Explanation:

Salar Gunj gate located centrally in Panipat is named after the Hyderabadi Nawab Salar Jung. The gate stands across the main arterial road in Panipat. The Nizam of Hyderabad was a great stooge of British rulers. And all his ministers including the Prime Minister Nawab Salar Jung followed him in respecting the British rule in India. The Nizam took the side of British Government when the first war on independence broke out against the British.

Naawab Salar Jung was so loyal to the British Government that when he came to know about the fact that the freedom fighters were about to attack the residency in Hyderabad, he informed the same to the Government in advance. This helped the residency to prepare in advance and defeat the freedom fighters.
Being happy with the Nawab’s loyalty, the British Government knighted him as Sir and gave him the title of Salar Jung. Officially the Nawab was addressed as Sir Salar Jung and common people referred him as Nawab Sahib.
