against the British, the Afghans were more interested in regaining lands across the Amu Darya lost to Russia in the nineteenth century. Afghan attempts to regain the oases of Merv and Panjdeh were easily subdued by the Soviet Red Army. In May 1921, the Afghans and the Soviets signed a Treaty of Friendship, Afghanistan's first international agreement since gaining full independence in 1919. The Soviets provided Amanullah with aid in the form of cash, technology and military equipment. Despite this, Amanullah grew increasingly disillusioned with the Soviets, especially as he witnessed the widening oppression of his fellow Muslims across the border. Anglo-Afghan relations soured over British fear of an Afghan-Soviet friendship, especially with the introduction of a few Soviet planes into Afghanistan. British unease increased when Amanullah maintained contacts with Indian nationalists and gave them asylum in Kabul, and also when he sought to stir up unrest among the Pashtun tribes across the border. The British responded by refusing to address Amanullah as "Your Majesty," and imposing restrictions on the transit of goods through India.

Mahmud Tarzi, Amanullah's father-in-law and Foreign Minister, encouraged the monarch's interest in social and political reform but urged that it be gradually built upon the basis of a strong central government, as had occurred in Turkey under Kemal Atatürk. Socially, Amanullah enjoyed many of Mahmud Tarzi's thoughts at the time, such as giving women more rights and allowing freedom of press through publishing.

His wife, Queen Soraya Tarzi, became the face of Amanullah Khan's reforms in regard to women. Amānullāh's reforms touched on many areas of Afghan life.

Although he came to power with army support, Amanullah alienated many army personnel by reducing both their pay and size of the forces and by altering recruiting patterns to prevent tribal leaders from controlling who joined the service. Amanullah's Turkish advisers suggested the king retire the older officers, men who were set in their ways and might resist the formation of a more professional army. Amanullah's minister of
