IPC stands for Indian Penal Code. Enacted in 1860, the IPC was the primary substantive criminal law of India — the law that defined what constitutes a crime and what punishment follows. For over 160 years, it was the bedrock of India’s criminal justice system.
Critical Update for 2026: The IPC has been replaced by the Bharatiya Nyaya Sanhita, 2023 (BNS), which came into force on July 1, 2024. While the IPC no longer applies to new offences, it continues to govern millions of cases registered before July 1, 2024.
Understanding the IPC remains essential for law students, advocates, and judicial officers — both for ongoing IPC cases and because the BNS closely mirrors much of the IPC’s structure.
History of IPC
The Indian Penal Code has a fascinating colonial history. The First Law Commission of India, established in 1834 under the Charter Act of 1833, was chaired by Lord Thomas Babington Macaulay. He drafted the IPC between 1834 and 1837, based primarily on English criminal law but adapted to Indian conditions.
The draft was submitted in 1837 but faced various objections and revisions. It was finally enacted in 1860 — just three years after the Revolt of 1857 — and came into force on January 1, 1862.
For 162 years, the IPC served as India’s criminal law backbone — covering everything from petty theft to murder, from defamation to sedition.
