Centre-State relations

Facts

  • The States Reorganisation Act, 1956 (Act 37 of 1956) was enacted on 31 August 1956 and took effect on 1 November 1956, together with the Seventh Amendment [1][2].
  • India was reorganised into 14 states and 6 union territories, replacing the Part A, B, C and D classification [1].
  • The States Reorganisation Commission, chaired by Fazl Ali with H. N. Kunzru and K. M. Panikkar as members, was appointed in December 1953 and submitted its report on 30 September 1955 [1].
  • According to a cited explainer, the Commission proposed 16 states and three centrally administered areas; the government adopted 14 states and 6 union territories [1].
  • Andhra State, the first formed on a linguistic basis, was created in 1953 after Potti Sreeramulu died in 1952 following a 56-day hunger strike [1].
  • The earlier Linguistic Provinces (Dhar) Commission of 1948 had rejected language as a criterion [1].
  • Later reorganisations include Punjab (1966), Bihar, Madhya Pradesh and Uttar Pradesh (2000), Andhra Pradesh (2014) and Jammu and Kashmir (2019) [1].

Why

Reasons given by those who did it

  • The government appointed the Commission in December 1953 to examine reorganisation after the movement for linguistic states gained momentum following independence and the Andhra agitation [1].
  • The Act and the Seventh Amendment replaced the Part A to D classification with two categories, states and union territories [1].

Criticism of that reasoning

  • The 1948 Dhar Commission had rejected language as a basis for states, indicating that the linguistic principle was disputed before 1956 [1].

Benefits and concerns

Benefits (2)

  • Aligned most state boundaries with major language groups and simplified the constitutional classification of units.Two categories replaced Parts A to D; the Act is the most extensive boundary change since independence, per [1]; text of the Act at [2].
  • Provided a statutory template and procedure that later reorganisations reused.Later Acts for Punjab, Himachal Pradesh, the North-East, 2000 states, Andhra Pradesh and Jammu and Kashmir are listed in [1].

Concerns (2)

  • Boundary demands continued after 1956, with further reorganisations in 1966, 2000, 2014 and 2019.List of later Acts in [1]. Interpretation: whether these reflect unfinished business of 1956 or separate demands is debated and not settled by the sources.
  • The reorganisation followed agitation, including a fatal hunger strike in 1952, after the 1948 Dhar Commission had rejected language as a criterion.Potti Sreeramulu's death and the 1948 Dhar rejection of language as a criterion [1].

Scorer A. Redrew boundaries largely along linguistic lines for the whole country, though further boundary demands followed in later decades.

Scorer B. Boundaries redrawn for the whole country on linguistic lines and still in force, though later reorganisations continued.

Context used when scoring

Era baseline
After 1947 states were grouped into Part A to D classes inherited from provinces and princely states, and linguistic claims had already produced Andhra State in 1953.

In depth

After independence, states were organised as Parts A, B, C and D, based on provinces and princely states. A 1948 commission rejected language as a criterion, but agitation, notably for a Telugu-speaking state, led to the creation of Andhra State in 1953. The government then appointed the States Reorganisation Commission in December 1953.

The Commission reported on 30 September 1955. According to an explainer cited on Wikipedia, it proposed 16 states and three centrally administered areas, while the government adopted 14 states and 6 union territories. Parliament passed the Act on 31 August 1956 and it took effect on 1 November 1956, with the Seventh Amendment replacing the old classification.

The sources reviewed here describe the structure and the later reorganisations but do not give a systematic assessment of governance outcomes, so outcome scoring should be read with caution. Readers should treat claims about administrative or social effects as interpretation rather than established fact.
