The Inner Line Regulation, which established a legal boundary separating the tribal areas of present-day Arunachal Pradesh from the plains of British Assam, was enacted in which year?

💡 Solution & Explanation

The Bengal Eastern Frontier Regulation, commonly known as the Inner Line Regulation, was enacted by the British colonial administration in 1873 to protect British commercial interests in tea and rubber plantations and to regulate interactions with the hill tribes of the northeastern frontier. The year 1914 marks the Simla Convention where the McMahon Line was negotiated, and 1905 corresponds to the Partition of Bengal. The Inner Line continues to function today as a protective regulatory permit system for visitors entering Arunachal Pradesh.
