History

19th century

Bay County was created in 1857 from portions of Midland County, Saginaw County, and Arenac County.  Its name references that it "surrounds Saginaw Bay."  Being only sparsely populated at that time, Arenac County government was unorganized and was attached to Saginaw County for administrative purposes. There was considerable opposition to the creation of Bay County from elected officials in both Saginaw and Midland counties. In 1854, a bill introduced to the state legislature to create Bay County was defeated by a small majority.

In 1857, a new bill was introduced into the legislature. After initial opposition from the representatives of Saginaw and Midland counties, a compromise revision that would present the matter for ratification to the voters of "in said county" was passed by the legislature on February 17, 1857. The matter was put before all the voters of Saginaw and Midland counties and was soundly defeated. However, the population within the boundaries proposed for Bay County approved the measure. The bill passed by the legislature included phrasing, which was deliberately included by the Bay City lawyer Chester H. Freeman, that allowed Bay County to claim ratification. Under the act, the county was to become effective April 20, 1857.

Residents of Bay County held elections for county officials in June 1857. However, Saginaw County did not recognize the organization of the new county government. In the winter of 1858, Freeman secured passage of a bill in the legislature that would have confirmed the organization of Bay County. But the bill was vetoed by the governor. However, a case that went before the Michigan Supreme Court in its May 1858 term settled the matter. In the case, a defendant was tried in a Saginaw County court, but filed a plea for abatement, claiming that the supposed offense was committed in Bay County and was not in the jurisdiction of the Saginaw County court. Freeman had represented the defendant and prepared arguments, but became incapacitated due to illness. At the request of Freeman's wife, Colonel William M. Fenton argued the case before the Michigan Supreme Court, with the result that Bay County was declared a fully organized county.

20th century

During World War II, shipyards in Bay County, were used to produce US Destroyers and missile vessels.

In 1978, Bay County became the second Michigan county (after Oakland County) to adopt a County Executive form of government.  Act 139 of 1973 provides for an optional unified form of county government under an appointed County Manager or an elected County Executive. With the County Executive, all departments of the county government that are not headed by a separate elected official (e.g. Treasurer, Clerk, Sheriff, etc.) are under the direction of the County Executive. The County Executive also has veto power over the motions and resolutions passed by the County Commission.

Since the adoption of this form of government, Bay County has had four County Executives: Gary Majeske (R) (1979–1989), Kim Higgs (D) (1989–1993), Thomas Hickner (D) (1993–2016), and James Barcia (D).

Government
From 1932 to 2012, Bay County voted for the Democratic Party candidate in every Presidential election except for five national Republican landslides: 1952, 1956, 1972, 1980 and 1984. However, the county has turned increasingly Republican in recent elections. The November 2022 election resulted in the first majority Republican Board of Commissioners ever sitting in Bay County since the adoption of the Optional Unified Form of County Government (Act 139). Despite this, Bay County had voted Democratic in all 3 statewide races in 2022, and Democrat James Barcia remains as County Executive.

Bay County government is set up under Public Act 139 of 1973. This format provides for an elected County Executive who, as chief administrator, has influence over all departments, except those headed by other elected officials. In that manner, the County Executive appoints and supervises all department heads. It is the duty of the County Executive to coordinate all county activities and unify the management of county affairs, enforce all orders, rules and ordinances passed by the Board of Commissioners and all laws enacted by the state. In addition, the County Executive must submit to the Board of Commissioners a recommended budget each year. The county government operates the jail, maintains rural roads, operates the major local courts,
keeps files of deeds and mortgages, maintains vital records, administers public health regulations, and
participates with the state in the provision of welfare and other social services. The county
Board of Commissioners controls the budget but has only limited authority to make laws or ordinances. Bay County has a Board of Road Commissioners, which consists of three commissioners who are elected and serve six-year staggered terms (one road commissioner elected every two years). The Board is the policy-making body of the Bay County Road Commission and is responsible for establishing budget priorities and managing the annual budget. In Michigan, most local government functions — police and fire, building and zoning, tax assessment, street
maintenance, etc. — are the responsibility of individual cities and townships.
