Grand Trunk Road

Also called: Sadak-e-Azam · Topic: The Mughal Empire: Babur to Aurangzeb · NCERT: Beyond NCERT

Meaning

The Grand Trunk Road (also called Sadak-e-Azam, "the great road") is a very old highway across north India. Sher Shah Suri rebuilt it during his rule (1540–1545), and it ran from Bengal in the east to Peshawar in the north-west. [3]

It matters because Sher Shah turned an old trade route into a working imperial system. He added sarais (rest houses), kos minars (distance pillars) and a horse-rider postal service along it. The Mughals took this network over, and much of the same route is still a major road in South Asia today.

Explanation

Background: why Sher Shah needed a road

• A great road across the north Indian plains is very old. In ancient times the route linking the Gangetic plain to the north-west was known as Uttarapatha (the "northern road"). It was used by traders and armies.
• Sher Shah Suri, an Afghan leader, built up his power first in Bihar and Bengal.
• He beat Humayun at Chausa (26 June 1539) and Kannauj (May 1540). [2]

• He then founded the Sur dynasty and ruled north India from Bengal to the north-west. [2]

• A state that large had to move troops, news and trade goods quickly between its eastern base and its north-western frontier. So Sher Shah rebuilt the old imperial highway. [3]

Main features of Sher Shah's road system

• The main road: the Grand Trunk Road, from Bengal to Peshawar. Older textbooks often name Sonargaon (in Bengal) as its eastern end. [3]
• Two other roads were part of the same network: [3]
• Agra to Jodhpur and Chittor, which linked up with the ports of Gujarat.

• Lahore to Multan.

• Sarais were roadside rest houses where travellers and traders could sleep, eat and change horses. Sher Shah built many of them along these roads. [3]

• Kos minars were tall, round brick pillars. Each one marked a distance of 1 kos (about 3 km), so travellers knew how far they had come. [3]
• Postal service: Sher Shah set up a regular post carried by horse riders along the same roads. [3]

How it worked: one road, many jobs

• The sarais did two jobs at once:
• they were trade stops for merchants;

• they were postal relay points, where riders handed over news and took fresh horses.

• Roads, coins and revenue worked together:

• Merchants on the road used Sher Shah's standard coins, the silver rupiya, the gold mohur and the copper dam. [1]

• Fixed land revenue, with land measured and the peasant's share set in advance, meant regular taxes could be collected and paid for this network. [3]

• Control from the centre: fast riders let the ruler hear quickly about revolts or troubles in far provinces.

What happened next

• Sher Shah died on 22 May 1545, after only about five years of rule. [2] His empire did not last long, but the road system did.
• When Humayun came back (1555) and Akbar won the Second Battle of Panipat (1556), the Mughals took over Sher Shah's roads, sarais and post. [2][5]
• The Mughal dak (postal relay system) ran along this route. Many of the kos minars that still stand were put up by later Mughal rulers.
• In the colonial period the British rebuilt and metalled the road and gave it the English name "Grand Trunk Road".
• Today the route still runs through India, Pakistan and beyond. Its modern successors are national highways.

Time, place and evidence

• Period: the old route is ancient. It was rebuilt under the Sur dynasty by Sher Shah Suri (ruled 1540–1545), then used by the Mughals and later rebuilt by the British. [1][2]
• Region: across north India, from Bengal, through Bihar, the Gangetic plain, Agra/Delhi and Lahore, to Peshawar. [3]
• Key people:
• Sher Shah Suri, who rebuilt the road, the sarais and the postal system. [3]

• Humayun and Akbar, whose empire later used this system. [2][5]

• How we know:

• Standard modern histories of Sher Shah, such as Britannica, describe his roads, sarais, kos minars and post. [3]
• Surviving kos minars and old sarai buildings along the route are physical evidence.
• Mughal-era court histories also record Sher Shah's reforms. The best known is Abbas Khan Sarwani's Tarikh-i-Sher Shahi, written under Akbar.
• Sher Shah's tomb at Sasaram (Bihar), his home region near the road, is protected by the Archaeological Survey of India. [4]

Don't confuse with

• Uttarapatha: the ancient name for the northern trade route, used in Mauryan times and earlier. The Grand Trunk Road is its later version, rebuilt by Sher Shah. "Grand Trunk Road" itself is a later English name.
• Agra–Jodhpur–Chittor road: also built by Sher Shah, but it ran south-west towards the Gujarat ports. It did not run from Bengal to Peshawar. [3]
• Kos minar vs sarai: a kos minar is only a distance-marker pillar (1 kos ≈ 3 km). A sarai is a rest house where people could sleep and change horses. [3]
• Sher Shah's post vs the Mughal dak: Sher Shah started the regular horse-rider post on these roads. [3] The Mughals inherited and extended it. Exam questions usually credit the original system to Sher Shah.

Prelims Hooks

• Grand Trunk Road was rebuilt by Sher Shah Suri (Sur dynasty), running from Bengal to Peshawar. [3]
• Sher Shah's other roads: Agra–Jodhpur–Chittor and Lahore–Multan. [3]
• Kos minar = brick pillar marking 1 kos ≈ 3 km. [3]
• Sher Shah ruled 1540–1545 and died on 22 May 1545. His tomb is at Sasaram, Bihar (ASI-protected). [1][2][4]
• Order of events: Chausa (1539) → Kannauj (1540) → Sher Shah builds the road network → Humayun recovers Delhi (1555) → Panipat II (1556). [2][5]
• Trap: the name "Grand Trunk Road" is British, not Mughal. The road itself is ancient, and Sher Shah (not Akbar) rebuilt it.

Mains Points

• The road as a tool of state-building. Sher Shah's road, sarai and post network, his standard coins and his fixed land revenue formed one connected system. It tied the Bengal–Bihar east to the north-west frontier. The Mughals inherited this "Afghan administrative frame" and made it the base of Akbar's empire. [1][3]
• Continuity across empires. The same corridor was used for over two thousand years: as the ancient Uttarapatha, as Sher Shah's highway with sarais, as the route of the Mughal dak, as the British "Grand Trunk Road", and today as national highways. It is a good example for "continuity and change" answers in GS-I.
• Roads, trade and culture. Sarais and safe roads helped merchants, pilgrims and soldiers move around. They linked markets and helped spread coins, languages and building styles across north India. The road shows that good infrastructure can outlast the dynasty that built it, since Sher Shah's state ended in about five years but his road did not. [2][3]
