Prairie County has always been important to Arkansas for the transportation of people and goods throughout the state. Initially, it was the White River that gave the agricultural county its importance for transport, since waterways were the primary means of long-distance transportation in the period before the development of railroads. Prairie County was cut from Arkansas, Pulaski, Monroe, St. Francis, and White counties in 1846 and included present-day Lonoke County. European settlement in Prairie County came in the 19th century, with Jacob M. DeVall and his son, Chappel, becoming the first recorded settlers around DeVall's Bluff according to 1851 tax records.
