Cassia County is a county in the U.S. state of Idaho. As of the 2020 Census the county had a population of 24,655.[1] The county seat and largest city is Burley.[2] Cassia County is included in the Burley, ID Micropolitan Statistical Area.

History

The first Europeans explored the Milner area in Cassia County in 1811. It was trappers who initially developed the Oregon Trail, which ran on the county's northern border. The Raft River's junction with the Oregon Trail marked the split for the California Trail.

While the Oregon and California trails brought hundreds of thousands of emigrants through Cassia County, it also brought settlers. A stage line through the county was established between Kelton, Utah and Boise, Idaho in 1869. A stage station existed at City of Rocks. Additional stations were spaced at increments of 10–12 miles between stations to include one at Oakley Meadows, in the Goose Creek valley two miles west of the present settlement of Oakley.

William Oakley settled at the Oakley Meadows station in 1870. Cattle operations also developed starting in 1872. Settlement began at nearby Albion in 1873 with significant Mormon settlement in 1875. By 1880, Albion had a population of 257. Mormon settlement at Oakley also began on June 1, 1878, when four Mormon men each staked out 160 acres for their settlement. Settlements remained primarily agricultural with more than 38,000 head of cattle in the area by 1885. Settlement at Malta occurred prior to 1890, as the Malta precinct had 172 residents at the 1890 census.

Albion State Normal School was established at Albion in 1893. The school was focused on training Idaho teachers until 1951 when its programs were transferred to Idaho State College (now Idaho State University) in Pocatello.[3][4][5][6]

Burley was platted and settled in 1905 after a branch of the Oregon Shortline was constructed through the town. Declo was settled under the name of Marshfield by 1909.[7]

Cassia County was created from Owyhee County on February 20, 1879, with Albion becoming the county seat.[8] A western portion became Twin Falls County in 1907. The county assumed its present boundaries when an eastern portion became Power County on January 30, 1913. The county seat was moved to Burley in 1918. The county was named for Cassia Creek, which in turn was named either for John Cazier, a member of the Mormon Battalion and an emigrant train captain, or for a plant found in the area.

Government

Elected Officials

Similar to other Idaho counties, an elected three-member county commission heads the county government. Other elected officials include clerk, treasurer, sheriff, assessor, coroner, and prosecutor.

County Commission

Other Elected Officials

Cassia County is in Idaho's 2nd congressional district and represented by Congressman Mike Simpson. At the state level, Cassia County is in Legislative District 27, represented by Senator Kelly Anthon of Declo, Douglas Pickett of Oakley and Clay Handy of Burley.

Politics

At every level, Cassia County is a Republican Party stronghold. All county-level offices are held by Republicans and have been for decades. Republican primaries are tantamount to election to office, as Democrats rarely field challenges for county or state legislative office. Cassia County is one of the most consistently Republican counties in the state, and in the gubernatorial election of 2010 Republican Butch Otter carried Cassia County with 76.54% to Democrat Keith Allred's 16.73%.[9] In the presidential election of 2012, Mitt Romney, whose father lived for a few years in his youth in Oakley, carried Cassia County with 85.2% while Barack Obama received 13.1%.[10] The last Democratic presidential candidate to carry Cassia County was Franklin Roosevelt in the election of 1940 edging out Wendell Willkie by around 100 votes.

State legislators from Cassia County traditionally hold their seats for long periods of time. Two of the longest serving legislators in Idaho history were from Cassia County: Vard Chatburn of Albion who served in the House of Representatives from 1957 to 1986 and Denton Darrington in the Senate who served from 1982 to 2012. Because legislators rarely lose their seats, legislators representing Cassia County are often in leadership or chair committees. From 2012 to 2023, Representative Scott Bedke served as Speaker of the House. Bruce Newcomb of Burley also served as Speaker from 1998 to 2006.

Though born in Burley, Congressman Simpson now lives in Idaho Falls. The only other member of congress with ties to the county is Henry Dworshak who represented Idaho's 2nd congressional district and later served in the Senate. He lived in Burley and was the publisher of the Burley Bulletin. A Burley elementary school is named after him.
