Wazir Mohammad Gul Khan Momand was born in Andrabayo, Kabul Province to a Mohmand Pashtun family and his forefathers were originally from Nangarhar.
His great grandfather, Abdul Kareem, also served in the Afghan Army during the reign of King Dost Mohammad Khan.
In October 1929, the bandits were completely defeated and the official government of Afghanistan was restored under the King Mohammed Nadir Shah.
The family of King Mohammed Nadir Shah had enormous respect for Mohammad Gul Khan and considered him as their sixth brother.
From 1930 to 1939, Mohammad Gul Khan was appointed as the Minister of Interior of Afghanistan in the Cabinet of King Mohammed Nadir Shah.
The stories of Mohammad Gul Khan's service to Afghanistan is common talking points in Afghan households.
Mohammad Gul Khan was a strong advocate of Pushtun Human Rights even across the Durand line which includes Khyber-Pakhtunkhwa, Federally Administered Tribal Areas (FATA) and part of Balochistan.
He balanced the domination of Durrani from Kandahar by introducing many more eastern Pashtuns to the area (especially as landowners between Aqcha and Balkh), and he appears to have dealt fairly with petitions against the Nazarzai brought by Uzbeks and Aymaks from throughout the Saripul region and its hinterland."
His funeral was attended by the then prime minister of Afghanistan, Sardar Mohammad Daoud Khan, and King Zahir Shah.
