State Formation in India: Formation of States in India in Chronological Order, 28 States

By Balaji

Updated on: February 17th, 2023

State Formation In India began in 1947 at the time of Independence when India consisted of 571 disjointed princely states, which were later merged. Initially, the Formation of States in India was based on political and historical considerations rather than a linguistic or cultural division. But that organization lasted only for a short term.

After some time, there were demands from people for several different States’ Formations in India because of diverse reasons. Also, it was felt by the government to look into the need for the organization of states on a linguistic basis, as the regions of the country were multilingual. As a result, several committees were formed, and acts were passed on whose basis State Formation in India was completed.

State Formation in India on Linguistic Grounds

Several attempts were made and rejected to form States in India based on linguistic grounds. Two distinct bodies were set up to evaluate the requirements for the division of Indian states based on the languages of the folks.

Formation of States Dhar Commission – Linguistic Provinces Commission

On June 17, 1948, the linguistic province’s commission was set by the constituent assembly to look into the need to form states on a linguistic basis. S. K. Dhar, the judge of Allahabad High court, was appointed as the head. On December 10, 1948, the commission submitted a report.

The Dhar commission rejected the idea of reorganization based on language and suggested it be done based on administrative convenience, including historical and geographical considerations.

India State Formation JVP Committee

By December 1948, the JVP Committee was formed to re-examine the need for reorganising Indian states on a linguistic basis and study the recommendations of the Dhar Commission. The committee consisted of Jawaharlal Nehru, Vallabhbhai Patel, and Pattabhi Sitaramayya.

The committee submitted its report in April 1949, according to which the plan of division based on language got rejected.

Linguistic States Formation in India

As the government dissolved the plan to form states in India based on linguistic division, there were protests in several regions. The Kannada, Malayalam, and Marathi-speaking people wanted their state. Over time the agitation got intense.

The most vigorous protest came from that of the Telugu-speaking people from the region, which was back then the Madras Presidency. During the 1952 general election propaganda, the people of this region showed their disagreement with Nehru with black flags and raised demand for a separate state of Andra for the Telugu-speaking people.

The Hunger Strike: By October, an individual named Potti Sriramalu, a veteran Gandhian, went on a hunger strike seeking a separate state of Andra for the Telugu speakers. The strike went on for 58 days. More people gathered for support, and there were protests in various towns. Finally, on December 15, 1952, Potti Sriramalu faced death due to a hunger strike. Unable to control the widespread protest, the government was forced to accept their demand.

The state of Andhra Pradesh was formed on October 1, 1953. It was the first state to be included on a Linguistic basis.

Reorganization Commission for States Formation in India

With the formation of the linguistic state of Andhra Pradesh, there were similar demands for creating states based on language all over the country. By December 1953, Jawaharlal Nehru formed the States Reorganization Commission (SRC) to study the new demands. The commission consisted of Fazil Ali, H.N. Kunzru, and K.M. Panikkar.

The commission submitted its report by 1955. Its main idea was to protect unity, integrity, linguistic and cultural homogeneity, and financial, economic, and administrative viability. Based on its report, it came up with a recommendation of dividing the country into 16 states and three centrally administered areas.

States Reorganization Act, 1956

The government didn’t agree with the recommendation of the state reorganization commission to divide the country into 14 states and six union territories under the States Reorganization Act, 1956. According to this act, the boundaries of Indian states and territories were organized on linguistic lines.

The states formed under States Reorganization Act were:

  1. Andhra Pradesh
  2. Assam
  3. Bihar
  4. Bombay
  5. Jammu and Kashmir
  6. Kerala
  7. Madhya Pradesh
  8. Madras
  9. Mysore
  10. Orissa
  11. Punjab
  12. Rajasthan
  13. Uttar Pradesh
  14. West Bengal

The union territories formed under States Reorganization Act were:

  1. Andaman and Nicobar Islands
  2. Delhi
  3. Himachal Pradesh
  4. Laccadive
  5. Minicoy
  6. Amindivi Islands
  7. Manipur
  8. Tripura

Jammu and Kashmir Reorganization Act

Until 2019 Jammu and Kashmir exercised special powers under article 35A. It empowered the state’s legislature to define permanent residents of the state and enable them to exercise extraordinary powers and privileges. In addition, the state has its constitution and separate land inheritance law.

On August 5, 2019, the Minister of Home Affairs, Amit Shah, introduced the Jammu and Kashmir reorganization bill in the Rajya Sabha. As a result, article 370, including article 35A, got revoked. Further, the bill aimed at reorganizing the state of Jammu and Kashmir into the union territory of Jammu and Kashmir (with assembly) and the union territory of Ladakh (without assembly).

The major takeaways after Article 370 revoke are:

  • No dual citizenship
  • Central law can directly apply
  • No separate laws
  • Indian citizens from other states can buy land and property
  • No two flags
  • Election every five years
  • The centre can declare a financial emergency under article 360
  • The centre will manage police

Challenges in State Formation in India

Prime Minister Nehru and Deputy Prime Minister Vallabhbhai Patel were against forming linguistic states.

It was evident that during the freedom struggle, the most influential parties of the time – the Indian National Congress in 1920, had promised the formation of provinces on a linguistic basis right after independence. But later, the party’s ideas changed; they were against the formation of the linguistic state.

The change in the decision was mainly due to the communal riots that broke out during the post-colonial period. Freedom came along with partition, which caused lots of bloodshed. The entire country was divided into two parts based on religion. There was forced displacement, and many crimes were committed, killing millions of people.

This created distress in the minds of people. Nehru and Vallabhbhai Patel feared that the linguistic formation of states would once again cause a division among people. They perceived linguistic states as obstacles that would divide people. So they wanted to promote the idea of nationalism to have everyone united and reject any place that would bring about division.
