Increasingly vocal against non-Lekra members, the group rallied against the Manifes Kebudayaan (Cultural Manifesto), eventually leading to President Sukarno banning it with some hesitations.
[1] Beginning in 1962, Lekra became increasingly vocal against those it considered to be against the people's movement, including author and religious leader Haji Abdul Malik Karim Amrullah and documentarian HB Jassin.
After the failed 30 September Movement coup, popularly believed to have been promoted by the Communist Party, and the mass killings that followed, Sukarno's replacement Suharto and his New Order government banned Lekra together with the other communist-associated organizations.
Bodden adds that critic Ikranegara dismissed Lekra's entire body of work in his history of Indonesian theatre, instead focusing on their "anti-humanism".
