Why is the capitol of Oklahoma called the Oklahoma City?

The capitol of Oklahoma is not the "The Oklahoma City" but rather simply "Oklahoma City." While there are many possible answers to this question the simplest one could be due to Oklahoma's Land Run. Literally entire cities sprang up over night, and it was often difficult for residents of a particular town to decide spontaneously on a name. Oklahoma City was probably just the easiest thing to name the city. After all, it was a city in Oklahoma.
