Montgomery County came into being in 1793 when the state legislature set aside land from Washington County. With the Revolutionary War still fresh in their minds, founders named this county for General Richard Montgomery who was mortally wounded at the siege of Quebec. Mt. Vernon, the county seat, is named for President George Washington's home on the Potomac River.
Almost 53% of the county's land is in farms. Only 20 Georgia counties have a larger proportion of land area dedicated to farming.
