Question: Colonel Joesph Hardin, Sr. joined what group that was composed of American frontiersmen from west of the Appalachian Mountains who took part in the American Revolutionary War?

<P0-S0>  While they were present at multiple engagements in the war's southern campaign, they are best known for their role in the American victory at the Battle of Kings Mountain in 1780. <P0-S1>  The term "overmountain" refers to the fact that their settlements were west of, or "over", the Appalachians —the range being the primary geographical boundary dividing the 13 American colonies from the western frontier. <P0-S2>  The Overmountain Men hailed from parts of Virginia, North Carolina, and what is now Tennessee and Kentucky. <P0-S3> The Overmountain Men were American frontiersmen from west of the Appalachian Mountains who took part in the American Revolutionary War. <SEP> <P1-S0> The Indian Reserve is a historical term for the largely uncolonized area in North America acquired by Great Britain from France through the Treaty of Paris (1763) at the end of the Seven Years' War (known as the French and Indian War in the North American theatre), and set aside in the Royal Proclamation of 1763 for use by American Indians, who already inhabited it. <P1-S1>  The British government had contemplated establishing an Indian barrier state in the portion of the reserve west of the Appalachian Mountains, and bounded by the Ohio and Mississippi rivers and the Great Lakes. <P1-S2>  British officials aspired to establish such a state even after the region was assigned to the United States in the Treaty of Paris (1783) ending the American Revolutionary War, but abandoned their efforts in 1814 after losing military control of the region during the War of 1812. <SEP> <P2-S0> Stefan Osmokruhović (German: "Stefan Osmokruch" , ; 1665–died in 1666) was the great judge (de. <P2-S1>  "Grossrichter", sr. "veliki sudac") of the Križevci captainate, who in 1665 led a revolt of the Grenz infantry soldiers in the Varaždin generalate of the Military Frontier against the Austrian officers, after the rights of the frontiersmen had been compromised. <P2-S2>  A Serb, Osmokruhović held secret meetings in the Slavonian Military Frontier, in which many Serbs took part in. <P2-S3>  He was also supported by the judges of Koprivnica and Ivanica, Ilija Romanović and Nikola Vuković, and they all sent letters to the Austrian Leopold I, Holy Roman Emperor about the issues in March 1666. <P2-S4>  Appointed the commander of the Varaždin frontiersmen themselves and named great judge ("Veliki Sudac"), he claimed to answer to no one besides the Austrian Emperor, and sought that the frontiersmen's right to ownership of the land between the Sava and Drava be recognized, among other issues. <P2-S5>  Austrian lieutenant general Fra Johann Josef Herberstein (1639-1689) went to Križevci and demanded that his candidate be accepted as great judge, but the candidate was murdered by the frontiersmen. <P2-S6>  The revolt was finally suppressed in 1666 by Herberstein, and Osmokruhović was sentenced to death. <SEP> <P3-S0>  During the War for Independence, as a member of the militia from Tryon County, Hardin fought the Cherokee allies of Britain along the western frontier and was a signatory of the Tryon Resolves. <P3-S1>  Later in the war, having taken his family over the Appalachian Mountains to the Washington District for safety against the advance of the Red Coats out of South Carolina, Hardin joined the Overmountain Men. <P3-S2>  He saw action at the Battle of Ramsour's Mill and the decisive Battle of Kings Mountain. <P3-S3>  Following the peace with Britain, Hardin was a co-founder and second Speaker of the House for the State of Franklin; and an Assemblyman in the Southwest Territory before its statehood as Tennessee. <P3-S4> Colonel Joseph Hardin, Sr. (April 18, 1734 – July 4, 1801) Hardin was an Assemblyman (Provincial Congressman) for the North Carolina Colony.
