Emirate of Afghanistan 1919
Under Abdur Rahman's grandson Amanullah Khan, who ruled from 1919 to 1929, British involvement ended in Afghan external affairs with the Treaty of Rawalpindi, in which Afghanistan's Independence was recognised. Amanullah also initiated a series of ambitious efforts at social and political modernisation. The flag design was modified in 1919 by adding rays emanating from the seal in the form of an octogram.
