History
A fire on December 11, 1991, heavily damaged the Page County Courthouse. The fire was believed to have started in the attic and spread throughout much of the building. Multiple area fire departments fought the blaze and saved the structure. Court services were relocated to several buildings in Clarinda and other areas of Page County as repairs were made to the courthouse. After $2 1/2$ years of work, the courthouse was re-occupied in March 1994.

Politics
Just like Cass County, Iowa, Page County has long been a Republican stronghold going back generations. Franklin D. Roosevelt in his 1932 landslide was the only Democrat to win the county post-Civil War, and even he couldn't hold onto the county 4 years later despite winning in an even bigger landslide.

O'Brien County, Iowa

O'Brien County is a county in the U.S. state of Iowa. As of the 2020 United States Census, the population was 14,182. The county seat is Primghar.

History
By the time Iowa attained statehood (December 28, 1848), its Territorial Legislature had created 44 counties. On January 15, 1851, the new State Legislature created another 49 counties, defining them by lines of survey. O'Brien was among the 49 units thus created. It consists of four survey townships, each formed by 36 square miles arranged in a 6x6 layout, for a nominal 576 square miles total area. The county was named for William Smith O'Brien, a leader for Irish independence in 1848.

The new county's first settler arrived in 1856; Hannibal H. Waterman brought his wife and a daughter to the southeast portion (present Waterman Township). His homestead formed the nucleus of the county's first community, and a small building was erected there to function as a courthouse.

By 1872 the county comprised several small communities, and residents of those groups felt the county's business should be conducted in a more central location. An election was held, the outcome of which was to create a new county seat at its midpoint. A 40 acre tract at the center of the county was surveyed and platted; its name (Primghar) was created from the initials of eight persons involved with the platting. The previous courthouse building was transported to this new location.

In 1874 a 35-foot square building was erected on the present location at a cost of $2,000, to replace the first structure. It was replaced in 1887 by a larger structure. The County Board of Supervisors authorized its construction, at a cost not to exceed $5,000 (the maximum amount the county was authorized to commit). To keep within this limit, members of the new community agreed to haul the building materials without charge from railroad stops at Sanborn and Paullina. The present courthouse was completed in 1917, and is listed on the National Register of Historic Places.

Geography
According to the United States Census Bureau, the county has a total area of 573 sqmi, of which 573 sqmi is land and 0.2 sqmi (0.03%) is water.

Roosevelt during his two nationwide landslides in 1932 and 1936. Since 1952, the Republican candidate has carried O'Brien County by a margin of at least 20% in every election except for 1964, when Democrat Lyndon B. Johnson only lost the county by 41 votes amidst a nationwide Democratic landslide.

Muscatine County, Iowa

Muscatine County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 43,235. The county seat is Muscatine. The southeastern border is formed by the Mississippi River. Muscatine County comprises the Muscatine, IA Micropolitan Statistical Area, which is included in the Davenport-Moline, IA-IL Combined Statistical Area.

History
Muscatine County was formed in December 1836 as a part of Wisconsin Territory, partitioned from Des Moines County, which had been organized two years previously. One history suggests that the county was named for Muscatine Island in the Mississippi River. The island lies opposite Muscatine County and was believed to be named after the Mascouten tribe, Algonquian-speaking Native Americans who lived in the area before being driven west by settler encroachment and other tribes.

Colonel George Davenport of Illinois sent three representatives into the territory in 1833 to establish a trade post. They were the first European Americans to settle there. In the same year, James W. Casey and John Vanatta came to the area. They opened a supply depot for steamboats on June 1, 1833, and named it Casey's Woodpile (since steamboats used wood as fuel). Muscatine County became part of Iowa Territory on July 4, 1838, when it was established by partitioning the area from Wisconsin Territory. The first public land sale was held in November 1838. One year later, officials began construction of the first courthouse and associated jail. A second jail, known as the "Old Jail", was built in 1857.

The first courthouse was destroyed by fire on December 23, 1864. By 1866 a replacement stood on the same site. The present courthouse opened on September 26, 1907.

Monona County, Iowa

Monona County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 8,751. The county seat is Onawa.

History
The area around present-day Onawa was a stopping point in 1804 for Meriwether Lewis and William Clark during their exploration of the newly obtained Louisiana Purchase. Many years later, that site was memorialized as the Lewis and Clark State Park.

Monona County was formed in 1851. It was perhaps named for an Indian word meaning "beautiful valley."

Monona County was organized officially in the spring of 1854 having been a part of Benton County (every county west of Benton in a line) in 1851 and afterwards Harrison County between 1852 and 1854.

When Ashton (originally called Bloomfield) was named the county seat in the fall of 1854, a log house served as the first courthouse. Ashton remained the county seat for only four years.

Politics
For over a century, Monona County was close to a national bellwether. Between 1900 & 2004, it only failed to back the national winner in 1960 & 1988. However, this bellwether status no longer applies. Barack Obama failed to carry the county in both of his electoral victories statewide & nationally, while Donald Trump in 2020 earned the highest percentage of any candidate since Franklin D. Roosevelt in 1932, in spite of his unsuccessful reelection bid.

History
The future county's first permanent settlement was Rushville, founded in 1846 by persecuted members of the Church of Jesus Christ of Latter-day Saints as they were being driven out of Nauvoo, Illinois. This is not to be confused with the state's present-day Rushville in Jasper County. A nearby settlement, also founded by the Mormon settlers, was called Coonsville after Dr. Liberius Coons, one of the first arrivals. That settlement continued after the Mormons moved on; its name was changed to Glenwood in 1853.

In Glenwood, the first courthouse was a small frame building which served until 1857. It was replaced by a two-story building, which was enlarged in the 1900s and received a clock tower in 1910. In 1959 this building was replaced with the present building, dedicated on August 29, 1959.

Geography
According to the U.S. Census Bureau, the county has a total area of 441 sqmi, of which 437 sqmi is land and 3.2 sqmi (0.7%) is water.

Roosevelt in 1932 and 1936, and for Lyndon B. Johnson in his 1964 landslide, who even then barely took Mills County by only 39 votes and less than 1%.

The first courthouse was completed in January 1846. When a larger structure was required, the second courthouse was constructed in 1885–86, first being used on February 27, 1886. The first school, a small log cabin one-half mile (ca. 2 km) east of Oskaloosa, was opened on September 16, 1844, and the Cumberland Presbyterian Church opened as the first church in 1846. On July 2, 1850, the first edition of the Iowa Herald was issued (today the Oskaloosa Herald). The first tracks of the Des Moines Valley Railroad were laid through the county in 1864.

Coal mining was once a major industry in Mahaska County. During the 19th century, Muchakinock, about 5 mi south of Oskaloosa, was probably the largest and most prosperous coal camp in Iowa.

Politics
For most of its history, Madison County has primarily supported the Republican Party in presidential elections. From 1880 to 1960, the county only failed to back the party's candidate in 1932 when Herbert Hoover was defeated in a national landslide for reelection by Franklin D. Roosevelt. The county was much more of a swing area between 1964 & 1996, voting for the national winner in every presidential election between 1964 & 2004 aside from 1988 when Michael Dukakis was boosted to an inflated margin of victory statewide by a farm crisis. Since the start of the second millennium, Republicans have carried the county in every presidential election. Donald Trump also produced the county's strongest Republican presidential victory since 1952 in 2016, winning by a margin of over 30 percent.

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.

Geography
According to the U.S. Census Bureau, the county has a total area of 588 sqmi, of which 588 sqmi is land and 0.1 sqmi (0.02%) is water.

Lyon County is the location of Gitchie Manitou State Preserve, which contains some of the oldest exposed bedrock in the country.

Lake Pahoja is located in the northwest part of the county. It is a man-made lake with an area of just over 28 ha.

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 his 1932 and 1936 landslides. 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.

Louisa County became a part of Iowa Territory upon its formation on July 4, 1838.

The first courthouse was a simple wood-framed building. In 1840, a second courthouse, measuring 40' x 20' (about 12 x 6 m), was constructed of stone. In 1854, a third structure was built. The courthouse used today was erected in 1928.

Linn County, Iowa

Linn County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 230,299, making it the second-most populous county in Iowa. The county seat is Cedar Rapids. Linn County is named in honor of Senator Lewis F. Linn of Missouri. Linn County is included in the Cedar Rapids, IA Metropolitan Statistical Area.

History
The earliest inhabitants of Linn County, prior to Anglo settlement, were the Sac and Fox tribes. Relations were described by 20th century historians as amicable. Native Americans provided food and furs to whites in exchange for merchandise.

Linn County was created as a named but unorganized area on December 21, 1837, as a part of Wisconsin Territory. It became part of Iowa Territory on July 4, 1838, when the territory was organized. Linn County was organized by the first legislative assembly of the Iowa Territory on January 15, 1839. A site was selected for its first county seat along Indian Creek, and was named Marion, after the Revolutionary War general Francis Marion. As early as 1855, there were debates over moving the county seat to the fast-growing Cedar Rapids, southwest of Marion, but it was not until November 6, 1919, that there were enough votes in favor of the move (9,960 to 4,823). The first rail line was built through Cedar Rapids in 1859, and made the town (and the county) a major commercial hub in eastern Iowa.

Many areas of the county were damaged by the flooding of Cedar River in June 2008, and again during the August 2020 Midwest derecho.

Geography
According to the U.S. Census Bureau, the county has a total area of 725 sqmi, of which 717 sqmi is land and 7.6 sqmi (1.1%) is water.

Lee County, Iowa

Lee County is the southernmost county in the U.S. state of Iowa. As of the 2020 census, the population was 33,555. The county seats are Fort Madison and Keokuk. Lee County is part of the Fort Madison–Keokuk, IA–IL–MO Micropolitan Statistical Area. It was established in 1836.

History
Fort Madison dates to the War of 1812. Lee County was the location of the Half-Breed Tract, established by treaty in 1824. Allocations of land were made to American Indian descendants of European fathers and Indian mothers at this tract. Originally the land was to be held in common. Some who had an allocation lived in cities, where they hoped to make better livings. Lee County as a named entity was formed on December 7, 1836, under the jurisdiction of Wisconsin Territory. It would become a part of Iowa Territory when it was formed on July 4, 1838. Large-scale European-American settlement in the area began in 1839, after Congress allowed owners to sell land individually. Members of the Church of Jesus Christ of Latter-day Saints (LDS Church) under the direction of Brigham Young fled persecutions in Missouri to settle in Illinois and Iowa. Nauvoo, across the border in Hancock County, Illinois, became the main center of Latter-day Saints settlement, but there was also a Latter Day Saints stake organized in Lee County under the direction of John Smith, the uncle of Joseph Smith, land that was sold to them by Isaac Galland in 1839.

Lee has two county seats—Fort Madison and Keokuk. The latter was established in 1847 when disagreements led to a second court jurisdiction. Lee County's population grew to about 19,000 in 1850, the first US census, to 37,000 per the 3rd census in 1870, peaking at 44,000 people in 1960. It has continuously decreased since and as of 2020, 33,555 people lived there, comparable to the years between 1860 and 1870.

Name
There is no consensus about the derivation of the name "Lee." It has been variously proposed that the county was named for Marsh, Delevan & Lee, of Albany, New York, and the 'New York Land Company', who owned extensive interests in the Half-Breed Tract in the 1830s; Robert E. Lee, who surveyed the Des Moines Rapids; or Albert Lea, who helped explore the interior of Iowa.

Geography
According to the U.S. Census Bureau, the county has a total area of 539 sqmi, of which 518 sqmi is land and 21 sqmi (4.0%) is water. The lowest point in the state of Iowa is located on the Mississippi River in Keokuk in Lee County, where it flows out of Iowa and into Missouri and Illinois.
