On 20 February 1947, the British government announced its intention to transfer power in British India to Indian hands by June 1948. However by 16 May 1947, the
Cabinet Mission Plan had failed to evolve a constitution for India acceptable to all contending parties. Subsequently, the British government announced on 3 June 1947 its intention to
partition British India into two dominions. On 15 July 1947, the House of Commons passed the
Indian Independence Act 1947, to divide British India into the dominions of
India and
Pakistan. The House of Lords followed suit the next day. The Bill received the Royal assent on 18 July 1947. From this day the
suzerainty of the British Crown over the Indian princely states lapsed as per 7(b) of the India Independence Act 1947, and with it all treaties between the British Crown and the Indian states also had a legal quietus. The rulers of the Indian States became sovereign rulers from 18 July 1947, and in principle they were free to accede to either of the two dominions or to remain independent. As per the provisions of the Act, on 15 August 1947 two independent dominions of India and Pakistan were established. The leaders in the Indian Independence movement put strong pressure on the Indian princes to accede their states to the Dominion of India. By 15 August 1947, virtually all of the rulers had signed an
Instrument of Accession with the
Governor-General of India, giving power to the dominion government to make laws on the three subjects of foreign policy, communication and defence, and otherwise they remained sovereign rulers. These rulers also signed another agreement known as the "Stand Still Agreement", to provide continuity to any existing agreements between British India and their States. Three Indian states namely
Hyderabad,
Jammu and Kashmir, and
Junagadh, failed to accede to either of the dominions. Jammu together with parts of Kashmir was incorporated into India after the Maharaja
Hari Singh was forced to seek Indian military intervention against the marauding Pakistani sponsored tribal lords (Afridis). In time, the two remaining states of Hyderabad and Junagadh were invaded and annexed by India. In 1948 the Maharaja of
Gwalior signed a covenant with the rulers of the adjoining princely states to form a new state known as
Madhya Bharat. This new covenanting state was to be governed by a council of the rulers with a head known as Rajpramukh. This new state signed a fresh Instrument of Accession with the Indian dominion. Subsequently, many other Indian states merged with their neighbouring Indian states on the same lines to form the covenanting states known as
Vindhya Pradesh,
Patiala and East Punjab States Union (
PEPSU),
Rajputana, etc. ==Rajpramukhs in the Republic of India, 1950–1956==
