## History

Sacramento County was one of the original counties of California, which were created in 1850 at the time of statehood. The county was named after the Sacramento River, which forms its western border.

## Government and policing
### Government

The Government of Sacramento County is defined and authorized under the California Constitution, California law, and the Charter of the County of Sacramento. Much of the Government of California is in practice the responsibility of county governments such as the Government of Sacramento County, while municipalities such as the city of Sacramento and Folsom provide additional, often non-essential services.
It is composed of the elected five-member Board of Supervisors, several other elected offices including the Sheriff, District Attorney, and Assessor, and numerous county departments and entities under the supervision of the County Executive Officer. In addition, several entities of the government of California have jurisdiction conterminous with Sacramento County, such as the Sacramento County Superior Court.
Under its foundational Charter, the five-member elected Sacramento County Board of Supervisors (BOS) is the county legislature. The board operates in a legislative, executive, and quasi-judicial capacity. The current members are:
* Phil Serna, District 1
* Patrick Kennedy, District 2
* Rich Desmond, District 3
* Sue Frost, District 4
* Pat Hume, District 5
The Sacramento County Code is the codified law of Sacramento County in the form of local ordinances passed by the Board of Supervisors.

### Policing

The Sacramento County Sheriff provides court protection and jail management for the entire county. It provides patrol and detective services for the unincorporated areas of the county. Incorporated municipalities within the county that have their own municipal police departments or contract with the Sacramento County sheriff for their policing are: Elk Grove, 170,000, municipal department; Citrus Heights, 88,000, municipal department; Folsom, 78,000, municipal department; Isleton, sheriff contract; Rancho Cordova, 73,000, sheriff contract; Galt, population 26,000, municipal department.
Other law enforcement agencies in the county include the Sacramento County Park Rangers that service the County Parks, Twin Rivers Unified School District Police servicing police services for Twin Rivers School District, and the Fulton-El Camino Park District Police Department servicing Recreation and Park Districts.
The Fulton- El Camino Park District Police operating under the Fulton - El Camino Recreation and Park District was disbanded as of 11/26/2024 following an alleged mismanagement of Government Funds, ethical and moral dilemmas by Emily Ballus (General Manager) and Beth Johnson (Interim Chief of Police). ABC10 conducted a investigation regarding misappropriation of funds.

### Overview

Sacramento County was politically competitive in most presidential elections between 1976 and 2004, but now votes significantly in favor of the Democratic candidates. Candidates from the Democratic Party have carried the county in the past eight presidential elections, and have won a majority of the county's votes four times during that time (in 2008, 2012, 2016, and 2020). The city of Sacramento is strongly Democratic, while rural areas are strongly Republican; suburban areas are more divided. This pattern is also present in congressional and state legislative elections. The last Republican presidential candidate to win a majority in the county was George H. W. Bush in 1988.
