Union County is a county in southern Iowa. In 2020, about 12,138 people lived there. The main city and county seat is Creston.
The county was formed in 1853. It was named "Union" because people wanted to keep the United States together. This was a time of disagreement before the American Civil War. Union County had its largest population in 1900. Today, its economy mainly relies on farming and related businesses.

History of Union County
The first permanent settlers from Europe and America arrived in Union County around 1849 and 1850. Before them, Mormons had a stop called Mt. Pisgah. This was a resting place for Mormon pioneers traveling west. The Mormons left the area by 1848.
Later settlers used Mt. Pisgah as a base. They started farms along the Grand and Platte rivers. These rivers flow through the county. Farmers sold their crops to people traveling to California. Many were going there for the California Gold Rush. Travelers often stayed with the settlers. In 1851, one settler saw 2,600 wagons heading to California. People often brought sheep and cattle, hoping to sell them to miners.
The first village in the county was Petersville. It was founded in 1853, the same year the county was officially created. The county was named to show the desire for the "union" of states to stay strong.
Railroads and Growth
After the American Civil War, railroads were built in the county. This connected towns and helped farmers sell their goods. In 1868, the railroad reached Afton, Iowa. The next year, Creston became a major railroad hub. The railroad built repair shops and other buildings there.
The railroad brought many new people to the area. Immigrants came from Europe, and others moved from eastern U.S. states. They were drawn by the rich farmland. The Burlington Northern Santa Fe Railroad (BNSF) is still important today. It mainly carries grain and coal.
The Bluegrass Palace
Union County has a fair every year. In the late 1800s, this part of Iowa was known for its bluegrass. In 1889, the Bluegrass Association was started. It included representatives from 18 counties.
They built a special building called the Bluegrass Palace. It was located at the Union County Fairgrounds. The palace was designed by Louis Syberkro and built by J. C. Woodruff, both from Creston. It was made of sod and hay bales over a wood frame. The building was 100 feet wide and had a tall central tower. Inside, it showed off farm products and natural resources from the area. These included wood, coal, and stone.
The first palace was very popular. So, the next year, they built an even bigger one. It had three times more space. It also had a separate auditorium that could hold 2,000 people.
