1. The Structural Crisis of the Mughal Empire
By the closing years of the seventeenth century, the once invincible Mughal Empire was engulfed in a multifaceted, terminal crisis. The root cause of this decline was Emperor Aurangzeb's protracted and disastrous military campaign in the Deccan (lasting over twenty-five years), which completely depleted the empire's vast imperial treasury and squandered its finest military resources.
This prolonged imperial overreach triggered the breakdown of the foundational mansabdari administrative machinery:
- The Jagir Crisis (Be-jagiri): The number of appointed mansabdars escalated dramatically, but the availability of fertile crown agricultural land (khalisa) and assignable revenue estates (jagirs) shrank drastically. Mansabdars often waited years for jagir assignments, leading to intense competition, corrupt revenue inflation, and relentless extortion of peasant cultivators.
- Erosion of Imperial Control: Powerful provincial governors (subadars) increasingly controlled both civil administration (subadari) and military-fiscal offices (diwani and faujdari). They monopolized regional land revenues, withheld remittances to the imperial capital in Delhi, and built autonomous provincial power centers.
- Peasant and Zamindar Rebellions: Throughout northern and western India, oppressed peasant communities, often mobilized by assertive local chieftains and zamindars (such as the Jats, Sikhs, and Satnamis), mounted armed rebellions against exorbitant imperial taxation.
2. Factionalism at Court: Iranis, Turanis, and Kingmakers
Following Aurangzeb's death in 1707 CE, the central throne fell into the hands of a succession of weak, inept monarchs termed the Later Mughals. The imperial court in Delhi fragmented into vicious, self-serving aristocratic cliques divided into two rival factions: the Iranis (nobles of Persian origin) and the Turanis (nobles of Central Asian Turkish origin).
The emperors became pathetic puppets manipulated by ambitious grandees. The most notorious manifestation of this courtly decay was the rise of the Sayyid brothers—Abdullah Khan and Husain Ali Khan—known in history as the "Kingmakers". Between 1713 and 1719 CE, the Sayyid brothers enthroned, controlled, blinded, and assassinated emperors at will (including Jahandar Shah and Farrukh Siyar), exposing the utter impotence of central authority.
3. Foreign Invasions: Nadir Shah (1739) and Ahmad Shah Abdali
Taking full advantage of Delhi's internal paralysis, devastating foreign invaders struck catastrophic blows against the empire:
- Nadir Shah's Invasion (1739 CE): The ruler of Iran, Nadir Shah, invaded India in 1739, easily routed the imperial army at the Battle of Karnal, and marched into Delhi. Nadir Shah orchestrated a horrific massacre of Delhi's citizens and systematically plundered the imperial treasury, looting gold, jewels, and priceless imperial heirlooms—including the legendary Koh-i-Noor diamond and Shah Jahan's jewel-encrusted Peacock Throne (Takht-i Taus)—draining an estimated 70 crore rupees of wealth.
- Ahmad Shah Abdali's Raids (1748–1761 CE): Following Nadir Shah, the Afghan monarch Ahmad Shah Abdali invaded northern India five separate times between 1748 and 1761, plundering Punjab, Mathura, and Delhi, and turning northern India into an anarchic war zone.
