In 1786 James White built a fort five miles below the junction of the French Broad and Holston Rivers on the
southernmost edge of frontier settlement in present-day East Tennessee. William Blount, governor of the Territory of
the United States South of the River Ohio, selected the site of James White's Fort as the territorial capital in
1791 and gave it the name Knoxville in honor of Revolutionary War hero General Henry Knox (1750-1806), who served as
the first US secretary of war from 1785 to 1794.
