Savtegin (d. 1084) was a prominent emir of the early Seljuk Empire, during the reigns of Tughril I, Alp Arslan, and Malik-Shah I.^[1] His full name in Arabic, as given by Münejjim Bāshī Ahmad Effendi, was 'Imād ad-Dawlah Sarhang Sāw Takīn.^[2] He first appears in sources during the reign of Tughril I, when he was sent as an ambassador when rumors arose that Ibrahim Yinal would rebel.^[1] He later took part in the campaign against Arslan Besasîrî, a Turkic commander under the Buyids who had captured the Abbasid caliph al-Qa'im.^[1] Arslan Besasîrî was killed in battle on 18 January 1060.^[1] Later, in April–May 1061, Savtegin was part of the delegation sent to Baghdad to negotiate a marriage between Tughril and al-Qa'im's daughter Sayyida (Arslan Khatun, daughter of Tughril's brother Chaghri Beg, and the vizier Amid al-Mulk Kondori were also part of this delegation).^[1]

After Tughril's death in 1063, the vizier Amid al-Mulk installed Chaghri Beg's son Sulayman on the throne, but Alp Arslan and Qutalmish each also claimed the throne.^[1] Savtegin backed Alp Arslan, who defeated Kutalmish and became sole ruler in January 1064.^[1] After this point, Savtegin is given the title "emir" in sources and is described as one of the leading men in the Seljuk state.^[1] Later, Savtegin was part of a delegation sent to meet with the Byzantine emperor Romanos IV Diogenes in the lead-up to the Battle of Manzikert in 1071.^[1] Savtegin also participated in the battle at Manzikert.^[1]

After Alp Arslan's death in 1072, his son Malik-Shah succeeded him but was contested by his uncle Qavurt.^[1] Savtegin was the leading commander on Malik-Shah's side, which ended up victorious.^[1] Savtegin later participated in campaigns under Malik-Shah against the Karakhanids, in Ganja and Arran, and in Georgia.^[1] Malik-Shah appointed him (or someone else with the same name) governor of Termez when he captured the city in 1073.^[2] Malik-Shah later appointed Savtegin amir al-hajj in 476 AH (1083-84 CE).^[1] He was received by the Abbasid caliph al-Muqtadi in Baghdad on 17 April 1084, who honored him by dressing him in a hil'at.^[1]

Not long after, though, Savtegin came down with tuberculosis.^[1] He hurried back to Isfahan, where he died on a Friday in September or October 1084.^[1] He left behind a massive fortune: two million dinars, 15,000 items of clothing (including 9,000 made of Greek silk), 5,000 horses, 1,000 camels, and 30,000 sheep.^[1] This is not including land, weapons, or other possessions.^[1] At some point, Savtegin also founded a ribat in Hakister, where he was born.^[1]
