LARGO OF SERDICA, ANNO 2016
In 313, a PR trick helped Constantine to become the sole ruler of the Roman Empire, whence he would go down in history as "The Great." Before a crucial battle he claimed that he had a dream in which he was advised to paint the initials of Jesus Christ, a theretofore forbidden god, on the shields of his soldiers with the promise that this would bring him victory. He did just that. He won, decriminalised Christianity, became a saint, and so on and so forth.
