The constitutional power to create new states and union territories in India is solely reserved with the Parliament of India, which can do so by announcing new states/union territories, separating territory from an existing state or merging two or more states/union territories or parts of them. As of 2024, there are 28 states and eight union territories in India.

Secession in India typically refers to state secession, which is the withdrawal of one or more states from the Republic of India. Whereas, some have wanted a separate state, union territory or an autonomous administrative division within India. Many separatist movements exist with thousands of members, however, some have low local support and high voter participation in democratic elections. However, at the same time, demanding separate statehood within under the administration of Indian union from an existing state can lead to criminal charges under secession law in India. India is described as an ‘Union of States’ in Article 1 of the Indian constitution I.e "Indestructible nation of destructible states" by its father of constitution Dr. Bhimrao Ramji Ambedkar where a state or Union territory of India cannot secede from India by any means and the Central Government has more powers than the respective state governments and can forcefully change the names and boundaries of the states without their permission at any time when needed for self interest and for the maintenance of integrity.
