Thailand’s political landscape has been marked by chronic instability for nearly a century, characterized by frequent coups, judicial interventions, and a persistent tug-of-war between democratic aspirations and entrenched authoritarian elements.
This has resulted in a cycle of short-lived governments, suppressed reforms, and economic disruptions, with the country experiencing at least 13 successful military coups since the end of absolute monarchy in 1932. As of September 2025, the crisis shows no signs of abating, with recent events like the ousting of Prime Minister Paetongtarn Shinawatra underscoring the fragility of civilian rule. Below, I’ll outline the primary reasons for this ongoing turmoil, drawing from historical patterns, key rivalries, institutional flaws, and current triggers.
Historical Context: A Legacy of Coups and Constitutional Flux
Thailand’s politics have been unstable since the 1932 Siamese Revolution, which transitioned the country from absolute monarchy to a constitutional system. However, this shift did not end elite power struggles; instead, it initiated a pattern of military dominance. The nation has had 20 constitutions or charters, many imposed or abrogated following coups, reflecting deep-seated conflicts among old elites, bureaucrats, and military factions. Periods of semi-democracy (e.g., 1932–1973) were interrupted by authoritarian regimes, with notable upheavals including the 1973 student uprising against military rule, the violent 1976 coup, and more recent takeovers in 1991, 2006, and 2014. This history fosters a “vicious cycle” where civilian governments are routinely toppled by the military, preventing the consolidation of stable democracy.
Key Conflicts: Populism vs. the Establishment
At the heart of the crisis is a rivalry between populist movements and a conservative “establishment” comprising the military, monarchy, and judiciary. Populist leaders like Thaksin Shinawatra, who rose to power in 2001 with policies appealing to rural and working-class voters, challenged traditional elites by redistributing wealth and expanding social programs. This sparked backlash, leading to Thaksin’s ouster in a 2006 coup and the exile or removal of his allies, including his sister Yingluck in 2014. The divide manifests in factional protests, such as those by “Red Shirts” (pro-Thaksin) versus “Yellow Shirts” (anti-Thaksin royalists), exacerbating polarization.
The monarchy and military act as barriers to reform, using their influence to maintain status quo. The monarchy, protected by strict lèse-majesté laws (Section 112), opposes changes that could diminish its symbolic or practical power, while the military relies on coercive authority to back it. Progressive parties like Move Forward (dissolved in 2023) and its successor, the People’s Party, push for democratic reforms, including monarchy accountability, but face dissolution or bans for allegedly threatening the system. This dynamic pits electoral majorities against unelected guardians of “Thai values,” often framing populism as a threat to national unity.
An urban-rural divide further fuels tensions: Urban middle classes tend to oppose populists, viewing them as corrupt, while rural populations support them for tangible benefits like healthcare and subsidies. Corruption, estimated to cost billions annually, permeates both sides, eroding trust and providing pretexts for interventions.
Structural and Institutional Issues
The 2017 constitution, drafted under military rule after the 2014 coup, entrenches establishment power by creating an appointed Senate that influences key decisions, such as prime ministerial selections and constitutional amendments. This setup allows conservative forces to override popular votes, as seen in “secret deals” like the 2023 coalition between Pheu Thai and military-aligned parties, which sidelined the election-winning Move Forward. The judiciary, perceived as biased, frequently removes elected leaders on ethical or legal grounds while showing leniency to establishment figures. For instance, parties are dissolved for minor infractions, reinforcing authoritarianism over democracy.
Thailand is classified as a “flawed democracy” with low public trust, where high voter turnout contrasts with systemic barriers to genuine representation. Authoritarian tendencies deepen this, as the military-monarchy alliance uses legal tools to “polish off” populism, shifting the country toward hybrid autocracy rather than inclusive governance.
Recent Developments and Triggers
In 2025, the crisis intensified with Paetongtarn Shinawatra’s removal as PM on August 29 by the Constitutional Court over a leaked phone call with Cambodia’s Hun Sen, deemed an ethics violation. This followed her father Thaksin’s controversial return and brief detention, highlighting the Shinawatra family’s enduring role in the turmoil. The ruling Pheu Thai-led coalition faces collapse, with calls for new elections from the People’s Party, which seeks constitutional changes for greater democracy. Border tensions with Cambodia and economic woes, including $2.3 billion in foreign investor outflows, compound the instability. Analysts warn of potential military-backed caretakers or further judicial meddling if reforms threaten the establishment.
Implications for Stability
This perpetual crisis stifles economic growth, deters investment, and erodes faith in institutions. Without addressing the establishment’s veto power—through constitutional overhaul or reduced military influence—Thailand risks remaining trapped in authoritarian cycles, where elections occur but meaningful change is blocked. While tourists and daily life often remain unaffected by demonstrations or coups, the underlying fragility threatens long-term progress.
