Since the 1870s, various pieces of colonial legislation in India during British rule were collectively called the Criminal Tribes Act (CTA), which criminalized entire communities by designating them as habitual criminals. Under these acts, ethnic or social communities in India were defined as "addicted to the systematic commission of non-bailable offences" such as thefts, and were registered by the government. Adult males of the groups were forced to report weekly to local police, and had restrictions on their movement imposed. The first CTA, the Criminal Tribes Act 1871, applied mostly in North India, before it was extended to the Bengal Presidency and other areas in 1876, and updated to the Criminal Tribes Act 1911, which included the Madras Presidency. The Act went through several amendments in the next decade, and, finally, the Criminal Tribes Act 1924 incorporated all of them. At the time of Indian independence in 1947, thirteen million people in 127 communities faced search and arrest if any member of the group was found outside the prescribed area. The Act was repealed in August 1949 and former "criminal tribes" were denotified in 1952, when the Act was replaced with the Habitual Offenders Act 1952. In 1961 state governments started releasing lists of such tribes. Today, there are 313 Nomadic Tribes and 198 Denotified Tribes of India, yet the legacy of the past continues to affect the majority of 60 million people belonging to these tribes, as their historical associations have meant continued alienation and stereotyping by the police and the media as well as economic hardships. Many of them are still described as "Ex-Criminal Tribes". From Wikipedia
