After independence, Malaysia and Singapore head authorization governments in which
they were governed by a single party that held power for several decades. In Malaysia, the United Malays National Organization (UMNO) dominated politics under the leadership of Prime Minister Tunku Abdul Rahman. In Singapore, the People's Action Party (PAP) led by Lee Kuan Yew held onto power after gaining independence from Malaysia.
Both countries implemented policies that focused on economic development, industrialization, and social stability. However, there were also challenges such as ethnic tensions and political unrest. Malaysia experienced race riots in 1969 which led to the implementation of policies favoring the Malay majority, while Singapore faced threats of communism and separatism.
Over time, both countries transitioned towards more democratic systems of governance with regular elections and greater political participation. Malaysia continues to be governed by a coalition of parties, with UMNO playing a significant role, while Singapore has maintained one-party rule under the PAP.
Overall, the authoritarian governments in Malaysia and Singapore were instrumental in shaping the countries' development and have been credited with laying the foundation for their economic success and political stability.
