Colonel ( or ) is a military rank of a commissioned officer, with the corresponding ranks existing in nearly every country in the world. The rank of Colonel is one of the oldest in existence, dating as far back as the time of the Roman Empire.

The title colonel is conferred as an honor by some southern states in the United States of America. The origins of the southern colonelcy can be traced back to colonial and antebellum times when plantation masters were given the title for financing the local militia without actual expectations of command. This practice can actually be traced back to the English Renaissance when a colonelcy was purchased by a lord or prominent gentleman but the actual command would fall to a lieutenant colonel, who would deputise for the proprietor.
