The western part of Maryland (including the present Allegany County) was incorporated into Prince George's County in 1696. This county included six current counties, and by repeated splitting, new ones were generated: Frederick from Prince George's in 1748; and Montgomery and Washington from Frederick in 1776.
Allegany County was formed in 1789 by the splitting of Washington County. At the time it was the westernmost county in Maryland, but a later (1872) split produced Garrett County, the current westernmost county.
