King George III, who ruled England during the period of the revolutionary war in the United States, exhibited sporadic periods of “madness” near the end of his life. In retrospect, it appears that he showed symptoms of porphyria, an autosomal dominant disorder of heme metabolism. In addition to “madness”, the symptoms of porphyria, which include a variety of physical ailments (paralysis, high blood pressure agonizing abdominal pain, manic overactivity, skin rash, red urine, delirium and psychosis) that were shown by King George III, are sporadic and variable in severity, can be affected by diet and, currently, can be treated with medication. Of King George’s 16 children, only 2 showed any symptoms of porphyria.
