On the first of June 1945, more than two months before Indonesia declared independence, Sukarno stood before the committee charged with preparing that independence and offered five principles he argued could hold together a nation of more than a thousand ethnic groups, hundreds of languages, and every major world religion within one set of borders drawn by a departing colonial power. He called the principles Pancasila: belief in one God, just and civilised humanity, the unity of Indonesia, democracy guided by deliberation and consensus, and social justice for all Indonesians. Eight decades later, Pancasila remains Indonesia's official state philosophy, and its distinctive achievement has been holding a position that satisfies almost no one entirely: neither a secular state nor an Islamic one, neither pure majority rule nor authoritarian command.
The philosophy's legitimacy claim rests on consensus rather than a simple majority vote, expressed through musyawarah, deliberation among representatives, seeking mufakat, or agreement, on behalf of a national unity Sukarno held to be prior to the interest of any single religion, region or ideology. That consensus based authority found its sharpest test in the debate the founding committee itself had over the first principle. An earlier draft, the Jakarta Charter, would have required Indonesian Muslims specifically to follow Islamic law; the final version adopted instead named belief in one God generally, satisfying neither secular nationalists who wanted religion excluded from the state altogether nor Islamist delegates who wanted sharia named explicitly, a genuine compromise built into the philosophy's very first principle.
That same principle carried a second, harder edge once Pancasila moved from founding document to governing tool. By naming belief in one God as foundational, Pancasila built in an explicit rejection of atheism, and after 1965, when an attempted coup was blamed on the Indonesian Communist Party, that rejection became doctrine enforced with lethal seriousness: the party was banned, hundreds of thousands of suspected communists and sympathizers were killed in the violence that followed, and anti-communism became, for decades afterward, part of Pancasila's practical enforcement rather than merely its theoretical implication. The same five principles that were designed to hold a diverse nation together on paper have also, at the moments of greatest political stress, been mobilized to draw a hard boundary around who counts as a legitimate part of that nation at all.
