t seems you can step out your front door without seeing the words “Keep Calm and Carry On” on a t-shirt, coffee mug or poster. Where did this comforting phrase come from and what launched it into the collective consciousness? The line dates back to a propaganda campaign launched by the British government in World War II, the bold white letters on a red background with the crown was designed for the purpose of boosting moral in case of a German invasion. The invasion never happened and almost all of the posters were destroyed and the slogan never distributed among Britain’s war torn masses.
