Johnston County was created in 1746 from Craven County and named in honor of Gabriel Johnston, North Carolina's royal governor at the time. Johnston County originally contained most of what is now Wake, Wayne, Greene, and Lenoir counties and part of Wilson. Johnston County has been an agricultural community since its founding. Agriculture is a valued and defining feature of the history, landscape, and culture of the county.
