Socialism was first introduced in Indonesia in the 1920s by the Indonesian Communist Party (PKI).
During Soekarno's reign in the 1950s and 1960s, Indonesia adopted socialist ideology as a basis for national development.
At that time, economic sectors such as oil, gas, and mining nationalization were taken over by the state.
The concept of socialization is also applied to the plantation and industrial sectors, with the aim of strengthening the national economy and reducing social inequality.
However, during the New Order era in the 1960s to the 1990s, socialism became an ideology that was marginalized and even suppressed by the government.
Only in the reform era in the late 1990s, socialism again became the topic discussed among academics and social activists.
One of the famous Indonesian socialist figures is Pramoedya Ananta Toer, an active writer and intellectual in the Soekarno and New Order era.
At present, the Indonesian Labor Party (PBI) is a political party in Indonesia that carries a socialist and Marxist ideology.
In Indonesia, there is still debate and controversy regarding whether socialism can be applied effectively in the context of Indonesia which is rich in social, cultural, and religious diversity.
Nevertheless, there are many social movements and communities that struggle to create a more just and equitable society in Indonesia by carrying out socialist values.
