Accordingtwo doctrine of subsidiary alliance the adopted son do not have the right to be coronated after the death of the king so due to this the Jhansi Kingdom directly came under British East India company so due to this Jhansi Rani Lakshmi Bai opposed this and that the 1857 first Indian Independence struggle.

Answer 2

Answer: The doctrine of lapse was an annexation policy applied by the British East India Company in India until 1859. According to the doctrine, any Indian princely state under the suzerainty of the British East India Company (the dominant imperial power in the subcontinent), as a vassal state under the British subsidiary system, would have its princely status abolished (and therefore be annexed into British India) if the ruler was either "manifestly incompetent or died without a male heir".
