Evolution of States and Union Territories

At the time of independence, India had 2 types of political units, namely, the British Provinces and the Princely States. Later on, the Indian Independence Act of 1947 led to the
formation of two independent and separate dominions, namely, India and Pakistan. Three options were available to the Princely States :

1. Joining India
2. Joining Pakistan
3. Remaining Independent

Total Number of Princely states were 552
Total Princely States that joined India were 549

Princely states of Hyderabad, Junagarh and Kashmir refused to join India. But later on, Hyderabad was integrated to India by means of police actions, Junagarh by means of referendum and Kashmir by the Instrument of Accession.

When the Indian Constitution came into force, it contained a fourfold classification of the States of the Indian Union :
