The state of Virginia's secession convention votes to secede from the United States, becoming the 8th state to join the Confederate States of America.

The American state of Virginia became a prominent part of the Confederacy when it joined during the American Civil War. As a Southern slave-holding state, Virginia held the state convention to deal with the secession crisis, and voted against secession on April 4, 1861. Opinion shifted after April 15, when U.S. President Abraham Lincoln called for troops from all states still in the Union to put down the rebellion, following the capture of Fort Sumter. The Virginia convention voted to declare secession from the Union on April 17. A Unionist government was established in Wheeling and the new state of West Virginia was created by an act of Congress from 50 counties of western Virginia, making it the only state to lose territory as a consequence of the war.

In May, it was decided to move the Confederate capital from Montgomery, Alabama, to Richmond, Virginia, in part because the defense of Virginia's capital was deemed vital to the Confederacy's survival. On May 24, 1861, the U.S. Army moved into northern Virginia and captured Alexandria without a fight. Most of the battles in the Eastern Theater of the American Civil War took place in Virginia because the Confederacy had to defend its national capital at Richmond, and public opinion in the North demanded that the Union move "On to Richmond!" The successes of Robert E. Lee in defending Richmond are a central theme of the military history of the war. The White House of the Confederacy, located a few blocks north of the State Capitol, became home to the family of Confederate leader, former Mississippi Senator Jefferson Davis.

Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population in 2020 was over 8.65 million, with 36% of them living in the Baltimore–Washington metropolitan area.

The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the growing plantation economy, but also fueled conflicts both inside and outside the colony. As one of the original Thirteen Colonies, during the American Revolution, it became part of the United States in 1776. During the American Civil War, Virginia was split when the state government in Richmond joined the Confederacy, but many of the state's northwestern counties wanted to remain with the Union, helping form the state of West Virginia in 1863. Although the Commonwealth was under one-party rule for nearly a century following the Reconstruction era, both major political parties are competitive in modern Virginia.

Virginia's state legislature is the Virginia General Assembly, which was established in July 1619, making it the oldest current law-making body in North America. It is made up of a 40-member Senate and a 100-member House of Delegates. The state government is unique in how it treats cities and counties equally, manages local roads, and prohibits governors from serving consecutive terms. Virginia's economy has many sectors: agriculture in the Shenandoah Valley; high tech and federal agencies, including the headquarters of the U.S. Department of Defense and Central Intelligence Agency, in Northern Virginia; and military facilities in Hampton Roads, the site of the region's main seaport.
