how did the policy of subsidiary Alliance support the expansion of British Empire in India
Answers
A subsidiary alliance, in South Asian history, describes a tributary alliance between a Native state and either French India, or later the British East India Company. The pioneer of the subsidiary alliance system was French Governor Joseph François Dupleix, who in the late 1740s established treaties with the Nizam of Hyderabad, and Carnatic.
The methodology was subsequently adopted by the East India Company, with Robert Clive imposing a series of conditions on Mir Jafar of Bengal, following the 1757 Battle of Plassey, and subsequently those in the 1765 Treaty of Allahabad, as a result of the Companies success in the 1764 Battle of Buxar. A successor of Clive, Richard Wellesley initially took a non-interventionist policy towards the Native states but later adopted, and refined the policy of forming subsidiary alliances. The purpose and ambition of this change are stated in his February 1804 dispatch to the East India Company Resident in Hyderabad:
His Excellency the Governor-General's policy in establishing subsidiary alliances with the principal states of India is to place those states in such a degree of dependence on the British power as may deprive them of the means of prosecuting any measures or of forming any confederacy hazardous to the security of the British empire, and may enable us to reserve the tranquility of India by exercising a general control over those states, calculated to prevent the operation of that restless spirit of ambition and violence which is the characteristic of every Asiatic government, and which from the earliest period of Eastern history has rendered the peninsula of India the scene of perpetual warfare, turbulence and disorder...
Richard Wellesley, 4th February 1804
In a subsidiary alliance, princely rulers were not allowed to make any negotiations and treaty with any other ruler. They were also not allowed to have an independent armed force. They were to be protected by the East India Company but had to pay for the subsidiary forces that the company was to maintain for protection. If Indian rulers failed to make the payment, part of their territory was taken away as penalty. For example, the Nawab (ruler) of Awadh was forced to give over half of his territory to the company in 1801, reason provided by British officer was Maladministration. Hyderabad was also forced to cede territories on similar grounds.
By the late 18th century, the power of the Maratha Empire had weakened and the Indian Subcontinent was left with a great number of states, most small and weak. Many rulers accepted the offer of protection by Wellesley, as it gave them security against attack by their neighbours.The alliance was forced upon rulers so their territories could be annexed by the British
