What pushed West Virginia to break way from Virginia and create a new state?

West Virginia separated from Virginia during the Civil War primarily due to political and economic differences. The western counties of Virginia were less reliant on slavery and had different economic interests, leading to tensions with the eastern regions. The conflict intensified when Virginia seceded from the Union in 1861; many in the west opposed secession. This culminated in the formation of West Virginia as a separate state in 1863, recognized for its loyalty to the Union.
