In short

A political party is an organised group that contests elections to capture governmental power under a declared programme; a pressure group (interest group) organises to influence public policy without contesting elections for office. India's party system has moved from Congress dominance (1952-67) through a dominant-party-with-opposition phase to multi-party coalition politics (1989-2014) and back to a single-party-plus-coalition pattern since 2014. Parties are recognised, regulated and de-recognised by the Election Commission of India under the Election Symbols (Reservation and Allotment) Order, 1968, while defection is policed by the Tenth Schedule inserted by the 52nd Amendment, 1985. This topic carries heavy marks in BA/MA Political Science papers, and it is core general-studies ground for UPSC and State PSC prelims and mains, for Staff Selection Commission and bank general-awareness rounds, and for interviews in journalism, policy research, think tanks, CSR and public-affairs roles.

Phases of the Indian party system

  1. 1952-1967 - the "Congress system" (Rajni Kothari): one-party dominance within a competitive democracy. Congress acted as an umbrella coalition of factions; opposition parties functioned as "parties of pressure" working through Congress factions rather than replacing it. Opposition existed and was free - hence *dominance*, not a one-party state.
  2. 1967-1971 - erosion: the fourth general election broke Congress in eight states, bringing SVD (Samyukta Vidhayak Dal) coalitions, mass defections and the era of "Aya Ram, Gaya Ram".
  3. 1971-1977 - re-centralisation and the Emergency: personalised leadership, the 1969 Congress split, deinstitutionalisation of party organisation.
  4. 1977-1989 - first non-Congress Centre: the Janata Party experiment (1977) showed that coalitions without a common programme collapse; Congress returned in 1980 and 1984.
  5. 1989-2014 - coalition era and the "third electoral system" (Yogendra Yadav): no single-party majority for 25 years; National Front, United Front, NDA (1998, 1999) and UPA (2004, 2009). Regional parties became kingmakers; politics saw the "Mandal-Mandir" churn, OBC assertion and federalisation of the party system.
  6. 2014 onwards - a dominant-party system again: BJP won single-party majorities in 2014 and 2019 and leads the NDA; after the 2024 Lok Sabha election the NDA governs with BJP short of a majority on its own, while the opposition groups as the INDIA bloc. Treat the post-2024 arithmetic as the current position, subject to by-elections and realignments.

Formulas and examples

National party route (a): vote share ≥ 6% of valid votes polled in Lok Sabha or Assembly elections in ≥ 4 States AND Lok Sabha seats ≥ 4
National party route (b): Lok Sabha seats won ≥ 2% of total Lok Sabha seats (that is, ≥ 11 of 543, since 2% of 543 = 10.86, rounded up) from ≥ 3 different States
National party route (c): recognised as a State party in ≥ 4 States
State party route (i): vote share ≥ 6% in the Assembly election AND Assembly seats ≥ 2
State party route (ii): vote share ≥ 6% in the Lok Sabha election from that State AND Lok Sabha seats ≥ 1
State party route (iii): Assembly seats ≥ 3% of the total, or ≥ 3 seats, whichever is more
State party route (iv): Lok Sabha seats ≥ 1 for every 25 seats (or part thereof) allotted to that State
State party route (v): vote share ≥ 8% of valid votes polled in the State (Assembly or Lok Sabha) - the vote-share-only route
Tenth Schedule merger: members agreeing to merge ≥ (2/3) × strength of the legislature party
Council of Ministers ceiling (Articles 75(1A), 164(1A)): size ≤ 0.15 × total strength of the House; for a State, minimum 12
Vote share (%) = (valid votes polled for the party / total valid votes polled) × 100
Seat-vote disproportionality (Loosemore-Hanby index) = ½ × Σ |seat share % − vote share %|

Example 1 - does a party qualify as a national party by the seats route? A party wins 14 Lok Sabha seats in a House of 543, drawn from Tamil Nadu, Kerala and Puducherry.

Example 2 - state party status by the Assembly route. In a 234-member Assembly a party polls 5.4% of valid votes and wins 8 seats.

Example 3 - the two-thirds merger test under the Tenth Schedule. A party has 40 MLAs. Twenty-six of them sign a letter claiming a merger with another party.

Example 4 - Council of Ministers ceiling. Lok Sabha strength 543; Uttar Pradesh Assembly 403; Sikkim Assembly 32.

Example 5 - seat-vote distortion in a first-past-the-post system. Three parties in a 100-seat House: A - 38% votes, 55 seats; B - 32% votes, 30 seats; C - 30% votes, 15 seats.
