City (pop., 2000: 711,470), capital of Ohio, U.S. Located at the junction of the Scioto and Olentangy rivers, the city was planned in 1812 as a political centre and sited opposite the original 1797 settlement of Franklinton; the state government moved to the city in 1816.
The arrival of roads, canals, and rail in the mid 19th century led to significant growth, and by 1900 Columbus had emerged as an important transportation and commercial centre. It is Ohio's largest city, and its economy is supported by industry, governmental agencies, and numerous educational and research institutions, including the Ohio State University .
