Afghan Independence Day, commemorates the Treaty of Rawalpindi in 1919, granting independence from Britain (Afghanistan)

Afghan Independence Day is celebrated as a national holiday in Afghanistan on 19 August to commemorate the Anglo-Afghan Treaty of 1919 and relinquishment from British Protected state status. The treaty granted a complete neutral relation between Afghanistan and Britain. Afghanistan had become a British protectorate after the Treaty of Gandamak was signed (1879) in the Second Anglo-Afghan War.

The Anglo-Afghan Treaty of 1919, also known as the Treaty of Rawalpindi, was a treaty which brought the Third Anglo-Afghan War to an end.
