Imru al-Qays I ibn Amr

Imru al-Qays ibn Amr ibn Adi (Arabic: امرؤ القيس بن عمرو بن عدي, romanized: Imruʾ al-Qays ibn ʿAmr ibn ʿAdī), 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 (king of all Arabs) 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.
