Q. When was the Santhal Parganas Settlement Regulation Act passed?
Answer: 1872
Notes: The Santhal Parganas Settlement Regulation Act was enacted in 1872. It was passed by the British government to regulate settlement operations in the Santhal Parganas region. The act followed the Santhal Insurrection of 1855-57 and introduced a special administrative system. It removed the application of general laws in the tribal-dominated area to maintain peace and governance. This act served as a model for similar tribal area regulations in India.
