Tahmasp II
The campaigns of Nader Shah, or the Naderian Wars, were a series of conflicts fought in the early to mid-eighteenth century throughout Central Eurasia primarily by the Iranian conqueror Nader Shah. His campaigns originated from the overthrow of the Iranian Safavid dynasty by the Hotaki Afghans. In the ensuing collapse and fragmentation of the empire after the capture of the Iranian capital of Isfahan by the Afghans, a claimant to the Safavid throne, Tahmasp II, accepted Nader (who was no more than a petty warlord in Khorasan) into his service. After having subdued north-west Iran as well as neutralising the Abdali Afghans to the east as well as turning Tahmasp II into a vassal, Nader marched against the Hotaki Afghans in occupation of the rest of the country. In a series of incredible victories the Afghans were decimated and Tahmasp II returned to the throne as a restored Safavid monarch.
