The Safavid Empire of Iran is defeated by an army from Afghanistan at the Battle of Gulnabad, pushing Iran into anarchy.
The Battle of Gulnabad (Sunday, March 8, 1722) was fought between the military forces from Hotaki Dynasty and the army of the Safavid Empire. It further cemented the eventual fall of the Safavid dynasty, which had been declining for decades.
Safavid Iran or Safavid Persia (), also referred to as the Safavid Empire, was one of the greatest Iranian empires after the 7th-century Muslim conquest of Persia, ruled from 1501 to 1736 by the Safavid dynasty. It is often considered the beginning of modern Iranian history, as well as one of the gunpowder empires. The Safavid shahs established the Twelver school of Shia Islam as the official religion of the empire, marking one of the most important turning points in Muslim history.
The Safavid dynasty had its origin in the Safavid order of Sufism, which was established in the city of Ardabil in the Azerbaijan region. It was an Iranian dynasty of Kurdish origin but during their rule they intermarried with Turkoman, Georgian, Circassian, and Pontic Greek dignitaries, nevertheless they were Turkish-speaking and Turkified. From their base in Ardabil, the Safavids established control over parts of Greater Iran and reasserted the Iranian identity of the region, thus becoming the first native dynasty since the Sasanian Empire to establish a national state officially known as Iran.The Safavids ruled from 1501 to 1722 (experiencing a brief restoration from 1729 to 1736) and, at their height, they controlled all of what is now Iran, Republic of Azerbaijan, Bahrain, Armenia, eastern Georgia, parts of the North Caucasus including Russia, Iraq, Kuwait, and Afghanistan, as well as parts of Turkey, Syria, Pakistan, Turkmenistan and Uzbekistan.
Despite their demise in 1736, the legacy that they left behind was the revival of Iran as an economic stronghold between East and West, the establishment of an efficient state and bureaucracy based upon "checks and balances", their architectural innovations and their patronage for fine arts. The Safavids have also left their mark down to the present era by spreading Twelver Islam in Iran, as well as major parts of the Caucasus, Anatolia, the Persian Gulf, and Mesopotamia.
