On September 6, 1776, the Maryland Constitutional Convention agreed to a proposal introduced by Thomas Sprigg Wootton wherein Frederick County, the largest and most populous county in Maryland, would be divided into three smaller units. The southern portion of the county, of which Rockville was a part, was named Montgomery County. The most populous and prosperous urban center in this new county was George Town, but its location at the far southern edge rendered it worthless as a seat of local government. Rockville, a small, but centrally located and well-traveled town, was chosen as the seat of the county's government. At the time, Rockville did not have a name; it was generally called Hungerford's Tavern, after the well-known tavern in it. After being named the county seat, the village was referred to by all as Montgomery Court House. The tavern served as the county courthouse, and it held its first such proceedings on May 20, 1777.
