Imru al-Qays I ibn Amr
Imru al-Qays ibn Amr ibn Adi, commonly known as Imru al-Qays I, was the second Lakhmid king. His mother was Maria bint 'Amr, the sister of Ka'b al-Azdi.
Al-Tabari states that "he ruled for the Persians in all the land of the Arabs in Iraq, Hejaz and Mesopotamia". Imru al-Qays is called in his epitaph inscription: "The king of all Arabs who owned the crown," while the same title was the title given to the kings of Hatra. The same inscription mentions that Imru al-Qays reached as far as Najran and besieged it from the king, Shammar Yahri'sh. Some scholars have identified "Imru al-Qays ibn Amr" in some South Arabian inscriptions with that one. In those same inscriptions his name is mentioned along with Shammar Yahri'sh, the Himyarite king.
