This Mexican and Chicano ballad form developed during the 19th century and reached its peak during the first half of the 20th. Pure folk ballads in their simplicity, their detail, their deadpan performing style, the corridos were the history books, news reports, and editorials of the illiterate. They chronicled the whole of the Mexican Civil war, almost all notable crimes, strikes, and other political events, and a hundred other subjects besides.
A narrative ballad usually sung or spoken to music, the corrido was the most important literary genre of the southwestern border region, where it was popular between the 1830s and the 1930s. Developed by Mexicans and Mexican Americans, the corridos drew upon traditional Spanish ballad forms to articulate singers' experiences of cultural conflict in the borderlands. Characterized by a rapid tempo and brisk narrative pace, these ballads often focus on an "outlaw" hero who defends his rights--as well as those of other Mexicans--against the unjust authority of American officials.
