Comrade Sultan Ahmed Khan Tarin or simply Comrade Sultan Ahmed (a.k.a. name sometimes also given as 'Sultan Muhammad Khan') (1901-1970) was an early Communist leader from the North-West Frontier Province of British India.
Comrade Tarin was born in 1901 to a rural family of the Tarin/Tareen tribe settled in Rehana village, Haripur District, Hazara, NWFP. His father was Abdul Jabbar Khan, a village Lambardar and government revenue collector and he tried to give Tarin as good an education as he could afford. On finishing his college studies, Tarin was not interested like most young men of the time in either seeking a government job or enrolling in the British Indian Army. Instead, he was inspired by the Khilafat Movement and sought to go to Kabul, Afghanistan, and try from there to reach Turkey, and strive in the cause of the Islamic Ottoman Caliphate.
In 1920, Tarin and some of his young companions managed to make it to Kabul and there, they found that the Khilafat Movement was quite moribund and that most so-called 'Muhajireen' (immigrants from India, in the cause of Islamic Jihad) were merely languishing in the Afghan capital.
At this time, Tarin met and was considerably impressed by some young Hindus from India, who were planning to go to join MN Roy in Moscow, USSR and he was converted to the dynamic Communist perspectives for change in the British Indian colony. He also joined these young men and went with them and eventually ended up joining MN Roy and his senior associates in Tashkent in the then Soviet Turkestan and was present at the founding of the Communist Party of India there, in October 1920.
