subsidiary alliance

A subsidiary alliance was a system used by the East India Company to control Indian states without immediately taking them over.

• Under this arrangement, an Indian ruler accepted a British military force in their territory and had to pay for it. This often placed a heavy financial burden on the state.
• A British official called a Resident stayed at the ruler’s court. Although presented as an adviser, the Resident could strongly influence important decisions.
• The ruler could no longer make alliances, declare war, or deal with other powers independently. Foreign policy was controlled by the British, so the state lost much of its sovereignty—its power to govern itself freely.
• Hyderabad, ruled by the Nizam, entered a subsidiary alliance in 1798. It remained a princely state, but British influence over its affairs became very strong.
• This was different from direct annexation: the Indian ruler stayed on the throne, but real control gradually shifted to the Company. It helped the British expand their power while appearing to protect local rulers.

By turning rulers into dependent allies, the Company could control large areas of India with fewer wars and at the expense of Indian states themselves.
