Answer 2

Louis the 14th died in 1715. Specifically, 1st September 1715.

He died of senile gangrene. He started experiencing the symptoms on 10th August 1715 but was misdiagnosed by his doctors. The doctor said he was suffering from sciatica, a non life threatening sickness due to old age. 
This misdiagnosis led to his death, because by the time the doctors realized their mistake, the disease has already attack the bones of King Louis causing him to fall into coma before dying.
