West Virginia was recognized by the United States government as the thirty-fifth state on June 20, 1863, an event that was the culmination of more than sixty years of heated sectional politics and legislative maneuverings. From the first political rumblings of new-state advocates at the turn of the nineteenth century through the formative sessions of the Wheeling conventions held from 1861 until 1863, the creation of West Virginia was a complex and contentious process that divided the residents, communities, and political leaders of Virginia. Spearheaded by northwestern Virginians, the statehood movement began as an effort to expand western political influence and the region's growing industrial economy. Final approval of West Virginia's statehood was forged amid the chaos and divisiveness of the secession debate and the bloodshed of the American Civil War (1861–1865).
