{{main|Russo-Persian War (1722–1723)}}
In June 1722, [[Peter the Great]], the then [[tsar]] of the neighbouring [[Russian Empire]], declared war on Safavid Iran in an attempt to expand Russian influence in the [[Caspian Sea|Caspian]] and [[Caucasus]] regions and to prevent its rival, [[Ottoman Empire]], from territorial gains in the region at the expense of declining Safavid Iran.

The Russian victory ratified for Safavid Irans' cession of their territories in the [[North Caucasus|Northern]], [[Southern Caucasus]] and contemporary mainland Northern Iran, comprising the cities of [[Derbent]] (southern [[Dagestan]]) and [[Baku]] and their nearby surrounding lands, as well as the provinces of [[Gilan province|Gilan]], [[Shirvan]], [[Mazandaran province|Mazandaran]], and [[Astrabad]] to Russia per the [[Treaty of Saint Petersburg (1723)]].<ref>William Bayne Fisher, P.

Tahmasp also eventually gained the recognition of both the [[Ottoman Empire]] and [[Russia]], each worried about the other gaining too much influence in Iran.{{vague|date=July 2015}}

By 1729, Tahmasp had control of most of the country. Quickly after his [[Tahmasp's campaign of 1731|foolhardy Ottoman campaign of 1731]], he was deposed by the future [[Nader Shah]] in 1732 in favor of his son, [[Abbas III]]; both were murdered at [[Sabzevar]] in 1740 by Nader Shah's eldest son [[Reza-qoli Mirza]].
