After brushing aside light Maratha resistance, he reached Delhi on 28 January and soon forced the Mughal emperor Alamgir II to submit to him.

It marked a significant blow to the already weakened Mughal Empire; months later, the Bengal Subah was subjugated by the British in the Battle of Plassey.

Opening peace negotiations, Ahmad Shah demanded the revenues of Chahar Mahal, Gujrat, Aurangabad, Pasrur, and Sialkot.

[9][12] He initially demanded the revenues of Chahar Mahal, and Moin-ul-Mulk, unable to pay the full sum, gave a tribute of 900,000 rupees and promised more if the Afghans withdrew.

[16][17] Due to the tyrannies of Imad ul-Mulk, other nobles such as Najib ud-Daula, a chief of Rohilkand, and the new Mughal emperor Alamgir II, also requested Ahmad Shah to invade.

Ahmad Shah accepted the invitations and began his fourth invasion in November 1756, leaving Peshawar on the 15th, and crossing Attock on the 26th with an army of 80,000 men.

[4] Ahmad Shah garnered tribute from the city before continuing his march, crossing the Sutlej on 10 January at Ludhiana, while the advance guard under his general, Jahan Khan, had seized Sirhind, Karnal, and Panipat.

[19][20] The Marathas, who had signed a treaty to protect the Mughals from foreign invasions in 1752,[21] assembled a contingent of 3,400 men under Antaji Mankeshwar, who skirmished with the Afghans at Narela.

Jahan Khan advanced to Luni and besieged Shahdara following this on 17 January, and the Jama Masjid in Delhi saw Ahmad Shah's name read in the Khutbah as a sign of sovereignty.

[24][25] Meeting with Alamgir at the Fatehpuri Mosque, Ahmad Shah led a grand entry into Delhi, which was marked with a gun salute.

On the 29th, bazaars were sacked and Jahan Khan's soldiers extracted tribute from Feroz Shah Kotla, a large fortress in Delhi.

Unable to produce the required wealth, Intizam admitted that his father had buried a fortune and revealed that an elderly woman, Sholapuri Begum, knew its location.

Mere months later, the army of the Bengal Subah, weakened due to the Afghan invasion, were utterly defeated at the Battle of Plassey, beginning the rise of British power in India.
