Human: I'm trying to find some information about the history of the sombrero. Assistant: 
The sombrero is a traditional Mexican hat, typically made from woven straw and worn by men and women alike. It was originally used as protection from the sun, but has since become an iconic symbol of Mexico and its people. Its origin dates back to pre-Columbian times, when it was first worn by Aztec warriors. During the colonial period, the Spanish introduced the sombrero to Mexico, and it quickly became popular among the indigenous population. In modern times, the sombrero remains a popular fashion accessory, worn for both formal and casual occasions.
