Drew County was formed on November 26, 1846, and named for Thomas Drew, the 3rd governor of Arkansas. Located on the edge of the Arkansas Timberlands and the Arkansas Delta, its fertile soils produced prosperity for early settlers in the antebellum era. Cotton was the major commodity crop, but corn, apples, peaches and tomatoes were also grown. Following the Civil War, the boundaries of Drew County changed. In the late 19th and early 20th centuries, timber harvesting became an important industry. As a variety of industries began to move to the county, several colleges were founded in the county in the early part of the 20th century, one developing as University of Arkansas at Monticello. Today the county has a diverse economy and is an economic center in southeast Arkansas."
