Iowa’s history is a tapestry of Indigenous heritage, European exploration, pioneering settlement, agricultural development, and political significance. Bordered by the Mississippi and Missouri Rivers, Iowa evolved from a land shaped by ancient glaciers and Indigenous civilizations into a vital economic and cultural crossroads of the American Midwest. From the days of the Paleo-Indians through its territorial expansions and statehood, Iowa has continuously adapted—reflecting both its rural roots and its forward-looking innovation.
