Mason County is a county in the U.S. state of Illinois. According to the 2010 census, it had a population of 14,666.[1] Its county seat is Havana.[2] The county is named in honor of George Mason, a member of the Virginia legislature who campaigned for the adoption of the United States Bill of Rights.

History[]

Mason County was created in 1841 out of portions of Tazewell and Menard counties.

Geography[]

According to the U.S. Census Bureau, the county has an area of 563 square miles (1,460 km2), of which 539 square miles (1,400 km2) is land and 24 square miles (62 km2) (4.3%) is water.[3]

Mason County is bound on the south by the Sangamon River, and on the west by the Illinois River. These rivers join at the county's southwest tip.

The soil covering much of Mason County is very sandy. This was formed during the melting of the Wisconsin Glacier about 10,000 years ago. Meltwater from the glacier deposited large amounts of sand in a delta region near at the junction of the Sangamon and Illinois Rivers.

The sandy soil does not hold water well, quickly exposing crops to drought conditions as the water table drops during periods of low precipitation. However, the soil is very good for growing vegetables that are otherwise not common in Illinois. Modern irrigation has made this a highly productive agricultural area.

A sand wetland on the Illinois River is managed by the U.S. Fish and Wildlife Service as the Chautauqua National Wildlife Refuge.

Politics[]

Although it voted for the Whig Party in the three elections from 1840 to 1848, Mason County was to be solidly Democratic for the next sixty to seventy years due to its anti-Yankee German-American heritage. It was not until the 1920 election when bitter resentment was felt by German-Americans at Woodrow Wilson’s postwar policies that Mason supported a GOP candidate.

In the following eighty years, Mason was a Republican-leaning swing county, although isolationist sentiment did cause it to vote narrowly for Wendell Willkie in 1940 and more convincingly for Thomas E. Dewey in 1944.
