While the older nationalist leadership group, including Sukarno and Hatta, were reluctant, younger members of the new elite, the 'youth' (Indonesian: "pemuda"), believed they had a duty to push for revolution. A group associated with Menteng 31 kidnapped both Sukarno and Hatta and forced them to agree to declaring Indonesian independence. On 17 August 1945, two days after the surrender, Sukarno and Hatta declared independence at Sukarno's house in Jakarta. Indonesian staff briefly seized Jakarta radio from their Japanese supervisors and broadcast the news of the declaration across Java.
