Nawab Sayyid Hassan Ali Khan Barha (1666 – 12 October 1722), also known as Qutub-ul-Mulk, Nawab Sayyid Mian II, Abdullah Khan II, was one of the Sayyid Brothers, and a key figure in the Mughal Empire under Farrukhsiyar.
He was the eldest son of the Nawab of Ajmer, Sayyid Mian Abdullah Khan I and later inherited his father's titles as well as the name Abdullah Khan but was also frequently referred to as Qutb al mulk, "Pivot of the Realm". Deposing emperors at their own will, both Abdullah Khan and his brother Hussain Ali Khan become the most powerful figures in early 18th century Mughal court.
Ancestry
Abdullah Khan was a member of the Barha Dynasty. The meaning of the name Barha is uncertain. While some contend that it comes from the word, "bahir", meaning "outsider" referring to the preference of members of the Barha dynasty to live outside Delhi. Others like the Emperor Jahangir, believed that it came from the Hindi word, "barha", meaning "twelve". In reference to the twelve townships that members of the dynasty had received as fiefs from Sultan Shibabdudin of Ghor when they first arrived in India.
The dynasty descends in the male line from the fourth Rashidun Caliph, Ali, through his younger son Hussain who married Shahrbanu, herself a daughter of the Sassanian Emperor of Persia, Yazdegard III. Due to Ali's status as an Adnanite, the dynasty can trace its ancestry to Abraham through his eldest son Ishmael.
In Arabia, Abdullah Khan's ancestors took part in many rebellions against the authority of the Abbasid Caliphate. One ancestor, Isa bin Zayd, revolted against the Caliph Al Mahdi and was consequently poisoned by that caliph at the age of 45. Subsequently, the dynasty were heavily persecuted by the Abbasid government, and eventually the founder of the Barha dynasty, Abul Farah Al Wasiti, fled from Madina to Wasit and from there he fled to the Ghaznavid Empire. His four sons entered into the military service of Sultan Muhammad of Ghor and received twelve fiefdoms in Punjab, then a part of the Ghor Empire, as reward for their service. Thus the dynasty became quickly established as Nobles of the Sword in ancient India, a status they held under several different empires. They held a particularly high status under the Sultanate of Delhi. When the Chief of the Barha, who was also the Diwan of the empire, was granted the fiefdom of Saharanpur due to his relation with the imperial family. They also enjoyed particularly prominent positions under the reign of the Sur, eventually defecting during the last days in the reign of Sikander Sur of the Sur Empire, to the Emperor Akbar of the Mughal Empire in the course of the siege of Mankot.
Barha claim of Sayyid lineage was not accepted by their contemporaries. Emperor Jehangir remarked that "some people make remarks about their lineage, but their bravery is a convincing proof of their being Sayyids." They were said to be descendants of Punjabi farmers who migrated to Muzaffarnagar.
The Barha dynasty maintains the unique status of having been the only dynasty to participate in all three Battles of Panipat, seminal battles which shaped Indian History. Under the Lodi in the First Battle of Panipat. In the Second Battle of Panipat they gained victory under Bairam Khan, and finally in the Third Battle Of Panipat, the sons of Nawab Ali Muhammad Khan Rohilla fought with Ahmed Shah Abidali against the Maratha.
By the time of the Emperor Aurangzeb, the dynasty was firmly regarded as "Old Nobility" and enjoyed the unique status of holding the premier realms of Ajmer and Dakhin. Realms usually reserved for the rule of members of the Imperial Family.
