The Five Founding Fathers of ASEAN

ASEAN was founded by five governments—and by five ministers who converted the end of regional confrontation into a compact promise of cooperation.

Why these five people

The title ‘Founding Fathers of ASEAN’ refers specifically to the five signatories of the ASEAN Declaration in Bangkok: Adam Malik for Indonesia, Tun Abdul Razak for Malaysia, Narciso Ramos for the Philippines, S. Rajaratnam for Singapore and Thanat Khoman for Thailand. Their biographies show how different national careers converged at one regional turning point.

01
From dispute to dialogue
The end of Indonesia–Malaysia Confrontation and efforts to repair relations created the diplomatic opening in which ASEAN could be negotiated.
02
Five national perspectives
A former independence activist, a deputy prime minister and three foreign ministers brought different state-building experiences to Bangkok.
03
A short, open declaration
The five articles established cooperation around development, education, culture, peace and stability while leaving membership open to the region.
04
A legacy larger than the founding five
Six later accessions expanded the institution from its original membership to all eleven sovereign states of Southeast Asia by 2025.
