The reign of the sixth Mughal Emperor, Muhi-ud-Din Muhammad Aurangzeb (r. 1658–1707 CE), represents both the maximum territorial expansion and the structural fragmentation of the Mughal Empire. By the mid-1670s, Aurangzeb shifted his attention southward toward the Deccan plateau, driven by three primary strategic motives: suppressing the rising power of the Maratha Kingdom, annexing the wealthy Shia Sultanates of Bijapur and Golconda, and enforcing central imperial authority over South India.
In 1681 CE, Aurangzeb relocated the entire imperial court and army southward, never to return to Northern India. What was intended as a quick campaign turned into a 26-year war of attrition known as the “Deccan Ulcer”—a draining conflict that overextended Mughal resources and accelerated the empire’s decline.
1. Conquest of the Deccan Sultanates (1685–1687 CE)
Aurangzeb sought to absorb the independent Deccan Sultanates, accusing them of failing to pay tribute, protecting Maratha raiders, and supporting Shia practices.

The Annexations and Strategic Fallout
-
Siege of Bijapur (1685–1686 CE): After fifteen months of siege operations led directly by Aurangzeb, the Adil Shahi capital surrendered due to food shortages and intense artillery bombardment.
-
Siege of Golconda (1687 CE): The fortified citadel of Golconda resisted Mughal assault for eight months. The fort fell only after Mughal agents bribed a gatekeeper, granting imperial forces access to the interior.
While these victories brought the Mughal Empire to its largest territorial extent—spanning from Kabul to Chittagong and down to Tamil Nadu—annexing Bijapur and Golconda eliminated the buffer states that had helped contain Maratha expansion.
2. The Maratha Challenge and Guerilla Warfare (Ganimi Kava)
The rise of Chhatrapati Shivaji Maharaj introduced a style of mobile warfare that challenged traditional Mughal military doctrine.

| MUGHAL IMPERIAL ARMY |
| Primary Force: Massive, slow-moving heavy cavalry, siege trains, |
| and encampments. Vulnerable to supply-line disruption. |
|-------------------------------------------------------------------|
| MARATHA FORCES |
| Primary Force: Fast, light cavalry operating via *Ganimi Kava* |
| (guerilla warfare). Avoided pitched battles; cut supply lines. |
+-------------------------------------------------------------------+
The Unending Resistance
Following the capture and execution of Shivaji’s son, Sambhaji Maharaj, in 1689 CE, Aurangzeb expected Maratha resistance to collapse. Instead, leadership shifted to Rajaram and later to Regent Tarabai Mohite, who decentralized the Maratha command structure.
Local commanders operated independently across the Western Ghats, ambushing Mughal supply convoys, recapturing hilltop fortresses (Forts of Sahyadri), and levying tax demands (Chauth and Sardeshmukhi) within Mughal-held territory.
3. Economic Crisis: The Jagirdari Breakdown and Administrative Drift
The long military campaigns in the Deccan created severe structural strain across the imperial administration.
| Area of Impact | Nature of Structural Breakdown | Historical Consequence |
| Jagirdari Crisis | Expansion brought hundreds of new nobles into the Mansabdari system, but available fertile land (Jagirs) was scarce. | Severe competition among nobles (Be-jagiri); officers extracted excessive taxes from peasantry to make up for shortfalls. |
| Financial Drain | Constant military supply operations, siege maintenance, and bribery consumed the imperial treasury. | Northern provinces were drained of tax revenues, causing agricultural and economic stagnation. |
| Administrative Neglect | Aurangzeb’s prolonged presence in the South left Northern India without direct central oversight. | Local governors (Subahdars) began acting as semi-independent rulers, weakening central authority. |
4. The “Deccan Ulcer” and Imperial Decline
Much like Napoleon’s later “Spanish Ulcer,” the campaign in the Deccan depleted the physical, financial, and political resources of the Mughal state.

When Aurangzeb died in 107 CE at Ahmednagar at the age of 88, he left behind an army exhausted by decades of continuous warfare, a treasury drained by siege operations, and an overextended administrative structure.
5. Historical Significance
The Deccan campaigns marked the turning point of Mughal history. By eliminating the Deccani Sultanates, straining the imperial peasantry through high taxation, and failing to suppress Maratha guerilla tactics, Aurangzeb weakened the institutional foundations built by Akbar and Shah Jahan.
Within decades of his death, regional powers—including the Maratha Empire, the Nizams of Hyderabad, the Nawabs of Bengal, and the Kingdom of Awadh—asserted independence, paving the way for the disintegration of the central Mughal state.
