If I am writing about a historical figure such as a king (or governor or prince), am I supposed to capitalize the word "king" throughout my discussion of him? For instance: "King James initially made efforts to reform and modernize the country. However, the king later revoked his efforts and returned to his former ways."
Is "the king" correct here, or should it be "the King" and why?
Also, what are these type of words called? Honors? Titles? Epithets?
Thanks!
