Once upon a time there were people living in the area currently known as Nashville. Those people didn’t really care for country music since they were busy growing corn and fighting off saber tooth tigers. Then other people came along, and then other people, and blam! Before you could say “country twang” there was a thriving metropolis.
They named the thriving metropolis (and by “thriving metropolis” I mean the small fort) Fort Nashborough in honor of the war hero General Francis Nash. In 1784, the community decided to change its name to Nashville because that sounded more likely to attract country singers in the 20th century.
Tennessee became the 16th state in 1796 and Nashville became the capitol in 1843.
