While the Battle of Sirhind (1555) allowed Humayun to retake Delhi, the Second Battle of Panipat (1556) against Hemu definitively ended the Afghan challenge.

Sher Shah introduced 'Patta' (title deed given to the peasant) and 'Qabuliyat' (deed of agreement/acceptance signed by the peasant).

Sher Shah built the Qila-i-Kuhna mosque within the Purana Qila (Old Fort) complex in Delhi.

Sher Shah is considered the forerunner of Akbar because Akbar adopted and refined many of Sher Shah's administrative, revenue, and military policies.

His second son, Jalal Khan, succeeded him and took the title of Islam Shah Suri.

Abbas Khan Sarwani wrote 'Tarikh-i-Sher Shahi' at the command of Akbar, providing a detailed history of Sher Shah's reign.

The copper coin introduced by Sher Shah was called 'Dam'. 40 Dams were equal to 1 Rupiya.

The massive Rohtas Fort was built to suppress the Gakkhar tribes of the Potohar region, who were loyal to the Mughals.

Hemu was the wazir and general of Adil Shah Suri. He captured Delhi briefly and took the title 'Vikramaditya' before falling at the Second Battle of Panipat.

Sher Shah introduced the Zabti system, where land was measured and revenue was fixed based on the measurement and the quality of land. This was later adopted and refined by Akbar.
