The Murderous Outrages Regulation was enacted in British India (which included modern Pakistan) in 1867 to give the government additional powers to prosecute serious crimes such as murder. It was re-enacted in 1873 with minor modifications, and again in 1877 as the "Ghazi Act" for its use in the Pashtun-inhabited frontier districts.[4][failed verification] The 1893 unilateral demarcation of the Durand Line by the British as the border between Afghanistan and India, which divided Pashtun tribes across the border, caused further animosity among the Pashtun.[5]
