Lyon County, Iowa

Lyon County, Iowa
Lyon County is the most northwesterly county of the U.S. state of Iowa. As of the 2020 census, the population was 11,934. The county seat is Rock Rapids.
Lyon County is named in honor of Brigadier General Nathaniel Lyon, who served in the Mexican–American War and the Civil War. He was killed at the Battle of Wilson's Creek, Missouri, on August 10, 1861, after which the county was named for him. The county's name was originally Buncombe County, but was changed by the state legislature on September 11, 1862.
History
The land that makes up Lyon County was ceded to the federal government by the Sioux Native Tribe through a treaty signed on July 23, 1851. The boundaries of the county were set on January 15, 1851, and attached to Woodbury County (then called Wahkaw County) for administration purposes. Lyon County was split from Woodbury County on January 1, 1872.
The first non-indigenous resident to live in Lyon County was Daniel McLaren, known as "Uncle Dan". He lived near the Sioux River for a short time, spending his time hunting and trapping. He moved out of the county early in its settlement to stake a claim further west. The second settler in the area was known as "Old Tom", a hunter and trapper who lived briefly near present-day Rock Rapids. While setting his traps, Old Tom was killed by Sioux tribespeople.
In 1862–1863, a group of men from the east coast spent time in the county on a hunting trip. They were: Roy McGregor, George Clark and Thomas Lockhart. During the winter, Lockhart and McGregor were hunting elk along the Little Rock creek and encountered a group of Sioux tribespeople. Lockhart was killed by an arrow, but McGregor was able to escape and rejoin Clark. The two continued to hunt and trap until March 1863. During a spring flood, Clark was drowned and McGregor decided to move back east.
The first permanent settlement in Lyon County was built by Lewis P. Hyde in July 1866. The county's population reached 100 persons in 1869, entirely through migration and settlement. The first non-indigenous child born in the county was Odena Lee, born on May 28, 1871. The first election in the county was held on October 10, 1871, and recorded 97 votes.

Politics
Lyon County is among the most GOP-friendly counties in Iowa. Only two Democrats have ever won the county: Grover Cleveland by a twenty-vote plurality in 1892, and Franklin D. Roosevelt in 1932 and 1936. Though Roosevelt carried the county by a very comfortable margin in both elections, the county went back to its solid Republican roots in 1940 and has not been won by a Democrat since, with Michael Dukakis being the last Democrat to even reach 30%. The only other times someone besides a Republican won this county were in 1912 when Theodore Roosevelt carried it in the split election, and in 1924 when Robert M. La Follette carried it by a narrow plurality. Even so, both of these candidates were affiliated with the Republican Party outside of these elections.
