An edited version of this opinion piece was republished on the South China Morning Post portal platform here, under the title of “Malaysia’s Mahathir Mohamad: a 100-year mixed legacy”, on 20 July 2025.
To live a long political life in Malaysia is not unusual; to have a century’s longevity and the lengthiest career guarantees its two-time former premier ‘Dr M’ a unique place in the history books.
Mahathir Mohamad, the spry two-time prime minister of Malaysia, turns 100 today. Visionary but detail-oriented, charismatic yet divisive, Mahathir has profoundly shaped the country’s politics, economy, and society over the past six decades.
Mahathir’s incursion into electoral politics was a milestone. In 1964, he first ran for parliament for the United Malays National Organisation (UMNO) in Kedah. In contrast to UMNO’s urbane first-generation leaders, Mahathir came from a rural background and articulated a more ethnically focused vision for the country than was then the norm.
Following a brief period in the political wilderness due to his disagreements with Malaysia’s first prime minister (PM), Tunku Abdul Rahman, Mahathir rejoined UMNO in the wake of the May 1969 racial unrest. His rhetoric and worldview fit in with Malaysia’s conscious pivot towards addressing wealth disparities between different ethnic groups.
Becoming PM in 1981, Mahathir led the country for an unprecedented 22-year term. During this period, his economic stewardship was, at the macro level, laudable. Mahathir was committed to balanced budgets, having a relatively open economy, investing in infrastructure, and attracting foreign direct investment. The result was an average annual growth rate of between six and seven per cent per year.
Mahathir was determined to make Malaysia a modern, self-sufficient, and “fully developed” nation by 2020. His quest was further enabled by Malaysia’s deep reservoirs of petroleum, whose rents burgeoned in the 1980s. Mahathir’s ensuing infrastructure drive transformed the country’s landscape with landmarks such as the Kuala Lumpur International Airport, the Petronas Twin Towers, and the questionable Multimedia Super-Corridor.
As PM, Mahathir focused on revitalising the bureaucracy. Leading by example, he prioritised excellence and professionalism, introducing name badges for civil servants, time-keeping, and a Client’s Charter to promote accountability. In addition, the Public Complaints Bureau and Anti-Corruption Agency were strengthened during his tenure.
At the international level, Mahathir was a supporter of the Non-Aligned Movement. He espoused moderate Islam, cementing Malaysia’s reputation as one with whom the West could engage. He also promoted a “Look East Policy”, aimed at learning from the successes of Japan and South Korea, and deepened Malaysia’s engagement with China.
At his best, Mahathir articulated a vision based on pride and nationalism, the pursuit of economic growth, and technological ambition that unified Malaysia. Although the country has yet to attain high-income status even now, Mahathir’s economic stewardship during his first administration underpins the residual goodwill he enjoys today, recent political events notwithstanding.
Beyond economic management, increasing state capacity, and mobilising Malaysians around a specific vision, however, Mahathir’s legacy in many areas is mixed. In some cases, middling results were caused by his seeking to maintain rhetorical ambiguity, and in others, his formidable personality played a role.
Perhaps the best way to sum up Mahathir is as someone with great ambition, high standards, and an exceptional work ethic, but who also has an uncompromising nature that undermined many initiatives.
As to the first factor, Mahathir modelled Malaysia as a moderate Muslim country but undercut this narrative to outflank UMNO’s existential rival, the Islamic party, Partai Islam SeMalaysia (PAS). In response, he co-opted Anwar Ibrahim, then leader of the Malaysian Islamic Youth Movement into UMNO. Once in government, Anwar promoted increasing Islamisation, including boosting religious education in schools. Mahathir’s consequent pronouncement in 2001 that Malaysia is an “Islamic State” provided a rhetorical opening to his opponents.
Throughout his career, Mahathir supported ethnic-based affirmative action, while seeking to galvanise Malays by accusing them of being lazy, lacking a long-term perspective, and ungrateful. Operationally, he sought to build on Malaysia’s affirmative action programmes to uplift Malay and indigenous communities by hand-picking businessmen to receive preferential concessions for water provision, rail, airlines, and auto production. While the goal was to create genuine corporate leaders, the reliance on non-market mechanisms made many of these debt-fuelled corporate empires untenable, leading to massive corporate bailouts.
As for his personality, Mahathir’s ability to chart clear directions made him intransigent. This undermined leadership succession, as seen by Mahathir’s diatribes against subsequent prime ministers, including but not limited to Abdullah Badawi, Najib Razak, and his protégé-turned-nemesis, current PM Anwar Ibrahim.
This inflexibility impacted the country’s institutions. In UMNO, Mahathir centralised power in the office of party president. In government, he weakened checks on the executive by maintaining tight control of the media, constraining the country’s royalty, and eroding the institutions of the judiciary and Parliament. The budget, size and reach of the Prime Minister’s Office expanded rapidly under his tenure, even absorbing parliament’s own civil service. The role of state governments was also curtailed through enhanced budgetary controls and constitutional amendments to reduce their scope.
Mahathir had an autocratic side. In 1987, with the questionable rationale of preventing racial riots, he orchestrated a crackdown on political activists, opposition politicians, and students, detaining them without trial under the Internal Security Act. In 1998, Mahathir sacked his deputy, Anwar Ibrahim, on the alleged grounds of sexual misconduct and corruption, igniting a national Reformasimovement in response.
After 21 years — and scenting a potential electoral defeat for UMNO and its coalition, Barisan Nasional — Mahathir voluntarily stepped down in 2003. His second stint as prime minister and his subsequent downfall are a perfect case study of the mixed record of his legacy.
The effects of Mahathir’s concentration of power in the PM’s position were made manifest under Najib Razak’s tenure. To contain the effects of the multi-billion-dollar exposé of the national investment fund, 1MDB, the latter used the awesome power of the prime minister’s office to remain in power.
To unseat Najib, Mahathir exited UMNO to set up a new party, Bersatu. He then partnered with former foes including Anwar Ibrahim’s Pakatan Harapan (PH) coalition. Drawing on his achievements and oratory, Mahathir was instrumental in appealing to Malay-majority constituencies, allowing PH to cobble together a parliamentary majority and seize power.
In office for the second time, Mahathir had a unique opportunity to fix the structural excesses of the structures he created. However, Mahathir’s distaste for Anwar eventually overcame his desire for continuity, as his constant toying with the handing over of power without doing so became untenable.
Had he ceded leadership to a named successor, Mahathir would have been able to credibly claim he restored Malaysia’s democracy. However, caught between giving way to Anwar or allying with Najib Razak and his faction in UMNO, Mahathir sought to lead a “unity government” that brought together all parliamentary factions. When this was not forthcoming, Mahathir resigned. This led to one of the most turbulent periods in Malaysia’s political history, with an unprecedented four governments in three years.
Since the end of his second prime ministership, Mahathir has shifted from being a mainstream politician to one on the fringe. Gone are his association with UMNO and Bersatu. In the 2022 general election, he suffered an electoral defeat — not even garnering enough votes to keep his deposit.
Perhaps the best way to sum up Mahathir is as someone with great ambition, high standards, and an exceptional work ethic, but who also has an uncompromising nature that undermined many initiatives. This depiction explains his longevity, physical and political. That no prime minister who has followed him can live up to his expectations and that Malaysia has yet to attain high-income status fuel this centenarian’s angst and drive.
