In October 1947, Pakistan sent tribal infiltrators from its side to capture Kashmir.

In October 1947, Pakistan sent tribal infiltrators from its side to capture Kashmir. This forced the Maharaja to ask for Indian military help. India extended the military support and drove back the infiltrators from Kashmir valley, but only after the Maharaja had signed an ‘Instrument of Accession’ with the Government of India. However, as Pakistan continued to control a sizeable part of the state, the issue was taken to the Union Nations Organisation, which in its resolution dated 21 April 1948 recommended a three step process to resolve the issue. Firstly, Pakistan had to withdraw its entire nationalities, who entered into Kashmir. Secondly, India needed to progressively reduce its forces so as to maintain law and order. Thirdly, a plebiscite was to be conducted in a free and impartial manner. However, no progress could be achieved under this resolution. In the meanwhile, Sheikh Abdullah took over as the Prime Minister of the State of J&K in March 1948 while India agreed to grant it provisional autonomy under the Article 370. The head of the government in the State was then called Prime Minister.
