Grant County in West Virginia was formed from which county?

Grant County in West Virginia was formed from Hardy County. This historical formation took place in 1866, during the period of West Virginia's early statehood. Understanding the geographical and political context of the time is important, as counties often emerged from surrounding counties due to population growth, administrative needs, or changing political boundaries. In this case, the division of Hardy County allowed for the establishment of Grant County, which is named after Ulysses S. Grant, and reflects the post-Civil War sentiments prevalent during its creation. The other counties listed—Hampshire, Kanawha, and Clark—did not contribute to the formation of Grant County, making Hardy County the correct answer in this context.
