Before the Indian independence in 1947, India (also called the Indian Empire) was divided into two sets of territories, one under direct British rule (British India), and the other consisting of princely states under the suzerainty of the British Crown, with control over their internal affairs remaining in the hands of their hereditary rulers. The latter included 562 princely states which had different types of revenue-sharing arrangements with the British, often depending on their size, population and local conditions. In addition, there were several colonial enclaves controlled by France and Portugal. After independence, the political integration of these territories into an Indian Union was a declared objective of the Indian National Congress, and the Government of India pursued this over the next decade.
In July 1946, Jawaharlal Nehru pointedly observed that no princely state could prevail militarily against the army of independent India. In January 1947, Nehru said that independent India would not accept the divine right of kings. In May 1947, he declared that any princely state which refused to join the Constituent Assembly would be treated as an enemy state. Vallabhbhai Patel and V. P. Menon were more conciliatory towards the princes, and as the men charged with integrating the states, were successful in the task. Through a combination of factors, Sardar Vallabhbhai Patel and V. P. Menon coerced and coalesced the rulers of the various princely states to accede to India. Having secured their accession, they then proceeded, in a step-by-step process, to secure and extend the union government's authority over these states and transform their administrations until, by 1956, there was little difference between the territories that had been part of British India and those that had been princely states. Simultaneously, the Government of India, through a combination of military and diplomatic means, acquired de facto and de jure control over the remaining colonial enclaves, which too were integrated into India.
