Azd

The Azd (Arabic: أَزْد), or Al-Azd (Arabic: ٱلْأَزْد), is an ancient Arabian tribe. The lands of Azd occupied an area west of Bisha and Al Bahah in what is today Saudi Arabia.
Pre-Islamic inscriptions, specifically Sabaic inscriptions from Sha'r Awtar's reign (210-230 CE), indicate that the land of Azd extended west of Bīsha, in the south-western heights of Saudi Arabia, stretching between the regions of al-Bāḥa and ʿAsīr.
Al-Azd's land during the eve of Islam was comparable to that of the contemporary Azd Sarāt, stretching from Bīsha to the Tihāma shores, the southern limit being approximately al-Nimāṣ and the northern one the modern town of al-Bāḥa.
In ancient times, Al Azd inhabited modern day provinces of 'Asir Province and Al-Bahah Province in modern-day Saudi Arabia, bordering Sabaeans in modern-day Yemen. the Azd tribe have always inhabited the Sarawat Mountains in Hejaz; Azd Shanū’ah (Zahran & Ghamid) Bariq inhabited Tihamah; and Azd Mazin (Al Ansar & Ghassanids) inhabited two different regions, where the Ansaris settled in Medina, Hejaz, while the Ghassanids settled in the far north of the Arabian Peninsula.
According to traditional medieval Yemeni folklore, the Azd tribal group originally lived in Yemen, until the collapse of the Ma'rib Dam when they began emigrating to other parts of the Arabian Peninsula due to the living conditions becoming unfavourable. This large movement out of Yemen has been dated to the late 3rd century CE.
A genetic haplogroup often associated with Azdite tribes, J-BY74, has been indicated to have originated in Northern Arabia or the Levant.
In the 3rd century C.E., the Azd branched into four sub-branches, each led by one of the sons of Muzayqiya.
Imran bin Amr and the bulk of the tribe went to Oman, where they established the Azdi presence in Eastern Arabia. Later they invaded Karaman and Shiraz in Southern Persia, and these came to be known as "Azd Daba". Another branch headed west back to Yemen, and a group went further west all the way to Tihamah on the Red Sea. This group was to become known as "Azd Uman" after the emergence of Islam.
Jafna bin Amr and his family headed for Syria, where he settled and initiated the kingdom of the Ghassanids. They were so named after a spring of water where they stopped on their way to Syria. This branch was to produce:
Thalabah bin Amr left his tribe for the Hijaz, and dwelt between Thalabiyah and Dhi Qar. When he gained strength, he headed for Yathrib, where he stayed. Of his seed are the Aws and Khazraj, sons of Haritha bin Thalabah. These were to be the Muslim Ansar and were to produce the last Arab dynasty in Spain (the Nasrids).
Haritha bin Amr led a branch of the Azd Qahtani tribes. He wandered with his tribe in the Hijaz until they came to the Tihamah. He had three sons Adi, Afsa and Lahi. Adiy was the father of Bariq, Lahi the father of Khuza'a and Afsa, the father of Aslam.
The Zahran tribe is an ancient Arabian offshoot of the Azdi tribe.
The Azd 'Uman were the dominant Arab tribe in the eastern realms of the Caliphate and were the driving force in the conquest of Fars, Makran and Sindh. They were the chief merchant group of Oman and Al-Ubulla, who organized a trading diaspora with settlements of Persianized Arabians on the coasts of Kirman and Makran, extending into Sindh since the days of Ardashir. They were strongly involved in the western trade with India, and with the expansion of the Muslim conquests, they began to consolidate their commercial and political authority on the eastern frontier. During the early years of the Muslim conquests, the Azdi ports of Bahrain and Oman were staging grounds for Muslim naval fleets headed to Fars (Persia) and Hind (India). From 637 C.E., the conquests of Fars and Makran were dominated by the Azdi and allied tribes from Oman. Between 665 and 683 C.E., the Azdi 'Uman became especially prominent due in Basra on account of favors from Ziyad ibn Abihi, the Governor of Mu'awiya I, and his son Ubaidullah. When a member of their tribe Abu Said Al- Muhallab ibn Abi Sufra became governor their influence and wealth increased as he extended Muslim conquests to Makran and Sindh, where so many other Azdi were settled. After his death in 702, though, they lost their grip on power with the rise of Al-Hajjaj ibn Yusuf as governor of Iraq. Al-Hajjaj pursued a systematic policy of breaking Umayyad power, as a result of which the Azd also suffered. With the death of Hajjaj and under Sulayman ibn Abd al-Malik as Caliph, their fortunes reversed once again, with the appointment of Yazid ibn al-Muhallab.
