Question

what was meant by the subsidiary forces that the company wanted to keep in the Indian states​

Answer 1

Answer:  

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.[1]

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 Company's 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[2]:

Answer 2

Answer:

Subservience – Submissiveness had to pay for the “subsidiary forces” that the Company was supposed to maintain for the purpose of this protection. If the Indian rulers failed to make the payment, then part of their territory was taken away as penalty.
