Joseph Martin, Jr. (1740–1808) was a brigadier general in the Virginia militia during the American Revolutionary War, in which Martin's frontier diplomacy with the Cherokee people is credited with not only averting Indian attacks on the Scotch-Irish American and English American settlers who helped win the battles of Kings Mountain and Cowpens, but with also helping to keep the Indians' position neutral and from siding with the British troops during those crucial battles. Historians agree that the settlers' success at these two battles signaled the turning of the tide of the Revolutionary War—in favor of the Americans.
Martin was born in Caroline County, Virginia, and later lived at Albemarle County and then at Henry County, Virginia, at his plantation, Belmont, on Leatherwood Creek in Martinsville, not far from the plantation of his friend Governor Patrick Henry, Leatherwood Plantation.
General Martin held many positions during his public life. As a very young man he first tried his hand at farming, next he worked for three years as an overseer on the huge plantation of his local Virginia kin, next he was a longhunter, and an explorer on the frontier for friend Patrick Henry, then an early pioneer and builder of Martin's Station in the "wild west," a surveyor of the KY/NC and TN/VA borders, an Indian agent/Indian fighter for Patrick Henry, a member at peace treaties with the Indians, and along with Dr. Thomas Walker, Joseph Martin named the Cumberland region and the Cumberland River, he served as a member of the legislatures of Virginia, Georgia, and North Carolina, he was lifelong friends with Gen. Thomas Sumter, he was also friends and brothers-in-law with Col. Benjamin Cleveland (both married Graves sisters), he was unsuccessfully nominated by Patrick Henry to the position of the first governor of the Southwest Territory, was the holder of some 80,000 acres across the Southeastern U.S. at one point. The city of Martinsville, Virginia, was named in his honor during his lifetime.
