Frankfort is a city in Kentucky that serves as the state capital and the county seat of Franklin County. The population was 27,741 at the 2000 census; by population it is the 5th smallest state capital in the United States. Located on the Kentucky River, Frankfort is the principal city of the Frankfort, Kentucky Micropolitan Statistical Area, which includes all of Franklin and Anderson counties. The town of Frankfort likely received its name from an event that took place in 1780s. Native Americans attacked a group of early British-American pioneers from Bryan's Station, who were making salt at a ford in the Kentucky River. After the pioneer Stephen Frank was killed, the settlers called the crossing 'Franks Ford.' This name was later shortened to Frankfort. In 1786 James Wilkinson purchased the 260-acre (1.1 km) tract of land on the north side of the Kentucky River, which developed as downtown Frankfort. He was an early promoter of Frankfort as the state capital.
