Key concepts

The first general election

NCERT section Challenge of Building Democracy

Background: the Constitution was adopted on 26 November 1949, signed on 24 January 1950 and came into effect on 26 January 1950; an interim government ruled until elections.

• Election Commission set up in January 1950; Sukumar Sen became the first Chief Election Commissioner. Elections were expected in 1950 itself.

Difficulties:

• Delimitation of constituencies and preparing electoral rolls took time.
• The first draft rolls left out nearly 40 lakh women, listed only as 'wife of' or 'daughter of'; the Commission refused such entries and ordered revision.
• Scale: 17 crore eligible voters electing about 3,200 MLAs and 489 Lok Sabha members; only 15 per cent literate, so a special voting method was needed. Over 3 lakh officers and staff were trained.
• It was the first big test of democracy in a poor and illiterate country.

Voting methods: first, a box for each candidate with his symbol (about 20 lakh steel boxes); after two elections, a ballot paper with all names and symbols to be stamped (used for nearly 40 years); the EVM from the late 1990s, country-wide by 2004.

Sceptics: an Indian editor called it 'the biggest gamble in history'; others predicted failure of universal adult franchise.

Result: held October 1951 to February 1952 (called the 1952 election), after two postponements; it took six months. Competitive (more than four candidates per seat on average); more than half the voters turned out; results were accepted even by losers. It became a landmark in world democracy, proving elections could be held amid poverty and illiteracy.

Worked example

Why was the first general election of 1952 a landmark in the history of democracy? (2 marks)

Try it first, then show the solutionSolution

1. It was the largest election held anywhere till then (17 crore voters, only 15 per cent literate), in a poor country, which sceptics called the biggest gamble in history.
2. It was competitive, had more than half the voters turning out, and its results were accepted as fair even by losers, proving democracy could work amid poverty and illiteracy.

Answer: It proved that free and fair elections could be held in a poor, largely illiterate country on a huge scale.

Congress dominance in the first three elections

NCERT section Congress Dominance in the First Three General Elections

1952: the Congress was expected to win because it inherited the legacy of the national movement, was the only party with a nationwide organisation, and had Nehru, the most popular and charismatic leader. The size of victory still surprised many: 364 of 489 Lok Sabha seats. The CPI, next, won only 16.

• In state elections it won majorities everywhere except Travancore-Cochin, Madras and Orissa, yet formed governments even there. Nehru became PM.

1957 and 1962: the Congress kept about three-fourths of Lok Sabha seats; no opposition party won even one-tenth of the Congress's seats. In states it lost a few cases, the most significant being Kerala (1957).

Role of the electoral system (first-past-the-post):

• In 1952 the Congress got 45 per cent of votes but 74 per cent of seats; the Socialist Party, second in votes with over 10 per cent, got less than 3 per cent of seats.
• Under FPTP the party with more votes than others gets far more than its proportional share. Non-Congress votes together exceeded Congress votes but were divided among rivals.

Box: Communist victory in Kerala (1957): CPI won 60 of 126 seats with support of five independents; E. M. S. Namboodiripad became Chief Minister: the first time in the world a Communist government came to power through democratic elections. The Congress launched a 'liberation struggle'; in 1959 the Centre dismissed the government under Article 356, widely cited as a misuse of emergency powers.

Worked example

How did the electoral system exaggerate the Congress's victory? (2 marks)

Try it first, then show the solutionSolution

1. Under the first-past-the-post system, the party with the most votes in a seat wins, so a leading party gets far more than its share of votes: in 1952 the Congress got 45 per cent of votes but 74 per cent of seats.
2. Non-Congress votes, though larger in total, were divided among many rival parties and candidates; the Socialist Party got over 10 per cent of votes but under 3 per cent of seats.

Answer: FPTP and a divided opposition turned 45 per cent of votes into 74 per cent of seats.

Nature of Congress dominance

NCERT section Nature of Congress Dominance

Unlike other one-party dominance: in many countries dominance came by compromising democracy: in China, Cuba and Syria the constitution permits only one party; Myanmar, Belarus, Egypt and Eritrea are effectively one-party states through legal and military measures; Mexico, South Korea and Taiwan were dominant-party states until recently. India's case was different: the Congress dominated under democratic conditions, winning free and fair elections against many parties, similar to the African National Congress in South Africa after apartheid.

Roots of its success:
1. Legacy of the freedom struggle: seen as inheritor of the national movement; many movement leaders were its candidates.
2. Organisation: already well organised, with a network down to the local level across the country.
3. 'First off the blocks' advantage: many parties were formed only around or after Independence.
4. All-inclusive nature, as a former national movement.

Worked example

How was the Congress's dominance in India different from one-party dominance in other countries? (2 marks)

Try it first, then show the solutionSolution

1. Elsewhere, one-party dominance was ensured by compromising democracy: constitutions allowing a single party (China, Cuba, Syria) or legal and military measures (Myanmar, Belarus, Egypt, Eritrea).
2. In India, the Congress dominated under democratic conditions, winning free and fair elections in which many parties competed.

Answer: Indian dominance came through free and fair elections, not by suppressing democracy.

Congress as a social and ideological coalition

NCERT section Congress as Social and Ideological Coalition

Social coalition:

• Founded in 1885 as a pressure group of the newly educated, professional and commercial classes, it became a mass movement in the 20th century and then a mass party.
• It began dominated by the English-speaking, upper-caste, upper-middle-class, urban elite, but each civil disobedience movement widened its social base.
• Peasants and industrialists, urban and rural people, workers and owners, all classes and castes found space in it; leadership expanded to rural, agriculture-based leaders.
• By Independence it was a 'rainbow-like' social coalition reflecting India's diversity of classes, castes, religions, languages and interests.

Ideological coalition:

• Many groups kept their own beliefs within it: revolutionary and pacifist, conservative and radical, extremist and moderate, right, left and centre.
• It was a 'platform' for groups and even parties; before Independence, organisations with their own constitutions were allowed inside it (e.g. the Congress Socialist Party, which later left).
• Despite differences, it managed to contain if not resolve them and build consensus.

Worked example

Explain how the Congress was a social coalition. (2 marks)

Try it first, then show the solutionSolution

1. It began as a party of the English-speaking, upper-caste, urban elite, but its social base widened with each mass movement.
2. By Independence it included peasants and industrialists, workers and owners, villagers and city-dwellers, and all classes, castes, religions and languages: a rainbow-like coalition.

Answer: It brought together diverse and often conflicting social groups, reflecting India's diversity.

Tolerance and management of factions: the Congress system

NCERT section Tolerance and Management of Factions

Coalition-like character gave unusual strength:
1. A coalition must avoid extreme positions and strike a balance; compromise and inclusiveness are its hallmarks. Whatever the opposition said found a place in the Congress programme, putting the opposition in difficulty.
2. A coalition tolerates internal differences and accommodates ambitions. So unhappy groups stayed inside the party and fought other groups rather than leaving to become an opposition.

Factions: groups inside the party, some ideological but often rooted in personal ambitions and rivalries. The Congress tolerated and even encouraged them.

• Instead of weakness, factionalism became a strength: leaders of different interests stayed inside rather than forming new parties.
• State units were made up of many factions with different ideologies, making the Congress a grand centrist party.
• Other parties tried to influence these factions and so influenced policy from the 'margins'; they were not alternatives but pressurised, criticised and influenced the Congress.
• The faction system worked as a balancing mechanism; political competition took place within the Congress.

'Congress system': in the first decade, the Congress acted as both the ruling party and the opposition.

Worked example

How did factionalism become a strength of the Congress? (4 marks)

Try it first, then show the solutionSolution

1. Factions were groups within the party, based on ideology or personal ambitions and rivalries.
2. Because the party tolerated them, unhappy groups fought within the party instead of leaving to form opposition parties.
3. Factions with different ideological positions made the Congress a grand centrist party, and acted as a balancing mechanism within it.
4. Opposition parties influenced policy indirectly by influencing factions; competition took place within the Congress, which acted as both ruling party and opposition: the 'Congress system'.

Answer: By keeping diverse leaders inside the party and providing internal competition and balance, factions strengthened Congress dominance.

Emergence of opposition parties

NCERT section Emergence of Opposition Parties (with boxes)

India had a larger number of diverse, vibrant opposition parties than many multi-party democracies; most of today's non-Congress parties trace roots to them. They won only token representation, yet:

• Offered sustained, principled criticism, keeping the ruling party in check and often changing the balance within the Congress.
• Kept a democratic alternative alive, preventing resentment from turning anti-democratic.
• Groomed leaders who later shaped the country.
• There was mutual respect: the interim government included Ambedkar and Shyama Prasad Mukherjee; Nehru invited Jayaprakash Narayan to join his government. Such respect declined as competition intensified.

Socialist Party: roots in the Congress Socialist Party (1934), formed within the Congress by young leaders wanting a more radical, egalitarian Congress. When the Congress barred dual membership in 1948, the Socialists formed a separate party. Ideology: democratic socialism; criticised the Congress for favouring capitalists and landlords. Dilemma when the Congress adopted the 'socialist pattern of society' (1955): Lohia increased criticism; Asoka Mehta favoured limited cooperation. Many splits (Kisan Mazdoor Praja Party, Praja Socialist Party, Samyukta Socialist Party). Leaders: JP, Achyut Patwardhan, Asoka Mehta, Acharya Narendra Dev, Lohia, S. M. Joshi. Samajwadi Party, RJD, JD(U) and JD(S) trace origins to it.

Communist Party of India: communist groups emerged in the early 1920s inspired by the Bolshevik revolution; worked within the Congress from 1935; parted in December 1941 by supporting the British against Nazi Germany. After 1947 it saw independence as not true freedom and encouraged violent uprisings in Telangana, which were crushed; in 1951 it gave up violent revolution to contest elections, winning 16 seats in 1952 as the largest opposition party (support in Andhra Pradesh, West Bengal, Bihar, Kerala). Leaders included E. M. S. Namboodiripad, S. A. Dange and A. K. Gopalan, along with Ajay Ghosh, P. Sundarraya and P. C. Joshi. Split in 1964 (Soviet-China rift): CPI and CPI(M).

Bharatiya Jana Sangh: formed 1951, founder-President Shyama Prasad Mukherjee; lineage from the RSS and Hindu Mahasabha. Ideas: one country, one culture, one nation; modernity based on Indian culture; Akhand Bharat; replacing English with Hindi as official language; opposed concessions to religious and cultural minorities; advocated nuclear weapons, especially after China's 1964 tests. Won only 3 seats (1952) and 4 (1957); support in urban Hindi-speaking areas. Leaders: Mukherjee, Deen Dayal Upadhyaya (integral humanism), Balraj Madhok. The BJP traces its roots to it.

Worked example

What role did opposition parties play during the era of one-party dominance? (4 marks)

Try it first, then show the solutionSolution

1. Though they won only token seats, they offered sustained and principled criticism of Congress policies and practices.
2. This kept the ruling party in check and often changed the balance of power within the Congress.
3. By keeping a democratic alternative alive, they prevented resentment with the system from turning anti-democratic.
4. They groomed leaders who later played crucial roles; mutual respect was visible, e.g. Ambedkar and Mukherjee in the first cabinet.

Answer: They checked the Congress, kept democracy alive with alternatives and trained future leaders.

   Assertion (A): The Socialists faced a dilemma after 1955.
   Reason (R): The Congress declared its goal to be the socialist pattern of society.
   Choose (a)-(d).

   Hint

   Hard to be an alternative.

   Answer

   (a) Both are true and R explains A: it became difficult for the Socialists to present themselves as an effective alternative.

4. Q4 · 2 marks · Very short answerBoard level

   Name two states where the Congress was not in power at some point during 1952-67, and explain one case. (2 marks)

   Hint

   Kerala 1957.

   Answer

   Kerala, where a CPI-led government under E. M. S. Namboodiripad took office in 1957 (dismissed in 1959 under Article 356). In 1952 the Congress lacked a majority in Travancore-Cochin, Madras and Orissa, though it formed governments there. (Teachers may accept other states from the textbook map.)

5. Q5 · 2 marks · Very short answerBoard level

   What were the main ideas of the Bharatiya Jana Sangh? (2 marks)

   Hint

   One nation.

   Answer

   One country, one culture and one nation; modernisation based on Indian culture and traditions; reunion of India and Pakistan in Akhand Bharat; Hindi to replace English as official language; opposition to concessions to religious and cultural minorities; and development of nuclear weapons.

6. Q6 · 4 marks · Short answerHOTS / competency

   Suppose a school election has one big group that includes students from every class and club, and several small groups that win only one or two seats each. Using the Congress system, explain why the big group keeps winning and what the small groups can still achieve. (4 marks)

   Hint

   Coalition, FPTP, opposition role.

   Answer

   Like the Congress, the big group is a coalition that accommodates everyone and avoids extremes, so it absorbs others' ideas; internal factions compete within it rather than leaving. Its votes may be under half, but with a divided opposition, first-past-the-post gives it most seats (as 45 per cent votes gave 74 per cent seats in 1952). The small groups can still criticise, keep it in check, shift the balance among its factions, keep alternatives alive and train future leaders.

7. Q7 · 1 mark · Assertion-reasonHarder board level

   Assertion (A): Opposition parties in the 1950s had little influence on government policy.
   Reason (R): They won only token representation in the Lok Sabha and state assemblies.
   Choose (a)-(d).

   Hint

   Influence from the margins.

   Answer

   (d) A is false but R is true: despite token seats, they influenced policy by criticising the Congress and pressuring its factions.

8. Q8 · 4 marks · Short answerHarder board level

   Trace the journey of the Communist Party of India from its origins to 1964. (4 marks)

   Hint

   Bolshevik inspiration to split.

   Answer

   Communist groups emerged in the early 1920s inspired by the Bolshevik revolution. From 1935 they worked within the Congress, but parted in December 1941 by supporting the British against Nazi Germany. After Independence, the party saw the transfer of power as not true independence and encouraged violent uprisings in Telangana, which were crushed. In 1951 it abandoned violent revolution and contested elections, winning 16 seats in 1952 as the largest opposition party. In 1964 it split after the Soviet-China rift into the CPI (pro-Soviet) and CPI(M).
