The term "G30S" refers to the "30 September Movement" in Indonesia, which was a failed coup attempt that occurred in 1965. This event involved a group of military officers who sought to overthrow the government of President Sukarno. The coup resulted in the assassination of several high-ranking military officials and led to widespread violence and political upheaval. In the aftermath of the G30S coup, a significant anti-communist purge took place, resulting in the deaths of hundreds of thousands of people. The event ultimately paved the way for Suharto to rise to power, marking the beginning of a new era in Indonesian politics known as the New Order.
