The Governor of California is the head of government of the U.S. state of California. The California Governor is the chief executive of the state government and the commander-in-chief of the California National Guard and the California State Military Reserve.
Established in the Constitution of California, the governor's responsibilities also include making the annual State of the State address to the California State Legislature, submitting the budget, and ensuring that state laws are enforced. The position was created in 1849, the year before California became a state.
As of this writing, Edmund G. "Jerry" Brown Jr. is the longest-serving governor, surpassing Earl Warren's 10-year tenure in 2013.
Governors of California in the works of Harry Turtledove
Other alternate history works may make reference to California Governors who either died before the point of divergence or did nothing important after it. Stories set in OTL may make reference to past, present, and/or future Governors who are not specifically fictionalized within the context of the work.
Historical Governors in non-Gubernatorial roles
George Stoneman is referenced in The Guns of the South and "Must and Shall" in his OTL role as a General. Guns ends well before the date of his historical governorship, while the posthumous reference in "Must" makes no reference to his politics.
Earl Warren appears in the Colonization trilogy as the President of the United States. It is acknowledged that he was California's State Attorney General at the POD, but it is not revealed whether he was ever Governor.
