History

The Dakota Territory legislature created the county on January 4, 1873. It was named for Joseph Renville, an influential fur trader, interpreter, translator, and important figure in dealings between white men and the Sioux. The county was not organized at that time, nor was it attached to another county for administrative or judicial purposes. The proposed county boundaries were altered in 1883, in 1885, and 1887, and on November 8, 1892, the county was dissolved and absorbed into Bottineau and Ward counties due to a lack of settlement. The general election held November 3, 1908 included a question asking whether a portion of Ward County should be partitioned off and named Renville County (covering a different area than the original county). This question reportedly failed to pass, but it was promptly contested in court, resulting in a ruling by the state Supreme Court ruled on June 3, 1910, that the split should be carried out. The state governor proclaimed the result in a July 12 proclamation, and the county government was organized on July 20 of that year, with Mohall as the county seat.
