History With the establishment of the Minnesota Territory in 1849, nine counties, including Ramsey County, were created. In 1849, Ramsey County included all of what later became the present-day counties of Ramsey, Anoka, Isanti, and Kanabec, as well as parts of Washington, Pine, Carlton, Aitkin, Mille Lacs, and Hennepin. One of Ramsey County's early settlers was Heman Gibbs, whose farm is now the Gibbs Museum of Pioneer and Dakotah Life (Gibbs Farm) in Falcon Heights. Ramsey County remained largely farmland until small villages began to appear in the late 19th century, with the incorporation of North St. Paul in 1887, New Brighton in 1891, and White Bear Lake in 1921.

Government and politics Ramsey County is overwhelmingly Democratic in presidential elections, not having voted for a Republican presidential nominee since 1924. In 2020, Democratic nominee Joe Biden received the largest share of the vote for any candidate in the county's history, with over 71%.
