History

Early towns in Washington County grew along the St. Croix River. This river now forms the border with Wisconsin. The river was important for moving settlers and floating logs downstream. The area had many forests, so logging and lumber were big businesses early on.

The first settlers arrived near Afton in 1837. In 1838, people started a settlement called Dacotah near what is now Stillwater. A sawmill was built in Marine-on-St.-Croix in 1839. Another sawmill opened in Stillwater in 1844. These sawmills were very successful, and people moved from Dacotah to Stillwater.

This area was part of Wisconsin Territory until Wisconsin became a state in 1848. Leaders like Joseph Renshaw Brown held a meeting in Stillwater on August 26, 1848. They asked the U.S. Congress to create a new territory called "Minnesota." Because of this meeting, Stillwater is known as the "Birthplace of Minnesota." Congress agreed and created Minnesota Territory on March 3, 1849.

The new territory's government created nine counties in October 1849. Washington County was one of them. It was named after George Washington. Stillwater was chosen as the county seat. The county's first sheriff started work in 1849, and its first school district began in 1850.

After most of the forests were cut down, Washington County's economy changed. It became mostly about farming. As nearby Ramsey County and St. Paul grew, parts of Washington County became popular for tourism. Places like Mahtomedi and Landfall developed this way. Later, in the 1900s, many people moved to the county as St. Paul's suburbs expanded.
