Abdullah Khan. With Abdullah Khan commanding the vanguard, Farrukhsiyar began the attack. After a night-long artillery fight, Aazuddin and Khwaja Ahsan Khan fled and the camp fell to Farrukhsiyar. On 10 January 1713, Farrukhsiyar and Jahandar Shah's forces met at Samugarh, east of Agra in present-day Uttar Pradesh. Jahandar Shah was defeated and imprisoned, and the following day Farrukhsiyar proclaimed himself the Mughal emperor. On 12 February, Farrukhsiyar marched to the Mughal capital of Delhi, capturing the Red Fort and the citadel. Jahandar Shah's head, mounted on a bamboo rod, was carried by an executioner on an elephant and his body was carried by another elephant. Reign Hostility with the Sayyid brothers Farrukhsiyar defeated Jahandar Shah with the aid of the Sayyid brothers, and one of the brothers, Abdullah Khan, wanted the post of wazir (prime minister).

Hussain Ali Khan felt it necessary to act in their interests "without regard to the plans of the new sovereign". Farrukhsiyar could not confront them, as the Sayyid Brothers maintained control of the strongest part of the army, and thus the latter became de-facto rulers of the empire. Campaign against Ajit Singh Maharaja Ajit Singh captured Ajmer with the support of the Marwari nobles and expelled Mughal diplomats from his state. Farrukhsiyar sent Hussain Ali Khan to subjugate him. However, the anti-Sayyid brothers faction in the Mughal emperor's court compelled him to send secret letters to Ajit Singh assuring him of rewards if he defeated Hussain Ali Khan. Hussain left Delhi for
