As of the 2010 U.S. Census, the county is estimated to be home to 312,311 people,[1] an 84 percent increase over the 2000 figure of 169,599.

Its county seat is Leesburg.[2] As of 2007, the town had been county seat for 249 of the last 250 years.[3]

As of 2007, Loudoun County has the highest median household income of any county in the United States ($107,207), beating neighboring Fairfax County, Virginia ($105,241).[4] The two counties have been trading places as the highest-income county in the United States in recent years.

Loudoun County was established in 1757 from Fairfax County. The county is named for John Campbell, Fourth Earl of Loudoun and Governor of Virginia from 1756–59. Western settlement began in the 1720s and 1730s with Quakers, Scots-Irish, Germans and others moving south from Pennsylvania and Maryland and by English and African slaves moving upriver from Tidewater.

By the time of the American Revolution, it was the most populous county in Virginia. During the War of 1812, important Federal documents and government archives were evacuated from Washington and stored at Leesburg for safe keeping. Local tradition holds that these documents were stored at Rokeby House and thus that Leesburg was briefly the capital of the United States.

Early in the American Civil War, the Battle of Balls Bluff took place near Leesburg on October 21, 1861. Future jurist Oliver Wendell Holmes, Jr. was critically wounded in that battle along the Potomac River. During the Gettysburg Campaign in June 1863, Confederate Major General J.E.B. Stuart and Union cavalry clashed in the battles of Aldie, Middleburg, and Upperville. Confederate partisan John S. Mosby based his operations in Loudoun and adjoining Fauquier County (for a more in-depth account of the history of Loudoun County during the Civil War, see Loudoun County in the American Civil War).

Loudoun County is one of the most Republican-leaning counties in Northern Virginia. Prior to the 2008 election, it had not voted for a Democrat for President since Lyndon B. Johnson in 1964. In recent years, however, the county has experienced rapid growth in its eastern portion, driven mainly by commuters drawn by the close proximity to Washington, D.C. This has made Loudoun more competitive. Nevertheless, after giving Senator Barack Obama nearly 54% of its presidential vote in 2008, the county shifted back to the GOP in 2009; Republican Robert F. McDonnell received 61% of the gubernatorial vote. Voters also removed two incumbent Democratic delegates, making Loudoun's state House delegation all-Republican.

Like many counties in Virginia, Loudoun is governed by a board of supervisors. The Chairman of the Board is elected by county voters at-large while the remaining supervisors are elected from each of eight electoral districts. All nine members serve concurrent terms of four years. While the board handles policy issues and sets the budget, day-to-day operations of the county government are handled by a County Administrator appointed by the board. The 2003 board, among other officials in Loudoun, was the subject of a federal investigation of possible corruption relating to a land deal involving the Royal Saudi Academy.[7]

Board of Supervisors[]

In November 2007 voters removed four incumbent pro-growth Republicans from the existing Board of Supervisors in a backlash over rapid development in the eastern portion of the County. The make-up of the board following the election is five Democrats, two Republicans, and two Independents.[8]
