The Afghan peace delegation stayed there before signing the Treaty of Rawalpindi which formally ended the 3rd Afghan War on 8 August 1919. The treaty finally gave the Afghans the right to conduct their own foreign affairs as a fully independent state. For the British, the Durand Line, long a contentious issue between the two nations, was reaffirmed as the political boundary separating Afghanistan from the North-West Frontier. The Afghans also agreed to stop interfering with the tribes on the British side of the line.
