Nur-ud-din Muhammad Salim took the throne name Jahangir. His reign was characterized by relative stability and a great flourishing of Mughal painting. He was an avid naturalist and wrote his memoirs, the Tuzuk-i-Jahangiri, which records his observations on flora and fauna.

Abul Fazl was one of Akbar's 'Nine Gems' and his official court historian. The Akbarnama provides a detailed history of Akbar's reign, while the Ain-i-Akbari focuses on the administration, statistical data, and cultural life of the empire, serving as a primary source for historians.

Raja Todar Mal, the Finance Minister, introduced the Dahshala system based on a 10-year average of crop yields and prices. This data-driven approach allowed for a predictable revenue stream and reduced the arbitrary nature of tax collection, providing stability for the agrarian economy.

Din-i-Ilahi (Divine Faith) was a syncretic religious movement proposed by Akbar that combined elements of Islam, Hinduism, Zoroastrianism, and Christianity. It aimed to unify his diverse subjects under a shared ethical code and loyalty to the emperor, though it gained very few followers outside his immediate circle.

Akbar developed the Mansabdari system to organize the bureaucracy and military. Each official (Mansabdar) held a rank (Zat) determining their status and salary, and a rank (Sawar) indicating the number of cavalrymen they were required to maintain, ensuring a centralized control over regional elites.

Akbar initiated the policy of Sulh-i-Kul to manage the religious and cultural diversity of his empire. This policy emphasized religious tolerance, equal rights for all subjects regardless of faith, and the removal of discriminatory taxes like the Jizya, helping to integrate the Rajput nobility into the Mughal system.

Bairam Khan was a loyal general of Humayun who served as the regent for Akbar from 1556 to 1560. He played a crucial role in consolidating Mughal power and winning the Second Battle of Panipat, though he was later dismissed by Akbar as the emperor sought to rule independently.

The Second Battle of Panipat was fought between the forces of the young Akbar, led by his regent Bairam Khan, and Hemu, the Hindu general of the Sur dynasty. The Mughal victory ensured the survival of the empire and established Akbar as the dominant power in North India.

Sher Shah Suri, an Afghan leader, defeated Humayun at the Battles of Chausa (1539) and Kannauj (1540). During his five-year rule, he introduced significant administrative and land revenue reforms, including the 'Rupiya' currency and the Grand Trunk Road, which later served as a blueprint for Mughal administration.

Humayun, the second Mughal emperor, faced significant challenges from regional rulers, most notably Sher Shah Suri. After losing his empire in 1540, he spent 15 years in exile at the Safavid court in Persia before successfully reclaiming his throne in 1555 shortly before his accidental death.
