Chinelos are a kind of traditional costumed dancer which is popular in the Mexican state of Morelos, parts of the State of Mexico and the Federal District of Mexico City, especially the boroughs of Milpa Alta and Xochimilco. The tradition arose from the blending of indigenous and Catholic traditions, most notably Carnival, with its permission to be masked and to mock. Chinelos mock Europeans and European mannerisms from the colonial period up to the end of the 19th century. The Chinelos tradition is strongest in Morelos, especially around Carnival, but Chinelos now appear at other festivities such as Independence Day celebrations, private parties and more.
