# Franklin County, Missouri

Franklin County is located in the U.S. state of Missouri. At the 2020 census, the population was 104,682. Its county seat is Union. The county was organized in 1818 and is named after Founding Father Benjamin Franklin. Franklin County is part of the St. Louis, MO-IL Metropolitan Statistical Area and contains some of the city's exurbs. It is located along the south side of the Missouri River. The county has wineries that are included in the Hermann AVA (American Viticultural Area) and is part of the region known as the Missouri Rhineland, which extends on both sides of the Missouri River.

## History

Occupied by succeeding cultures of indigenous peoples, this area was populated by the historic Osage tribe at the time of European encounter. The region was first settled by Europeans during the rule of the Spanish Empire. The Spanish log fort San Juan del Misuri (1796–1803) was built in present-day Washington. After the American Revolutionary War, migrants from the new United States started moving West. Among them were the family and followers of Daniel Boone, an explorer from Kentucky who settled the area starting in 1799. For the next two decades, most settlers came from the Upper South, especially Kentucky and Virginia, bringing their slaves with them to work the land.
In 1833 substantial numbers of German immigrant families began settling in the area, and soon they outnumbered the slave owners in the county. The German newcomers were opposed to slavery, and their sons would become Union supporters during the U.S. Civil War. Former governor and then Confederate General Sterling Price led his cavalry through the county during his Missouri raid of 1864.
Before the war Franklin County had been served by steamboats that moved freight and passenger traffic on the Missouri River. Afterwards, it became a railroad transportation center. Manufacturing industries were established at the end of the Civil War and successive ones have continued.
Bias Vineyard, near the small city of Berger, is located within the Hermann American Viticultural Area (AVA), designated in 1983. Röbller Vineyard and Winery near New Haven is also in the Hermann AVA. Wineries along both sides of the Missouri River are part of the Missouri Rhineland, whose vineyards were started by German immigrants in the mid-19th century. Before Prohibition, Missouri was the second-largest wine-producing state in the nation. Everything was closed down except for limited production of wine allowed for religious purposes. The state's wine industry had to be completely rebuilt, which has been taking place since the 1960s.
The rural county has had severe problems with local production, distribution and consumption of methamphetamine. The struggles of the county with adverse effects of the drug, was explored in a 2005 A&E documentary entitled Meth: A County in Crisis.

## Geography

According to the U.S. Census Bureau, the county has a total area of 931 square miles (2,410 km$^2$), of which 923 square miles (2,390 km$^2$) is land and 8.0 square miles (21 km$^2$) (0.9%) is water. It is the fourth-largest county in Missouri by land area and third-largest by total area.
The center of the Missouri River forms the nominal northern border of the county, although the river has changed its course since boundaries were first established: a portion of St. Charles County near St. Albans is now south of the river, while a portion of Franklin County near Augusta is north of the river.
The Bourbeuse River flows for 107 miles through the county. It cuts a deep, narrow valley and is very crooked. It empties into the Meramec River near Union. This river is mostly undeveloped, with limited access and few bridges over it. During low water, a number of fords allow crossing.
The county is located in the Ozarks region, with steep hills and deep valleys, caves, springs, and sinkholes characteristic of karst areas. The underlying rock is typically carbonate, including limestone and dolomite. Mining activity in the county included ores of lead, copper, zinc, and deposits of refractory clay. The soils in most of the county tend to be thin, rocky red clay, and are poor for most agriculture, while the soil near the Missouri River is dark, rich, and thick, and used primarily for row crops such as corn, wheat, and soybeans. Much of the county is covered with thick forests, reestablished since the 1920s.
Urbanization is increasing in the county, especially surrounding Washington and Union, and along Interstate 44. St. Albans is now a continuation of the suburban region of St. Louis County while the majority of the county retains a rural character and includes extensive wilderness areas, typical of exurban areas.

At the presidential level, Franklin County is fairly independent-leaning, but, like many exurban and mostly rural counties, its voters often favor Republican and conservative issues. While southerner Bill Clinton narrowly carried the county both times in 1992 and 1996, George W. Bush strongly carried Franklin County in 2000 and 2004. Like many of the rural counties in Missouri, Franklin County favored John McCain over Barack Obama in 2008.
Like most predominantly rural areas, voters in Franklin County generally strongly support socially and culturally conservative principles and therefore tend to support Republican candidates. In 2004, Missourians voted on a constitutional amendment to define marriage as the union between a man and a woman; the measure overwhelmingly passed Franklin County with 76.89 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 Franklin County with 56.13 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 Franklin County's longstanding tradition of supporting socially conservative platforms, voters have advanced some populist causes such as 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 Franklin County with 77.61 percent of the vote. The proposition strongly passed every single county in Missouri with 75.94 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.
