Political Processes in Sri Lanka: From Democracy to Radicalism

Sri Lanka is one of the oldest democracies in South Asia, holding regular elections and peaceful transfers of power since independence in 1948. Yet behind this democratic façade lies a turbulent story of majoritarian politics, ethnic conflict, armed insurrection, and elite dominance. The island nation shows how a multi-ethnic democracy, when captured by the interests of a numerical majority, can slide from competitive electoral politics into prolonged violence. Understanding these political processes means tracing how language, religion, and economic grievances became the fault lines along which the country fractured.

The architecture of majoritarian democracy

Sri Lanka inherited a Westminster-style parliamentary system from British rule. On paper, this guaranteed competitive elections and representative government. In practice, the system quickly evolved into what scholars describe as a majoritarian democracy, where the numerical strength of one community translates directly into near-total control over the state.

The demographics explain why. The Sinhalese, who are predominantly Buddhist, make up roughly three-quarters of the population. Tamils, who are mostly Hindu, and Muslims form the largest minorities. In a first-past-the-post system without strong protections for minority rights, the majority could win power repeatedly without ever needing minority support. Political parties soon discovered that appealing to Sinhala-Buddhist sentiment was the surest route to electoral victory.

Language as the first fault line

The clearest expression of majoritarianism came through language policy. Before independence, there had been broad agreement that both Sinhala and Tamil would serve as official languages. That consensus collapsed. In 1956, the government passed the Official Language Act, popularly called the “Sinhala Only” Act, making Sinhala the sole official language of the state.

The consequences were immediate and far-reaching. Tamil speakers were effectively shut out of government jobs, higher education, and public administration, since proficiency in Sinhala became a gateway to opportunity. The move was framed by Sinhala nationalists as a corrective measure to reverse colonial-era imbalances, but to Tamils it amounted to systematic discrimination embedded into law. Language, the most basic marker of identity, became the first major grievance that pushed the Tamil community toward demands for autonomy.

Citizenship, religion, and accumulating grievances

The marginalisation went deeper than language. As early as 1949, the government disenfranchised the Indian Tamil plantation workers, who had been brought over during British rule and made up a sizeable share of the population, stripping them of citizenship and voting rights. The state also actively promoted Buddhism, marginalising Hindu, Christian, and Muslim communities. Development policies channelled resources toward Sinhalese-majority areas, and electoral boundaries reduced Tamil political influence.

These were not isolated decisions. Together they formed a pattern in which minorities watched their political weight, economic prospects, and cultural rights shrink decade after decade. When peaceful constitutional avenues for redress repeatedly failed, more radical alternatives gained appeal.

Tamil militancy and the rise of the LTTE

For nearly twenty-five years, Tamil political leaders pursued a campaign for federalism, hoping that regional autonomy within a united Sri Lanka would protect their community. This campaign failed. The Sinhalese political class largely viewed Tamil demands for autonomy as illegitimate, while the Jayewardene government elected in 1977 pushed in the opposite direction, centralising power through a powerful executive presidency created in 1978.

With federalism off the table, the Tamil movement transformed into a struggle for a separate state. Out of this frustration emerged the Liberation Tigers of Tamil Eelam (LTTE), which sought an independent Tamil homeland called Tamil Eelam in the north and east. Anti-Tamil riots in 1983, often called “Black July,” marked the descent into full-scale war.

A 26-year civil war

The conflict that followed was one of the longest and bloodiest civil wars in modern Asia. The LTTE’s armed struggle from 1983 to 2009 devastated the country, claiming over 100,000 lives and displacing hundreds of thousands of people. The Tigers became infamous for pioneering suicide bombing as a tactic and for assassinating political leaders, including former Indian Prime Minister Rajiv Gandhi.

The war exposed a hard truth about Sri Lankan democracy: institutions that looked democratic on the surface could fail completely to protect minority rights. When the majority controlled every lever of the state and minorities saw no peaceful path to security, some turned to violence as the only perceived alternative. The war finally ended in 2009 with the military defeat of the LTTE, but the underlying grievances were never fully addressed.

Sinhala youth radicalism and the JVP

Militancy in Sri Lanka was not confined to the Tamil minority. A parallel and often overlooked story is that of Sinhala youth radicalisation. The Janatha Vimukthi Peramuna (JVP), or People’s Liberation Front, was a Marxist-Leninist movement founded in 1965 by Rohana Wijeweera, a former medical student who had studied in the Soviet Union.

The JVP drew its support not from ethnic grievance but from class anger. Rural Sinhalese youth, many of them educated yet unemployed, felt locked out of an economy and a political system dominated by an entrenched elite. The party promised a socialist revolution that would sweep away this establishment.

Two insurrections

The JVP launched two major armed uprisings. The first came in 1971 against the government of Prime Minister Sirimavo Bandaranaike. Young rebels attacked police stations across the island before the revolt was crushed, with thousands killed in the suppression. After Wijeweera was released from prison, the JVP briefly entered democratic politics in the late 1970s.

The second and far deadlier uprising ran from 1987 to 1989. It was partly fuelled by Sinhala nationalist anger at the Indo-Sri Lanka Accord, which brought the Indian Peace Keeping Force onto the island. This period saw extraordinary brutality on both sides, with the insurgency peaking in 1988 and, at its height, bodies discovered on the streets daily. The state’s counter-insurgency was ruthless, and the movement’s senior leadership, including Wijeweera himself, was killed in 1989. Tens of thousands died.

The JVP saga demonstrates that radicalism in Sri Lanka had multiple sources. While Tamil militancy grew from ethnic exclusion, Sinhala militancy grew from economic marginalisation and elite domination. Both reflected a political system that failed to give the disaffected a genuine stake.

Islamic radicalisation and post-war nationalism

The end of the civil war in 2009 did not bring lasting peace. Instead, a triumphant wave of Sinhala-Buddhist nationalism turned its attention to a new target: the Muslim minority. With the Tamil “threat” defeated, hardline groups such as the Bodu Bala Sena (Buddhist Power Force) were allowed to incite violence against Muslims with relative impunity.

Between 2014 and 2018, a series of anti-Muslim riots swept districts including Aluthgama, Digana, and Ampara. Mosques, homes, and Muslim-owned businesses were attacked, and disinformation campaigns spread baseless rumours about the community. This sustained pressure deepened the alienation felt by many young Muslims.

The Easter Sunday bombings

This combustible environment formed the backdrop to the country’s worst-ever terror attack. On 21 April 2019, nine bombers inspired by Islamic State ideology targeted churches and luxury hotels in Colombo, Batticaloa, and Negombo, killing over 250 people. The attacks were carried out by a local group, the National Thowheeth Jama’ath, led by the radical preacher Zahran Hashim.

Analysts point to a tragic feedback loop. Researchers note that Sinhalese Buddhist nationalism acted as a constant force fanning ethno-religious tensions, and the anti-Muslim violence it produced became one of the drivers pushing a small fringe of Muslim youth toward extremism. The bombings, in turn, were exploited by nationalist politicians to justify further discrimination, including the deeply resented policy of forced cremation of Muslim COVID-19 victims, deepening the cycle of grievance and reaction.

Elite dominance and the breaking point

Running through all of these conflicts is a persistent feature of Sri Lankan politics: domination by a small political elite. For decades, power rotated between two parties drawn largely from the Colombo establishment. In the 2000s, the Rajapaksa family consolidated control, with their governance increasingly defined by nepotism, authoritarianism, and financial mismanagement.

This elite model finally collapsed under economic strain. Severe policy missteps, including unsustainable borrowing, sweeping tax cuts, and an abrupt 2021 ban on chemical fertilisers, pushed the country into its worst economic crisis since independence. Sri Lanka defaulted on its external debt for the first time, and shortages of fuel, gas, and medicine brought daily life to a standstill.

Aragalaya and a new political opening

In 2022, public fury erupted into the Aragalaya movement, a mass protest whose Sinhala name means “the struggle.” Within months, the movement forced President Gotabaya Rajapaksa to flee the country and resign, while demanding a fundamental “system change.”

The political aftershock arrived in 2024. Voters elected Anura Kumara Dissanayake, leader of the National People’s Power coalition built around the JVP, on a platform of anti-corruption and clean government. In a striking historical irony, the party once known for two violent insurrections had reached the presidency through the ballot box, marking a dramatic repudiation of the political establishment that had governed since independence.

What the pattern reveals

Sri Lanka’s political journey illustrates a clear lesson in comparative politics. A formally democratic system is not enough to guarantee stability if it allows a permanent majority to monopolise power while excluding minorities. Tamil militancy, Sinhala insurrection, and Islamic extremism each grew from different soil, but all shared a common root: the failure of successive governments to build genuinely inclusive governance and to address socio-economic and political grievances before they hardened into armed conflict.

Whether the 2024 shift represents a true break from this cycle or merely a new chapter remains an open question. The grievances of war-affected Tamil communities, the anxieties of Muslims, and the economic pressures on Sinhalese youth have not disappeared. The durability of any democratic renewal will depend on whether the country can finally move beyond majoritarian habits toward shared political power.

What do you think? Does Sri Lanka’s experience suggest that majoritarian democracy is inherently unstable in multi-ethnic societies, or can institutional reforms like federalism and power-sharing genuinely overcome deep ethnic divides? And what lessons might other diverse democracies in South Asia draw from the way grievances in Sri Lanka were allowed to escalate into decades of violence?
