Boonesborough, called the "Capital of the Colony of Transylvania," was setted in April, 1775, by Daniel Boone as the first fortified settlement in Kentucky. Near the fort under the "Divine Elm Tree" in May, 1775, Colonel Richard Henderson held the first legislative assembly of frontier settlers from Harrodsburg, St. Asaph, Boonesborough, and Boiling Springs. In 1778, the Kentucky frontier was saved by two major military victories: settlers withstood the Great Siege of Boonesborough, and George Rogers Clark defeated British and Indians at Kaskaskia and Vincennes. The fort became the first town chartered in Kentucky in October, 1779, by the Virginia Assembly.
