Collaborators Act 1972  The Collaborators Act was a law enacted in 1972 by the government of Bangladesh to try those who did not side with the nationalist cause in the Bangladesh Liberation War, or politically opposed the liberation war or willingly cooperated with the Pakistan Army or committed criminal acts. This law is referred as the Bangladesh Collaborators (Special Tribunal) Order 1972, commonly known as Collaborators Act, 1972. About 2,884 cases were filed under this law until October 1973. Of the accused, 752 were given punishment. Later on 31 October 1975, the Collaborators Act was dismissed due to several reasons and irregularities found in the law. The law was amended three times. The Act, was designed to facilitate arrest and trial of accomplices as well as of local perpetrators of the genocide remained in place. What happened in Bangladesh between 25 March and 16 December 1971 epitomized the spirit of the human will as well as man's unlimited capacity to be brutal towards fellow men. Rarely in the history of mankind have a people displayed so much heroism and suffered so much pain within the space of so short a time as the people of Bangladesh did. During this war some Bengali civilians took the side of Pakistani Army of occupation. They collaborated the army to occupy the whole Bangladesh and supported the atrocities committed by them. The members of Pakistan Muslim League, Jamaat-e-Islami, Nizam-e-Islam joined the Peace Committee, which was actually formed to support the atrocities. A dummy cabinet was formed under Nurul Amin in which Abul Kashem, Nawajesh Ahmed, AKM Yousuf, Abbas Ali Khan, Maolana Ishak joined. Obaydullah Mazumder, an Awami League leader also joined in the cabinet. After liberation 46 MNAs from Awami League was denounced or relegated from the party. On the other hand, under the supervision of Pakistani Army another force named Rajakar was formed to replace the Ansar. Jamaat-e-Islami leader AKM Yousuf, with 96 members of Jamaat-e-Islami started a training camp in Khulna Ansar and VDP camp to fight against the freedom fighters. Most of the Rajakar personnel were the members of Jamaat-e-Islami  Al-Shams and Al-Badr was also formed in order to counter the guerrilla activities of the Mukti Bahini which grew increasingly organised and militarily successful during the second half of 1971. All three groups operated under Pakistani command. On this regard, Sheikh Mujibur Rahman on his repatriation in Bangladesh on 10 January 1972, declared to try the collaborators along with the Pakistani Army who committed genocide and atrocities.
