Explanation:

The general policy of the Indian National Congress (INC) towards the Indian princely states was first enunciated in 1920 at Nagpur and later carried forward till independence. It was first of exhortation for a responsible government in the states and later active political intervention. It called upon the Princes to grant full responsible government in their States. However, no direct political activity was to be resorted for. This position continued till 1935. Two developments in the mid-30s brought a radical change in the relations between the Princely States and British India. The Government of India Act of 1935 projected a scheme of federation in which the States were brought into a direct constitutional relationship with British India. The second major impact on the States was created by the acceptance of office by the Congress in majority of the British Indian provinces in 1937 The installation of the Congress ministries in the neighbouring British Indian provinces encouraged the Praja Mandal leaders to step up their political activities for demanding responsible government in the Princely States
