McHenry County was formed in 1836 out of Cook and LaSalle Counties. The County was named for Major William McHenry, an old Indian fighter who died in Vandalia in 1835.McHenry County originally stretched all the way east to Lake Michigan, with the county seat centrally in McHenry, but in 1839, the eastern townships of the county were carved out to form Lake County.
The Republican Party has maintained McHenry County as one of its most reliable strongholds, being the most conservative county in Chicagoland.
