Dhu Nuwas
Around 455 CE, the last Himyarite King is born, "Zur'ah Yusuf Ibn Tuban As'ad Abu Kaleb Dhu Nuwas" or Dhu Nuwas. He died in 510. His zeal for Judaism brought about his fall. Having heard of the persecutions of Jews by Byzantine emperors, Dhu Nuwas retaliated by putting to death some Byzantine merchants who were traveling on business through Himyara. He didn't simply kill them with hanging—he burned them in large pits—earning him the title "King of the burning pit".
