Anti-Mexican sentiment is an attitude towards people of Mexican descent, Mexican culture and/or accents of Mexican Spanish, most commonly found in the United States.
Its origins in the United States date back to the Mexican and American independence wars, and the struggle over the disputed Southwestern territories that once belonged to Spain through the establishment of Catholic missions. This eventually would lead to the war between the two nations and the defeat of Mexico, which came with a great loss of territory. In the 20th century, anti-Mexican sentiment continued to grow after the Zimmermann Telegram incident between the Mexican government during the Mexican Revolution and the German Empire during World War I.
Throughout U.S. history, most Americans have circulated many negative stereotypes regarding Mexican Americans. Such stereotypes have long circulated in film and other media.
