to promote a good agricultural and rainy season. Heavy expressive stitched leather tigre (jaguar) helmets protect wearers in aggressive combats to honor San Nicolas, primitive tlacololero masks get worn with giant hats as they crack their whips to mimic desired thunder, and elegant goat masks are used in la danza de los chivos. The southern coast of Guerrero is home to descendants of African slaves who make powerful devil masks for All Saints and All Souls celebrations.
