The state that would be formed due to the disagreement within Virginia is West Virginia. Here's an explanation:
1. Disagreements over slavery and political differences led to the formation of West Virginia during the American Civil War.
2. In 1863, the western counties of Virginia, which were more pro-Union and had different economic interests, broke away from Virginia and became the separate state of West Virginia.
3. West Virginia's admission to the Union was a result of these internal conflicts within Virginia, ultimately leading to the creation of a new state with its own government and identity.
This separation was a significant event in American history, showing how internal divisions can sometimes lead to the formation of new political entities.
