History of Arlington County (old Alexandria County)

Alexandria County, Virginia formed from the District of Columbia (that part which was formerly a part of Fairfax County and Alexandria City, Virginia). Extinguished in 1920 with formation of Arlington County. On Dec. 3, 1789, the Virginia Assembly passed 'An Act for the cession of ten miles square, or any lesser quantity of territory within this State, to the United States, in Congress assembled, for the permanent seat of the general government' ... By act of Congress of Feb. 27, 1801 (U. S. Stats. 2, pp. 103, 115), the United States took over exclusive jurisdiction of that portion of Fairfax County, therein named Alexandria County. By Act of Congress of July 9, 1846 (U.S. Stats. 9, p. 35), the United States retroceded to Virginia the territory comprising the County of Alexandria, and by Act of Assembly of Mar. 13, 1847... Virginia extended her jursidiction over the retroceded territory. [Virginia Counties: Those Resulting from Virginia Legislation, by Morgan Poitiaux Robinson, originally published as Bulletin of the Virginia State Library, Volume 9, January, April, July 1916, reprinted 1992 by Genealogical Publishing Co., Inc., Baltimore, MD, p. 74]

Arlington County was originally named Alexandria County. It was formed from a part of Fairfax County that was ceded to the U.S. government in 1789 but was returned to Virginia in 1846. The county name was changed in 1920 to Arlington, the name of the Custis family mansion (former home of Robert E. Lee), which is located in the county. Its area is 25 square miles, and the county seat is Arlington. The population is 189,453 according to the 2000 census. Pre-1920 records belong to Alexandria and Fairfax Counties and the District of Columbia.

The history of our nation was a prolonged struggle to define the relative roles and powers of our governments: federal, state, and local. And the names given the counties, our most locally based jurisdictions, reflects the "characteristic features of this country!"
