Indonesia marked 80 years since its proclamation of independence this year amid renewed discussion over how the country’s founding era and its first president, Sukarno, are remembered in the Netherlands.

Relatives and supporters of Sukarno say the leader who declared independence in 1945 and guided the new republic in its early years has not received appropriate recognition in the Netherlands, where colonial rule endured in various forms for roughly 350 years. "Sukarno, my late father, was its founding father," said Kartika Soekarno in an interview, adding that Dutch schoolchildren and youth often know little of his role in Indonesia’s struggle for self-determination. She and others point to lingering symbols and policies that they say reflect an incomplete reckoning with colonial history.

Kartika and other family members have recounted accusations once leveled against Sukarno — including claims of collaboration and Communist sympathies — that they say obscured his role as a nationalist leader. They also cite postwar demands by Dutch authorities that the nascent Indonesian republic take on the debts of the former Netherlands East Indies, a figure they say would equal some 25 billion euros in today's terms. "The independence struggle after 350 years of Dutch colonialism was minimized," Kartika said, adding that perceptions of Sukarno were shaped by Cold War politics and Western anti-Communist campaigns.

Dutch political and royal figures have in recent years faced increased pressure to address the Netherlands' colonial past. The Dutch government has acknowledged excesses committed during the independence war and, in public statements, the Dutch monarch expressed regret for violence that occurred in the period following World War II. Dutch officials have also in some forums recognized 1945 as the year Indonesia proclaimed its independence, even though formal transfer of sovereignty took place later, in 1949.

Historians note the difference between the 1945 proclamation by Sukarno and Mohammad Hatta and the 1949 transfer of sovereignty after four years of diplomatic and armed struggle. Sukarno emerged as a central political figure in the immediate postwar era, serving as Indonesia’s first president until he was sidelined in the mid-1960s amid political upheaval. He died in 1970. The contested memory of that era includes disputes over wartime responsibility, the scale of violence, and the burdens placed on the new republic in the years after Dutch withdrawal.

Beyond public statements, families and activists point to more mundane markers of memory. Kartika noted that Amsterdam, for instance, names dozens of streets after Indonesian islands while comparatively few streets commemorate Indonesian individuals, a disparity she said reflected an incomplete public recognition of Indonesia’s leaders and their struggle. "The colonial system remains an unfinished revolution if Holland won’t recognize the father of our nation as our most significant freedom fighter," she said.

The debate over commemorations and historical recognition has played out in museums, academic forums and diplomatic engagements. Dutch institutions and scholars have increasingly opened archives and commissioned studies of the colonial period, while Indonesia has pressed for fuller acknowledgement of abuses and a more prominent place for Indonesian narratives in Dutch public history.

Cultural events timed to the 80th anniversary included performances by Indonesian gamelan troupes in cities outside Indonesia, underlining efforts by the diaspora and cultural institutions to bring the country’s history and traditions to international audiences. Such performances accompany public discussions in both countries about how best to remember the late colonial era and its aftermath.

Scholars caution that memory politics are shaped by both historical fact and contemporary priorities. The Cold War context that followed Indonesia’s 1945 proclamation influenced how Western governments and media portrayed Sukarno and the new republic, particularly as the United States and its allies sought to limit Communist influence in Asia. Those geopolitical dynamics shaped diplomatic recognition, aid, and narratives that have persisted into later decades.

The debate over Sukarno’s recognition in the Netherlands reflects broader questions about how former colonial powers confront uncomfortable chapters in their pasts. Dutch and Indonesian officials have held talks in recent years about history, restitution and symbolic reconciliation, but activists and descendants of independence-era figures say more concrete steps are needed to acknowledge suffering, settle outstanding historical claims and give fuller public attention to the people who led independence movements.

As Indonesia marks the 80th anniversary of its proclamation, the conversation about memory and recognition remains active. Family members and advocates say that while formal acknowledgements by Dutch authorities represent progress, they want more sustained institutional and cultural recognition of Sukarno’s role and of Indonesia’s struggle for sovereignty. Dutch leaders say the country is engaging with its colonial history through research, public education and diplomatic channels, though many observers argue that the process will take years and continued public pressure to reach widely accepted outcomes.

The anniversary has prompted new discussions in both nations about how to balance historical accuracy, symbolic gestures and the pursuit of justice for past wrongs. Those conversations are likely to continue as historians, diplomats and civil society groups press for clarity about the past and ways to commemorate it that respect multiple perspectives and experiences.
