The Grand Trunk Road is one of South Asia's oldest and longest major roads. For several centuries, it has linked the eastern and western regions of the Indian subcontinent, running from Chittagong, Bangladesh through to Howrah, West Bengal in India, across north India into Peshawar (in present day Pakistan), up to Kabul, Afghanistan. Its former names include Uttarapatha ("the road to north"), Shah Rah-e-Azam ("great road") or Sadak-e-Azam or Badshahi Sadak.
The route spanning the GT road existed during the Mauryan Empire, extending from the mouth of the Ganges to the north-western frontier of the Empire. The modern road was built by Sher Shah Suri, who renovated and extended the ancient route in the 16th century

My favourite Historical Character. Sher Shah Suri, who defeated the lazy Mughal Humayun and chased out towards Sindh and further. And declared himself the Emperor of India.
Sher Shah Suri was the first to introduce a postal system (horsemen relaying dak from obe saraye to another).
He introduced the revenue collection system which was later followed by the British and after them today the system is being followed.
He contained law and order situation which was in a very bad shape during Humayun misrule.
And Sher Sha Suri introduce new currency system and named it as RUPAYAH.
Today Rupee is the name of currency of many countries, apart from India. Pakistan, Nepal, Mauritius etc.
