The Second Battle of Panipat was fought was fought on November 5, 1556 between the forces led by Hemu (the general and chief minister of Adil Shah Suri) and the forces of the of the Mughal emperor, Akbar.
After the demise of Babur(founder of Mughal empire), Humayun succeeded the throne of Delhi. However after the Battle of Kannauj on 17 May 1540 , Sher Khan(Sher shah Suri) became the master of Agra and Delhi. Mughal Empire was put to an end for a while and Humayun lived in exile for the next 15 years and Sher Khan founded the Suri Dynasty. After that Islam Shah Suri ascended the throne of Suri dynasty after the death of Sher Shah Suri in 1545 at Kalinjar.
Islam Shah Suri was a bigot ruler, but died in 1554. With the death of these two , the Suri Empire was caught up in a succession battle. Humayun used this perfect opportunity for the Mughals to march back to India and regain the lost power at Delhi in 1540. Humayun with Bairam Khan, commander-in-chief of the Mughal army fought the Battle of Sirhind against Sikandar Shah Suri in 1555 and became victorious.

But after a short period of time, Adil Shah Suri maternal uncle of Firoz shah murdered him and ascended the throne of Suri Empire. He appointed Hemu (commander in chief of the Suri forces) as his Chief Minister. Most of the affairs related to the state were left to Hemu as Adil Shah Suri was interested in luxury and pleasure and trust his work.
After that Humayun died on 27 January 1556 and succeeded by Akbar. Bairam Khan was appointed reagent over the young king Akbar. When Humayun died Tardi Beg Khan was the governor of Delhi. Humayun’s death gives a great opportunity for Suri dynasty to defeat Mughals and regain the lost empire.
