1781 CE
The King of Germany forbids coffee roasting except in official government establishments

Frederick the Great forbade coffee roasting in 1781 (except in official government establishments). Four years earlier he had issued a manifesto that expressed his discontent with how popular coffee had become in Germany (he argued that his people should drink beer as him and his ancestors had been brought up on it). As a result of the ban, poor people were forced to replace coffee with coffee substitutes such as chicory root or roast beans clandestinely.
