As the secession crisis developed in early 1861, several Volunteer Companies of the California Militia had disbanded because of divided loyalties and new ones with loyal Union men were sworn in across the state under the supervision of County sheriffs and judges.

compelled the militia to be reorganized. Volunteer companies were to be reorganized, classified, assigned to militia battalions and regiments and staffs were to be provided to them. Administration was improved, bonds required, military duty exacted, enrollments and assessments created, muster rolls defined, activation of the militia determined, disciplinary procedure adopted, courts-martial provided, compensation fixed, arms and equipment provided, and prior conflicting acts repealed. During the Civil War 88 militia companies had been formed to serve, if required, in their respective localities, or to respond to a call from the governor. However, by the end of the Civil War only two of the six Divisions were active and only six of the twelve Brigades of which only the 2nd, 3rd, and 4th Brigades were organized into battalions and regiments.


Later 19th Century

In 1866, the Legislature for the first time employed the term "National Guard" as the title of the organized uniformed troops of the State of California. The statute provided for the organization of the National Guard, General and Special Staffs, formations of companies, service, arms and equipment, created a Board of Organization, formed a Board of Military Auditors, adopted a system of instruction and drill, described in detail the duties of the Adjutant General, created privileges and exemptions, allowances and expenses, limited the issuance of arms to troops only, provided for military musters and active service.
