Was King George III truly mad, or did history just prefer a convenient diagnosis?
In short: For decades, the erratic behavior of King George III was blamed on a rare genetic disorder called porphyria. This diagnosis, popularized by mid-1960s psychiatrists, became historical gospel. Yet, modern researchers now argue the evidence is flimsy, suggesting the monarch likely suffered from severe mental illness instead of a metabolic disease.
The narrative that George III suffered from acute porphyria was famously advanced in the 1960s by psychiatrists Ida Macalpine and Richard Hunter. After reviewing over 100 volumes of the king's medical records, they concluded his symptoms—including abdominal pain, seizures, and blue-tinted urine—pointed to a metabolic condition. This theory gained immense traction, eventually appearing in popular culture through Alan Bennett’s 1991 play and the 1995 film, The Madness of King George.
However, the porphyria diagnosis has faced significant scrutiny. Critics, including Dr. Timothy Peters, argue that Macalpine and Hunter were selective in their interpretation of historical records. Furthermore, a 2005 hair analysis revealed high levels of arsenic in the king's system, likely from medicinal treatments that may have exacerbated his condition. Some experts now suggest that diagnosing a king with a physical, metabolic ailment was simply more palatable to the public than acknowledging a mental health crisis in an era when such topics were largely taboo.
Recent research from St George's, University of London, offers a different perspective. By analyzing the king's handwritten letters, researchers Peter Garrard and Vassiliki Rentoumi observed that his sentences became significantly longer and more complex during episodes of illness. This pattern of nonstop, creative speech is consistent with the manic phase of bipolar disorder, a conclusion that aligns with descriptions provided by 18th-century witnesses. While the king’s erratic behavior triggered constitutional crises—most notably the Regency Crisis of 1788—the true nature of his suffering remains a subject of intense historical debate.
