Throughout history, some national leaders can definitely be said to have thought highly of themselves, but most left it to their adoring public to call things after them. Not so the Roman Emperor Commodus, who in the ‘Golden Age of Commodus’ turned practically everything into a variation of his name. Such as having his realm become Commodiana, its capital Colonia Commodiana, the senate the Commodianus and the army the Commodiani. Even the calendar was revamped, with the months all acquiring names honouring the megalomaniac. But these changes only lasted until people who thought much less highly of him did him in in 192 AD.
