# Phelps County, Missouri

Phelps County is a county in the central portion of the U.S. state of Missouri. As of the 2020 United States census, the population was 44,638. The largest city and county seat is Rolla. The county was organized on November 13, 1857, and was named for U.S. Representative and Governor of Missouri John Smith Phelps.
According to the U.S. Census Bureau, the mean center of U.S. population in 2000 fell within Phelps County.
Phelps County comprises the Rolla, Missouri Micropolitan Statistical Area. Much of the county is included within the Ozark Highlands American Viticultural Area (AVA). Vineyards and wineries were first established in the county by Italian immigrants in Rolla. Since the 1960s, winemakers have revived and created numerous vineyards in Missouri and won national and international tasting awards.
The first Phelps County Court convened on November 25, 1857, in the John Dillon cabin. The historic courthouse was begun in mid-summer of 1860, used as a Union hospital during the American Civil War and served as the courthouse until February 1994, when all county offices were relocated into the new Phelps County Courthouse, which was dedicated on May 22.

## History

Settlers of European descent established farms along the riverbanks in this area in 1818–1819.
One year later, Lieutenant James Abert started the first railroad reconnaissance survey in Rolla. Abert was later to become the first professor of Civil Engineering at the Missouri School of Mines. The founder of Rolla, Edmund Ward Bishop, was originally a railroad construction contractor in New York. He came to this part of the country in 1853, tasked with building the “Frisco Branch of the Southwest Railroad.”
Because of an urgent demand, Phelps County was created by legislative action on November 13, 1857, from portions of Pulaski, Maries and Crawford counties. A special commission was appointed to select a county seat, with instructions to locate the site on the mail line of the railroad as near as possible to the county's center. Bishop then offered a tract of some 50 acres (200,000 m$^2$) for the official town site, and it was accepted. There was disagreement over the site - the "westerners" wanted Rolla, and the "easterners" wanted Dillon, so the General Assembly did not legally declare Rolla to be the official county seat until 1861. The 600-strong group that favored Dillon signed a protest citing the fact that only two of the three commission members had met to consider the possible sites for the county seat. They contested the decision all the way through the Missouri Supreme Court. Before the high court could make a decision, however, the Legislature took action on January 14, 1860, confirming the location of the county seat at Rolla. Smarting under a considerable amount of criticism concerning the matter, all members of the county court resigned during April 1858, but later withdrew their resignations. It was finally settled in favor of Rolla.
Rolla was officially surveyed, laid out and named in 1858. Bishop wanted to call it Phelps Center, since his house was the center of the county. John Webber preferred the name "Hardscrabble" for obvious reasons. George Coppedge, another original settler, and formerly of North Carolina, favored "Raleigh" after his hometown. The others agreed with Coppedge on the condition that it shouldn't have "that silly spelling, but should be spelled 'Rolla'. The county seat locating commission designated the area now known as Rolla to be the county seat.
The town of Rolla did not exist when the county was officially created (November 1857); only the houses of J. Stever and John Webber were located in the area. Early court business included the location and opening of roads from the county seat to various places within the state, including St. Louis, Springfield, Jefferson City, Lake Spring, and Salem. It is in this last road order, dated in July 1858, that the use of the name Rolla first appears in the court records. The name was used earlier, in May 1858, in a deed of railroad land to the county.
On April 26, 1859, the county court ordered the 50 acres (200,000 m$^2$) donated by Mr. Bishop for the site of the county seat to be surveyed. The survey was conducted by A.E. Buchanan, a young railroad surveyor. Buchanan delivered his plat to the county court on May 31, 1859.

### Civil War

The railroad ran its first train on December 22, 1860, making Rolla the terminus of the road. Until the continuation of the Frisco, all goods were loaded on wagons and transported to Springfield and south and west on what is now U.S. Highway 66 (Interstate 44). During the American Civil War, Rolla was an important military post, hosting up to 20,000 Union troops. The Phelps County Court House was transformed into a hospital during the war.
In April 1861, Fort Sumter was fired upon and a decision was made to support the South. On May 10, the Circuit Court session saw a heated debate of secession, which caused a breakup of the proceedings. As the story goes, Circuit Court Judge James McBride soon departed to assume command as a Confederate general under Sterling Price. Outside the courthouse, a group of men drew down the United States flag and raised a Confederate flag, which had been hastily pieced together by the women of Rolla. The tension was thick when the group then moved to the newspaper office of Charles Walder, a Union supporter and editor of the Rolla Express. Walder was forced to close his shop and cease printing. Southern sympathizers patrolled the town day and night, often ordering Union sympathizers to leave town.
On June 14 of that year, General Franz Sigel arrived by train with his 3rd Missouri Infantry and took over the town. From that day until the close of the war, Rolla was in Union hands.
The 13th Illinois Infantry Regiment, under Colonel John B. Wyman, was brought in to guard Rolla and the Pacific Railroad's terminal. It was this regiment that did the basic planning and building of Fort Wyman, although other regiments completed it. President Abraham Lincoln’s personal order was that Rolla should be held at all costs. Being situated at the terminus of the railroad, military wagon trains went out from Rolla to all Union armies stationed southwest in Arkansas, Hartville, and Springfield and northwest to the Linn Creek area, now known as Lake of the Ozarks.
After General Price's defeat at Pea Ridge in March 1862, several troops that were organized by Governor Jackson returned home. Confederate sympathizers, unwilling to profess their loyalty and support to the Union after the battle, were treated harshly. One example is the shooting of former Presiding Justice Lewis F. Wright and four of his sons in 1864, after being taken from their homes for "questioning."
Rolla was an important site during the Civil War because the southwest branch of the Pacific Railroad ended here. Thousands of Union troops and their supplies came to Rolla by train from St. Louis and then were transferred to wagon trails to go to the battles of Wilson Creek in Springfield and Pea Ridge and Prairie Grove in Arkansas, plus a number of other smaller skirmishes. The railroad had arrived in Rolla in 1860 but the outbreak of the war halted the westward expansion of the line.
The town of about 600 civilians had a large population of Union troops at that time. Since the Union forces seized control of the town early in the war, they had a big impact upon the town and its operation.
The town was a busy place for the visitor. In 1860 sugar sold for 10 cents a pound, tobacco for 30 cents a pound. Whiskey went for 25 cents a gallon. City lots sold for $25 per lot. The Courthouse was used as a hay storage barn and later as a hospital for wounded soldiers. After the commanding general of the Union Forces, General Nathaniel Lyon, was killed at the Wilson's Creek battle near Springfield, his body was brought to Rolla to be transported back East for burial. Old town Rolla was located along Main Street near the Courthouse. The business district moved to Pine Street in the late 19th century.
Following the Union defeat at Wilson's Creek on August 10, 1861, the Union Army fell back to Rolla and began building an earthen fort on a hill alongside present Highway 63 about a mile from the Courthouse. The rectangular fort had a dry moat around the perimeter with 32-pound field pieces located on each corner of the fort to cover any attack on Rolla from the south. It was named Fort Wyman after Colonel John B. Wyman. Fort Dette was a more detailed fort that was constructed in 1863 on what is now the campus of Missouri University of Science and Technology. It was constructed in a cross shape with positions for both 24-pound cannons and ports for individual rifle fire.

### University

The Morrill Land-Grant College Act was approved by the U.S. Congress in 1862, and in 1863 the Missouri Legislature accepted this opportunity to set up a new type of higher education within the state. The act specified that the "leading object shall be without excluding other scientific and classical studies, and including military tactics, to teach such branches of learning as are related to agriculture and mechanics arts...in order to promote the liberal and practical education of the industrial classes in the several pursuits of professions of life."
The Missouri School of Mines and Metallurgy was founded in 1870 because the area was rich in minerals and because the geographic location was good. Phelps County bid $130,545, including lands and bonds, and was awarded the prize. Today it is named Missouri University of Science and Technology or Missouri S&T and is known as one of the finest engineering schools in the world. Not confined to mining and metallurgy, it confers bachelor's degrees in 23 fields of engineering and science, as well as graduate degrees in 28 fields of engineering and science.

### Other towns

Other towns within the county included Newburg, incorporated in 1888, and St. James, incorporated in 1869. Arlington and Jerome were both incorporated in 1867, but neither is incorporated at this time. Doolittle, the last of Phelps County's towns to be formed, was incorporated on July 2, 1944. Other Phelps County communities include Edgar Springs which was incorporated during the 1970s.

#### Political culture

At the presidential level, Phelps County is a fairly Republican-leaning county despite containing a relatively large university. George W. Bush easily carried Phelps County in 2000 and 2004. Bill Clinton was the last Democratic presidential nominee to carry Phelps County in 1992, and like many of the rural counties throughout Missouri, Phelps County favored John McCain over Barack Obama in 2008. It moved even further to the Right when it voted at record numbers for Donald Trump in 2016 and 2020. Trump received the most votes any candidate ever has, in Phelps county—for President—in 2020, and took 68% of the vote. In 2024, Trump became the first Republican in history to achieve over 70% of the vote, something that only one person had achieved before, that being Franklin D. Roosevelt during his overwhelming landslide in 1932.
Like most rural areas throughout central Missouri, voters in Phelps County generally adhere to socially and culturally conservative principles which tend to influence their Republican leanings. In 2004, Missourians voted on a constitutional amendment to define marriage as the union between a man and a woman—it overwhelmingly passed Phelps County with 77.94 percent of the vote. The initiative passed the state with 71 percent of support from voters as Missouri became the first state to ban same-sex marriage. In 2006, Missourians voted on a constitutional amendment to fund and legalize embryonic stem cell research in the state—it failed in Phelps County with 52.25 percent voting against the measure. The initiative narrowly passed the state with 51 percent of support from voters as Missouri became one of the first states in the nation to approve embryonic stem cell research. Despite Phelps County's longstanding tradition of supporting socially conservative platforms, voters in the county have a penchant for advancing populist causes like increasing the minimum wage. In 2006, Missourians voted on a proposition (Proposition B) to increase the minimum wage in the state to $6.50 an hour—it passed Phelps County with 69.42 percent of the vote. The proposition strongly passed every single county in Missouri with 78.99 percent voting in favor as the minimum wage was increased to $6.50 an hour in the state. During the same election, voters in five other states also strongly approved increases in the minimum wage.
