## History

[edit]

### Early history

[edit]

See also: History of Kansas

For many millennia, the Great Plains of North America was inhabited by nomadic Native Americans. From the 16th century to 18th century, the Kingdom of France claimed ownership of large parts of North America. In 1762, after the French and Indian War, France secretly ceded New France to Spain, per the Treaty of Fontainebleau.

### 19th century

[edit]

In 1802, Spain returned most of the land to France, but keeping title to about 7,500 square miles. In 1803, most of the land for modern day Kansas was acquired by the United States from France as part of the 828,000 square mile Louisiana Purchase for 2.83 cents per acre.

In 1854, the Kansas Territory was organized, then in 1861 Kansas became the 34th U.S. state. In 1855, Jefferson County was established, and was named for President Thomas Jefferson.[4] Settlement of the county was slowed by events prior to and during the Civil War, but the present day unincorporated community of Thompsonville (3 miles northwest of Perry on the Delaware River) was the first established in 1851 by Mormon settlers who initially refused to accompany the main group led by Brigham Young to the Salt Lake Valley. The settlement was first abandoned due to the violence resulting from the border wars, but was re-established when the Civil War ended.[citation needed]

Like all of Kansas outside the eastern cities, Jefferson County is a Republican stronghold, having not been won by a Democrat since Franklin D. Roosevelt’s 1932 landslide – although it was one of three Kansas counties to give a plurality to Ross Perot in 1992.

### Laws

[edit]

Jefferson County was a prohibition, or "dry", county until the Kansas Constitution was amended in 1986 and voters approved the sale of alcoholic liquor by the individual drink with a 30% food sales requirement.[12]

The county voted "No" on the 2022 Kansas abortion referendum, an anti-abortion ballot measure, by 55% to 45% despite backing Donald Trump with 65% of the vote to Joe Biden's 33% in the 2020 presidential election.[13]

## Media

[edit]

Jefferson County has two newspapers which are still in operation, The Oskaloosa Independent and The Valley Falls Vindicator. Both of which are owned by Davis Publications.[14] Together, the two papers cover the happenings of Jefferson County and its townships. The editor for both papers is Holly Allen.
