The League was founded by Lieutenant Ali Abdullatif. It advocated for "Unity of the Nile Valley," calling for Sudanese independence and unity with Egypt, and pledging allegiance to King Fuad.
First lieutenant Abdul Fadil Almaz led the group's insurrection of the military training academy, which ended in their defeat and the Almaz's death after the British army blew up the military hospital where he was garrisoned. It has been suggested that this defeat was partially the result of the Egyptian garrison in Khartoum North not supporting the insurrection with artillery as was previously promised.
