History
Founding
Sonoma State University was established by the California State Legislature in 1960 to be part of the California State College system, with significant involvement of the faculty from San Francisco State University. As with all California State Colleges, Sonoma State later became part of the California State University system. Sonoma opened for the first time in 1961, with an initial enrollment of 274 students. Classes offered took place in leased buildings in Rohnert Park, where the college offered its first four-year Bachelor of Arts degree in Elementary Education. The small first graduating class received their degrees in the parking lot of the temporary campus.

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
