Explanation: The East India Company’s harsh conditions imposed on the state of Travancore, after both agreed to a subsidiary alliance arrangement under Wellesley in 1805, caused deep resentment in the region.

• The ruler was not able to pay the subsidy and fell in arrears. The British resident of Travancore was meddling in the internal affairs of the state.
• The high-handed attitude of the Company compelled Prime Minister (or Dalawa) Velu Thampi to rise against the Company, assisted by the Nair troops.
