Mughal emperor of India from 1713-19, was the second son of Azim al-Shan, the third son of Bahadur Shah. Born at Aurangabad in the Deccan on 11 September 1683, he in his tenth year accompanied his father to Agra, and in 1697 to Bengal, when that province was added to his charge. In 1707, when Azim al-Shan was summoned to the court by Aurangzeb, Farrukh-Siyar was nominated his father's deputy there, which post he held until his recall by Azim al-Shan in 1711. When Bahadur Shah died at Lahore on 27 February 1712, Farrukh-Siyar was at Patna, having tarried there since the previous rainy season. Following the defeat and death of his father in the contest at Lahore, Farrukh-Siyar proclaimed himself king at Patna on 6 March 1712. He marched on Delhi, defeating Jahandar Shah, who had succeeded Bahadur Shah, on 10 January 1713, after a hard-fought battle at Samugarh near Agra.

After his accession to the throne of Delhi, Farrukh-Siyar launched the sternest proceedings against Sikhs who had under Banda Singh Bahadur risen in the Punjab. He deputed his best military generals against them. Abd us-Samad Khan was appointed governor of Lahore and was entrusted with the task of quelling Sikh insurrection. According to Akhbdr-i Darbdr-MuAlld, high-ranking military generals such as Bakhshi ul-Mulk Muhammad Khan Bahadur, Ghazi ud-Din Khan Bahadur, Mahabat Khan Bahadur and Hamid ud-Din Khan Bahadur moved against the Sikhs at the head of their forces.

Chopped heads of the victims were often sent to the emperor by the commanders to win his pleasure. Sikhs' main column under Banda Singh Bahadur was subjected to a most stringent siege at the village of Gurdas-Nangal, about 6 km from Gurdaspur. For eight long months, the garrison resisted the siege under gruesome conditions. The royal armies at last broke through and captured Banda Singh and his famishing companions on 7 December 1715. After being paraded in the streets of Lahore, they were taken to Delhi where they arrived on 27 February 1716. Besides 740 prisoners in heavy chains, the cavalcade to imperial capital comprised seven hundred cartloads of the heads of Sikhs with another 2,000 stuck upon pikes. By FarrukhSiyar's order, Banda SiAgh and some two dozen leading Sikhs were imprisoned in the Fort, while the remaining 694 were made over to the kotwal, Sarbarah Khan, to be executed in the Kotwah Chabutra at the rate of a hundred a day. Then Banda SiAgh Bahadur and his remaining companions were taken to the tomb of Khwaja Qutb ud-Din Bakhtiyar Kaki, near the Qutb Minar. There he was offered the choice between Islam and death. Upon his refusal to renounce his faith, his four-year son, Ajai Singh, was hacked to pieces before his eyes. Banda Singh himself was subjected to the harshest torments. His eyes were pulled out and hands and feet chopped off. His flesh was torn with red-hot pincers and finally his body was cut up limb by limb. This happened on 9 June 1716.

According to George Forster, A Journey from Bengal to Fngland, an edict was issued by Farrukh-Siyar after the execution of Banda Sirigh directing that
"every Sicque falling into the hands of his officers should, on a refusal of embracing the Mahometan faith, be put to the sword. A valuable reward was also given by the emperor for the head of every Sicque; and such was the keen spirit that animated the persecution, such the success of the exertions, that the name of a Sicque no longer existed in the Mughul dominion. Those who still adhered to the tenets of Nanock, either fled into the mountains at the head of the Punjab, or cut off their hair, and exteriorly renounced the profession of their religion."

Farrukh-Siyar was deposed and blinded by his own men with needles pressed into his eyes on 28 February 1819 and choked to death on the night between 27 and 28 April.
