Jovian 

Flavius Jovianus, 363 - 364

Captain of the Imperial Guard under Julian II , Jovian was proclaimed emperor on Julian's death. He concluded the war with the Persians by signing a humiliating peace, by which most of the Roman gains of the previous century were surrendered. On his was back to Constantinople, he suffocated to death when a charcoal-burning brazier was left in his bedchamber. Romans were careless people, and did not take good care of their emperors.
