The origin of the rank of field marshal dates to the early Middle Ages, originally meaning the keeper of the king's horses (from old German Marh-scalc=horse-servant") from the time of the early Frankish kings.
Muhammad Ayub Khan (Urdu/Pashto: ???? ???? ???), GCMG, MBE, HJ, NPk, (May 14, 1907 – April 19, 1974) was a Field Marshal during the mid-1960s, and the President of Pakistan from 1958 to 1969. He became Pakistan's first native Commander in Chief in 1951, and was the youngest full-rank general and "SELF-APPOINTED" field marshal in Pakistan's military history. He was also the first Pakistani military general to seize power through a coup.
