During the election on November 8, 1910, the voters ofWilliams County determined that the county should be divided into a northern and a southern county. The vote was affirmative; the southern portion retained the Williams name; the newly created county was named "Divide", with Crosby as the seat. The county government was effected on December 9 of that year, and the county's boundaries have remained unchanged since that time. Most histories attribute the county name to its "division" from Williams County,[4] though the county's location on theLaurentian Divide, separating runoff waters betweenHudson Bay andGulf of Mexico, may have been involved.[5]
In 1911, Divide County was the site of one of the deadliest tornadoes in North Dakota's recorded history, causing four known deaths.[6]
