The Indian Penal Code (IPC) is the main criminal code of India. It is a comprehensive code intended to cover all substantive aspects of criminal law. The code was drafted in 1860 on the recommendations of first law commission of India established in 1834 under the Government of India Act 1833 under the Chairmanship of Thomas Babington Macaulay. It came into force in British India during the early British Raj period in 1862. However, it did not apply automatically in the Princely states, which had their own courts and legal systems until the 1940s. The Code has since been amended several times and is now supplemented by other criminal provisions. Based on IPC, Jammu and Kashmir has enacted a separate code known as Ranbir Penal Code (RPC).
