The Last Powerful Mughal Ruler
The last powerful Mughal ruler was Aurangzeb, who reigned from 1658 to 1707. His rule marked the zenith of the Mughal Empire, but also the beginning of its decline.
Key Characteristics of Aurangzeb's Rule
- Expansion of Empire: Aurangzeb expanded the Mughal Empire to its greatest territorial extent, conquering regions in the Deccan and South India.
- Religious Policies: He is known for his orthodox Islamic policies, which included the re-imposition of the jizya (a tax on non-Muslims) and the destruction of temples, leading to resentment among Hindu subjects.
- Military Campaigns: Aurangzeb engaged in prolonged military campaigns, especially against the Marathas, which drained the empire's resources and stretched its military thin.
Decline of the Mughal Empire
- Administrative Challenges: Aurangzeb's focus on military conquests led to neglect in administration and governance, resulting in corruption and inefficiency.
- Rise of Regional Powers: The weakening of central authority allowed regional powers like the Marathas, Sikhs, and others to assert their independence, further fragmenting the empire.
Legacy
- Cultural Impact: Despite his policies, Aurangzeb's era saw significant cultural developments, including contributions to art and architecture, although they were overshadowed by his repressive measures.
- End of an Era: After his death in 1707, the Mughal Empire continued to decline, ultimately leading to British colonial rule in India.
In summary, Aurangzeb's reign was marked by both expansion and internal strife, laying the groundwork for the eventual disintegration of the Mughal Empire.
