Capital and largest city
The capital of Oklahoma is Oklahoma City — which is also the largest city in the state. About 17 of the 50 US state capitals also hold the title of largest city; Oklahoma is one of them.
The historical reason for these mismatches dates to the late 18th and 19th centuries. When state founders chose capitals, they often deliberately picked smaller, more centrally located towns to avoid concentrating political and commercial power in the same place. They worried that a capital in a major port or commercial city would be too vulnerable to mob influence (a real concern at the time) and would skew political decisions toward commercial interests.
