In the case of Hyderabad, this is the defining situation for a invasion.
n June 1948, Mountbatten prepared the 'Heads of Agreement' deal which offered Hyderabad the status of an autonomous dominion nation under India. The deal called for the restriction of the regular Hyderabadi armed forces along with a disbanding of its voluntary forces. While it allowed the Nizam to continue as the executive head of the state, it called for a plebiscite along with general democratic elections to set up a constituent assembly. The Hyderabad government would continue to administer its territory as before, leaving only foreign affairs to be handled by the Indian government.
Although the plan was approved and signed by the Indians, it was rejected by the Nizam who demanded only complete independence or the status of a dominion under the British Commonwealth.
