Kidder County, North Dakota: History
The Dakota Territory legislature created the county on January 4, 1873, with areas partitioned from Buffalo County. The county government was not organized at that time, nor was the area attached to another county for administrative or judicial purposes. It was named for Jefferson Parrish Kidder, a delegate to the United States Congress from Dakota Territory (1875–1879) and associate justice of the territorial supreme court (1865–1875, 1879–1883). The county government was affected on March 22, 1881.
The county boundaries were altered on 1879 with territory partitioned to Burleigh, and in 1885 with territory partitioned from Burleigh County. Its boundaries have remained unchanged since 1885.
