Doab Taxation

The Doab, the fertile alluvial tract between the Ganges and Yamuna rivers, served as the primary revenue source for the Delhi Sultanate. In 1326 AD, Sultan Muhammad bin Tughlaq initiated a significant restructuring of the land revenue system in this region to augment the state’s financial resources.

Administrative Objectives

The Sultan’s decision to increase taxation in the Doab was driven by several systemic requirements:

• Fiscal consolidation to address the dwindling state treasury.
• Funding for expansive administrative projects and military campaigns, including the planned expeditions into Central Asia and the Deccan.
• Standardization of land revenue collection based on the high agricultural productivity of the region.

Nature and Scope of Tax Reforms

The administration implemented a multifaceted approach to revenue extraction:

• Revenue enhancement: Historical records suggest an increase in taxation ranging from 5 to 10 times the previous rates.
• Cess implementation: New cesses or surcharges were introduced alongside the traditional land tax (kharaj).
• Rigorous collection: The state utilized a centralized machinery to ensure full compliance, often employing harsh measures against defaulting peasants.

The Confluence of Crisis

The implementation of these tax reforms suffered from a lack of foresight regarding local agricultural cycles and climatic conditions:

• Famine onset: The timing of the tax increase coincided with a severe, prolonged famine in the Doab region caused by the failure of seasonal rains.
• Peasant resistance: Unable to meet the exorbitant tax demands, the farming population abandoned their fields (khet-haris) and fled into the forests.
• Rural unrest: The abandonment of agriculture led to widespread agrarian uprisings, effectively turning the fertile Doab into a region of desolation.

State Response and Mitigation

Recognizing the failure of the policy and the resulting collapse of agricultural output, the Sultan attempted to introduce remedial measures:

• Creation of the Diwan-i-Kohi: A dedicated Department of Agriculture was established to oversee land reclamation.
• Financial incentives: The state introduced agricultural loans known as Sondhar or Saundhar to help farmers procure seeds, cattle, and implements.
• Crop diversification: The administration encouraged the cultivation of high-value crops, such as sugarcane and grapes, instead of traditional inferior cereals.
• Infrastructure investment: The state financed the digging of wells and provided irrigation support to stabilize production.

Socio-Economic Consequences

The Doab taxation policy had profound implications for the Tughlaq state:

• Revenue failure: The cost of providing relief and loans, combined with the loss of potential land revenue, resulted in a net deficit for the state.
• Administrative instability: The failure eroded the Sultan’s authority and contributed to the narrative of his “misguided” administrative reforms among both contemporary scholars and historical chroniclers.
• Loss of credibility: The inability to successfully implement agrarian reforms weakened the state’s control over its most vital economic base.

Summary of Key Factors

Historical Perspective

Chroniclers like Ziauddin Barani highlight that the harshness of the tax collection and the failure to adjust for famine conditions were primary catalysts for the internal disintegration of the Tughlaq Empire. This event is often cited as a classic case in medieval Indian history where a theoretically sound administrative goal (increasing revenue) led to catastrophic failure due to poor implementation and a lack of sensitivity to local environmental and social realities.
