The Dakota Territory legislature created the county on January 4, 1873, with area partitioned from Pembina County. It was named for Morgan T. Rich, who settled on the site of the future Wahpeton in 1869. The county organization was completed on November 25 of that same year. Its boundaries were altered in 1883 and 1885. It has maintained its present configuration since 1885.  
Richland County lies at the SE corner of North Dakota. Its eastern boundary line abuts the western boundary line of the state of Minnesota (across the Red River), and its south boundary line abuts the north boundary line of the state of South Dakota. The Red River flows northerly along its eastern boundary line on its way to the Hudson Bay. The Wild Rice River flows easterly and then northerly through the county, discharging into the Red River north of Richland County, in Cass County. The Sheyenne River flows northeasterly through the NW corner of the county, also discharging into the Red in Cass County.
The Richland County terrain consists of verdant hills, sprinkled with lakes and ponds. It is largely devoted to agriculture.  The terrain slopes to the north and east, with its highest point near its SW corner, at 1,220' (372m) ASL.  The county has a total area of 1,445 square miles (3,740 km2), of which 1,436 square miles (3,720 km2) is land and 9.7 square miles (25 km2) (0.7%) is water.
