A leper in purple: the coronation of Baldwin IV of Jerusalem

Baldwin IV, the leper king of Jerusalem, was one of history's more startling monarchs. His coronation in 1174 has been interpreted as anomalous or, alternatively, as evidence of unique cultural and political trends within the Latin Kingdom of Jerusalem. Inherent in all these evaluations, however, is the unquestioned acceptance that Baldwin was known to be leprous at the time of his coronation. This is an assumption that is supported by neither medical understandings of the disease, nor by a consideration of the evidence that survives from the period. Though clearly suffering from advanced leprosy at the time of his death, there is nothing to suggest that Baldwin's disease could have been diagnosed prior to his taking the throne and so there is no need to consider his coronation as anything other than a conventional one.
