Salute state
A salute state was a princely state under the British Raj that had been granted a gun salute by the British Crown (as paramount ruler); i.e., the protocolary privilege for its ruler to be greeted—originally by Royal Navy ships, later also on land—with a number of cannon shots, in graduations of two salutes from three to 21, as recognition of the state's relative status. The gun-salute system of recognition was first instituted during the time of the East India Company in the late 18th century and was continued under direct Crown rule from 1858.
