"If any of their officers, or creatures, should attempt to oppress the people, or should actually perpetrate the blackest deed, he has nothing to do but get into the ten miles square. Why was this dangerous power given?" The "dangerous power" to which GEORGE MASON objected so vehemently at the Virginia ratifying convention was that vested in Congress by the seventeenth clause of Article I, section 8, "to exercise exclusive legislation in all cases whatsoever, over such district (not exceeding ten miles square) as may ? become the seat of the government of the United States." That the power to legislate for the capital district should be controversial was a surprise to JAMES MADISON, who had proposed it in the CONSTITUTIONAL CONVENTION OF 1787. He defended the provision as the means by which the federal government might "be

Alexandria was retroceded to Virginia in 1846, at the request of its inhabitants, and the district has since comprised less than seventy square miles. Since 1871, there has been a single municipal corporation coextensive with the district. The 1980 population of over 600,000 was larger than the populations of each of four states.
During most of its history the district's lawmaking was done directly by Congress. There was a brief period of home rule, under a government like those of the TERRITORIES, from 1871 to 1874, during which the district plunged deeply into debt. From 1878 until 1974 the district was governed by three commissioners appointed by the President. Home rule was restored by passage of...
