Humayun ascended the throne of Delhi on December 30, 1530, just days after his father Babur’s death. His reign, however, was fraught with challenges, particularly from his brothers and rivals like Kamran Mirza, who aspired to control parts of the empire. Kamran, his half-brother, became the governor of Kabul and Lahore and was one of Humayun’s most dangerous adversaries.
Despite facing internal challenges, Humayun’s first military expedition was against Sultan Mahmud Lodi in 1532, whose ambition to recover the Afghan throne still threatened the Mughal Empire. Humayun’s victory in the Battle of Dadrah (1532) solidified his position in the east. However, this victory was short-lived, as he soon had to contend with Bahadur Shah, the powerful ruler of Gujarat.
Sher Shah Suri (1472–1545)
Sher Shah Suri, born as Farid Khan in 1472 at Bajwara, Hoshiarpur, emerged as Humayun’s most formidable adversary. After being neglected by his father, Hasan Khan, Farid Khan moved to Jaunpur, where he learned Persian and Arabic. It was in Jaunpur that he caught the attention of Jamal Khan, the governor of the region. Afterward, he joined the service of Bahar Khan Lohani, the ruler of Bihar, in 1522. Here, he earned the title of Sher Khan after killing a tiger.
In 1527, Sher Khan briefly served under Babur after Bahar Khan’s jealousy-driven nobles ousted him. However, by 1528, he left Mughal service to resume his career in Bihar. Following Bahar Khan’s death, Sher Khan became the de facto ruler of Bihar under the tutelage of Bahar Khan’s widow, Dadu Bibi, who appointed him deputy governor. After her death in 1529, Sher Khan consolidated power.
Humayun’s Campaigns against Sher Shah
In 1531, Humayun marched against Sher Khan, but the latter evaded conflict through timely submission. However, by 1537, Sher Khan had already gained control over Bihar and Chunar, causing alarm for Humayun. Despite being advised by Yusuf Khalil to focus on the conquest of Gaur first, Humayun undertook the Siege of Chunar. Realizing the futility, Humayun sought peace with Sher Khan and turned his attention to Gaur, which Sher Khan allowed him to capture.
While Humayun celebrated his success in Gaur, Sher Khan rapidly expanded his control between Delhi and Bihar. In June 1539, Sher Khan decisively defeated Humayun in the Battle of Chausa. After this victory, Sher Khan assumed the title of Sher Shah Suri. Humayun suffered another major defeat in the Battle of Qanauj (May 1540) at the hands of Sher Shah, costing him his throne and sending him into exile.
Humayun’s Exile and Return
After his defeat, Humayun was abandoned by Kamran, who refused to provide military support. Humayun sought refuge with Rana Prasad of Umerkot, where Akbar was born to Hamida Banu Begum on 23 November 1542. Eventually, Humayun fled to Persia, converting to Shia Islam to gain the favor of Shah Tahmasp I. With Persian support, Humayun reclaimed Kabul and defeated his rebellious brother Kamran, whom he later blinded.
Humayun’s fortunes changed when Sher Shah’s son, Islam Shah died in 1554 and Firuz, the son of Islam Shah, was killed by his uncle, Muhammad Adil Shah. Taking advantage of the internal strife, Humayun re-entered India, capturing Lahore in 1555 and reclaiming his capital, Delhi, by July 1555. However, his reign was cut short when he died on January 24, 1556, after falling from a staircase.
Sher Shah Suri’s Reign (1540–1545)
After defeating Humayun, Sher Shah became the undisputed ruler of northern India. His administrative reforms and military strategies set the foundation for Mughal governance, and he is often regarded as the forerunner of Akbar.
Sher Shah’s administration divided his empire into 47 sarkars (Divisions), each headed by a Shiqdar (military head) and a Munsif (judicial head). He introduced a system of land revenue collection (1/3rd of produce) based on detailed surveys and fixed rates per unit of land. His currency reforms included the introduction of a silver Tanka weighing 178 grains, which became the standard for the subcontinent for centuries. He also issued gold coins and a copper coin for small transactions.
Sher Shah is credited with implementing Alauddin Khilji’s military reforms, such as transferring officers every two to three years to prevent the accumulation of local power. He also introduced the concept of local police responsibility, where local chiefs were held accountable for crimes in their areas, ensuring effective law enforcement.
Sher Shah’s Legacy
Sher Shah is perhaps best remembered for his infrastructural achievements, such as building the Grand Trunk Road, which stretched from Sonargaon in Bengal to Rohtas in Punjab. He built several forts, including Rohtas Fort (near present-day Jhelum in Pakistan), with 50,000 troops to control the Ghakkars. Sher Shah also built Purana Qila in Delhi on the banks of the Yamuna, as well as his grand mausoleum in Sasaram, completed in 1545.
Sher Shah’s reign ended with his accidental death during the Siege of Kalinjar on May 22, 1545, due to the explosion of gunpowder. He was succeeded by his son, Islam Shah (Jalal Khan), whose reign was marked by internal conflicts.
Humayun’s Return and Final Victory
Taking advantage of the instability following Sher Shah’s death, Humayun returned to India with Persian support. By 1555, he had recaptured Lahore and Delhi. Despite his eventual success, his return to power was short-lived, as he died just six months later on January 24, 1556, leaving his empire to his son Akbar.
