Was soup invented when California was Mexico?

* Soup has been around for a very long time. Soup predates the existence of California as a state or even as part of Mexico. Ancient civilizations in various parts of the world developed their own forms of soup.

* California was part of Mexico from 1821 to 1848. So, while soup existed, new and specific soup recipes may have been created or evolved during that period in California. However, it's not accurate to say that soup was "invented" during that time.

To answer your question more directly:

Soup was not invented when California was Mexico. Soup existed long before that, and it continues to be a popular food today.
