History of Iroquois County

Iroquois County was created on February 26, 1833, out of a portion of Vermilion County. It was named for the Iroquois River, which was itself named for the Iroquois people. The first county seat was established at the town of Iroquois in 1837, though no official buildings were constructed there and offices were rented. Several other sites for the county seat were examined, and in 1839 it was moved to Middleport; a court house and jail were built there. There was a long battle between Middleport and Watseka (also known as South Middleport) as to which should be the county seat; in 1865, it was finally moved to Watseka. The town of Middleport no longer exists, but there is a township of that name.
