With his new army, Abbas Mirza invaded Russia in 1826. While in the first year of the war Persia managed to regain almost all lost territories, reaching almost Georgia and Dagestan too, the Persian army ultimately proved no match for the significantly larger and equally capable Russian army. The following Treaty of Turkmenchay in 1828 crippled Persia through the ceding of much of Persia's northern territories and the payment of a colossal war indemnity. The scale of the damage done to Persia through the treaty was so severe that The Persian Army and state would not regain its former strength till the rise and creation of the Soviet Union and the latter's cancellation of the economic elements of the treaty as 'tsarist imperialistic policies'. After these periods of Russo-Persian Wars, Russian influence in Persia rose significantly too.
