I'm trying to find out about the history of the sombrero.

The sombrero is a traditional Mexican hat that is worn by men and women alike. It was originally made from woven palm leaves, but today it is usually made of felt or straw. The sombrero has been around since pre-Columbian times, and was used as protection against the sun, wind, and rain. In modern times, the sombrero has become a popular symbol of Mexican culture and identity.
