Criminal Tribes Act
The term Criminal Tribes Act (CTA) applies to various successive pieces of legislation enforced in India during British rule; the first enacted in 1871 as the Criminal Tribes Act, 1871 applied mostly in North India. The Act was extended to Bengal Presidency and other areas in 1876, and, finally, with the Criminal Tribes Act, 1911, it was extended to Madras Presidency as well. The Act went through several amendments in the next decade and, finally, the Criminal Tribes Act, 1924 incorporated all of them.
The 1871 Act came into force, with the assent of the Governor-General of India on 12 October 1871. Under the act, ethnic or social communities in India which were defined as "addicted to the systematic commission of non-bailable offences" such as thefts, were systematically registered by the government. Since they were described as 'habitually criminal', restrictions on their movements were also imposed; adult male members of such groups were forced to report weekly to the local police.
