The First Wheeling Convention
- May 13-15 - Four-hundred thirty-six elected delegates from 17 Virginia counties met in Wheeling at Washington Hall. Several delegates had attended the General Assembly at Richmond. John S. Carlile of Harrison County insisted that the convention had the authority to take action on separation. Delegates formed a Committee on Credentials and a Committee on State and Federal Relations.
Calling for the state of "New Virginia," Carlile argued that Virginia must consent to the separation before it seceded from the Union. He felt that this was the only way to comply with Section Three of Article Four of the U.S. Constitution, which outlines the procedure by which one state is created from another.
The Committee on State and Federal Relations recommended that a new state not be formed at this time and advised waiting for the results of the May 23 referendum
The State Referendum on Secession

- June 20- Convention delegates signed the "Declaration of Rights of the People of Virginia" and elected Francis H. Pierpont Governor of the Restored Government of Virginia.

- Aug. 20-21 - The Committee of the Division of the State proposed a 39-county state known as "Kanawha." The convention adjourned Aug. 21.

- May 13 - The assembly approved the creation of West Virginia with 48 counties.
- May 29 - Sen. Waitman T. Willey submitted the application by West Virginia for admission to the Union to the U.S. Senate. Sen. John S. Carlile drafted the Senate bill but waited until the end of the congressional session to submit it. His bill called for the addition of 15 counties, which supported the confederacy, a new constitutional convention to approve this revision, and the emancipation of slave children born after 1863.

- Dec. 31 - President Lincoln signed the bill with these remarks: "The division of the State is dreaded as a precedent. But a measure made expedient by war is no precedent for times of peace. It is said that the admission of West Virginia is secession and tolerated only because it is our secession. Well, if we call it by that name there is still difference enough between secession against the Constitution and secession in favor of theConstitution. I believe the admission of West Virginia into the Union is expedient."
