Dhu Nuwas
The Axumite Kingdom is recorded once again as controlling part – if not all – of Yemen in the 6th century CE. Around 523 CE, the Jewish king Dhu Nuwas came to power in Yemen and, announcing that he would kill all the Christians, attacked an Aksumite garrison at Zafar, burning the city's churches. He then attacked the Christian stronghold of Najran, slaughtering the Christians who would not convert.
