The Waziristan campaign 1936–1939 comprised a number of operations conducted in Waziristan by the British Indian Army against the fiercely independent tribesmen that inhabited this region. These operations were conducted in 1936–1939, when operations were undertaken against followers of the Pashtun nationalist Mirzali Khan, also known by the British as the "Faqir of Ipi", a religious and political agitator who was spreading anti-British sentiment in the region and undermining the prestige of the Indian government in Waziristan at the time.
