Loudoun County was established in 1757 from Fairfax County. The county is named for John Campbell, Fourth Earl of Loudoun and Governor General 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 Virginia's most populous county. It was also rich in agriculture, and the county's contributions of grain to George Washington's Continental Army, earned it the nickname "Breadbasket of the Revolution."
During the War of 1812, important Federal documents and government archives were evacuated from Washington and stored at Leesburg. Local tradition holds that these documents were stored at Rokeby House, making Leesburg briefly the capital of the United States.
U.S. President James Monroe treated Oak Hill Plantation as a primary residence from 1823 until his death on July 4, 1831. The Loudoun County coat of arms and flag, granted by the English College of Arms, memorialize the special relationship between Britain and the United States that developed through his Monroe Doctrine.
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).
In 1962, Washington Dulles International Airport was built in southeastern Loudoun County in Sterling. Since then, Loudoun County has experienced a high-tech boom and rapid growth. Accordingly, many have moved to eastern Loudoun and become residents of planned communities such as Sterling Park, Sugarland Run, Cascades, and Ashburn Farms, making that section a veritable part of the Washington suburbs. Others have moved to the county seat or to the small towns and rural communities of the Loudoun Valley.

Loudoun County was traditionally a Republican-leaning county. Before the 2008 election, it had not voted for a Democrat for President since Lyndon B. Johnson in 1964. In recent years, the county's rapid growth in its eastern portion, driven mainly by commuters drawn by the close proximity to Washington, D.C., has made Loudoun more competitive. After giving Senator Barack Obama nearly 54% of its presidential vote in 2008, the county shifted back to the GOP in 2009; Republican Bob McDonnell received 61% of the gubernatorial vote. Voters also removed two incumbent Democratic delegates, making Loudoun's state House delegation all-Republican. Loudoun shifted back to the Democrats in 2012 in the presidential election, as Obama recaptured the county with 51.5%, with Republican challenger Mitt Romney garnering 47%. Democrats solidified their strength in the county in the 2016 presidential election, as despite Donald Trump's victory, Loudoun swung heavily towards Democrats, with Hillary Clinton garnering 55.1% to Trump's 38.2%.
Like many counties in Virginia, Loudoun is governed by a board of supervisors, the Loudoun County 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, a Board-appointed County Administrator handles the county government's day-to-day operations. 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.
In November 2007 voters removed four incumbent, fiscally conservative Republicans from the Board of Supervisors in a backlash over rapid development in the county's eastern portion. The Board's make-up after the election was five Democrats, two Republicans, and two Independents.
In November 2011, Republicans were elected to all nine seats on the Board.
September 6, 2015, Broad Run Supervisor Shawn M. Williams resigned after his arrest for assault.
