History

Washington County was created on December 7, 1836, by the Wisconsin Territory Legislature, with Port Washington designated as the county seat. It was run administratively from Milwaukee County until 1840, when an Act of Organization allowed the county self-governance, and the county seat was moved to Grafton, then called Hamburg. This solution was not satisfactory, as at that time four cities were vying to become the county seat: Port Washington, Grafton, Cedarburg, and West Bend. At least four inconclusive elections were held between 1848 and 1852, but the results were unusable due to accusations of foul play and serious irregularities.

In 1852, the state Legislature attempted to split the county into a northern and southern half, with the northern half retaining the name and the southern half becoming Tuskola County. Voters refused this decision, so in 1853 the Legislature again split the county, this time into a western and eastern portion. The western portion remained Washington County, with West Bend as its county seat, while the eastern portion became Ozaukee County, with Port Washington as its county seat.
