Cambridge is a village in Henry County, Illinois, United States. The population was 2,160 at the 2010 census, down from 2,180 in 2000. It is the county seat of Henry County. History Before 1843, the land where Cambridge is currently located was the private property of a man named Rev. Ithamar Pillsbury, who was very well known amongst the Yankee settlers (migrants from New England and upstate New York who were descended from the English Puritans who settled New England in the 1600s) who were moving to Henry County in large numbers at that time. Reverend Pillsbury deeded a large portion of his land to the town council and they immediately agreed it was a good place to lay out a town. Lots were sold to incoming migrants and on June 9 of 1843 (after some quarreling among the town founders about how to finance it) construction began on the town. Roads were laid out, post routes established, public buildings erected and people were invited to move there. The original settlers were entirely of New England origins or were Yankees from upstate New York whose families had moved to that place from New England only one generation earlier, in the aftermath of the Revolutionary War. This resulted in Henry County being culturally very contiguous with early New England culture.
