Marshall County, Minnesota: History
The Minnesota legislature created the county on February 25, 1879, with territory partitioned from the southern half of Kittson County, with Warren (which was first platted that same year) as the county seat. It was named for William Rainey Marshall, who served as Minnesota governor from 1866 to 1870.
Until May 1965, when county option was eliminated, Marshall County was a dry county; no beverages with over 3.2% alcohol could be sold.
Marshall County was the location of a claimed UFO incident in 1979, the Val Johnson incident.
