Najafqolī Khan Ṣamṣām-al-Salṭana, an īlḵān of the Baḵtīārī tribe and prime minister of Iran after Moḥammad-ʿAlī Shah was deposed. The second son of Ḥosaynqolī Khan Īlḵānī, Najafqolī was born in 1270/1853-54 and was educated to the point of literacy while with the tribe. After his father was killed by Ẓell-al-Solṭān, the reigns of Baḵtīārī government fell into the hands of Najafqolī’s paternal uncles. When Ẓell-al-Solṭān was removed from the governorate of Isfahan in 1305/1887-88 and Najafqolī’s elder brother Esfandīār Khan was released from prison and made īlḵān, Najafqolī became his deputy (īlbegī). With his brother’s death in 1331/1913, Najafqolī assumed the office of īlḵān with the title Ṣamṣām-al-Salṭana (the “sword of the sultanate”) and was given the governorate of the Čahār Maḥāl of the Baḵtīārī region.

After the bombardment of the Majles building, Mīrzā Moḥammad Khan Kāšī was appointed governor of Isfahan by Moḥammad-ʿAlī Shah; the new governor ended Ṣamṣām-al-Salṭana’s short tenure as ruler of the Čahār Maḥāl region. It was not long, however, before the people of Isfahan, who had had their fill of the shah’s tyranny, were emboldened by news of the successful resistance against royal forces in Tabrīz. In Jomādā I, 1327/May-June, 1909, acting on the instructions of his younger brother, ʿAlīqolī Khan, who was in Europe at the time and in contact with expatriate liberationist circles, and after obtaining the agreement of Ḥājī Āqā Nūr-Allāh, an influential Isfahani mojtahed (spiritual leader) and supporter of constitutional liberty, and assurance of support from his paternal cousin Ḥājī Ebrāhīm Khan Żarḡām-al-Salṭana, Ṣamṣām-al-Salṭana attacked and took Isfahan with a force of Baḵtīārī cavalry. The Qajar governor having fled without resisting, Ṣamṣām-al-Salṭana became the governor of the province. After learning of the fall of Isfahan, Moḥammad-ʿAlī Shah first delegated Farmānfarmā to confront Ṣamṣām-al-Salṭana; however, when Farmānfarmā declined, the shah turned to several loyal Baḵtīārī khans residing in the capital, among them Amīr Mofaḵḵam Sardār Ẓafar, and ultimately appointed Sardār Ašjaʿ to go to Isfahan. The loyalist khans started out for Isfahan, but, on the pretext of not having the necessary supplies, stopped near Kāšān. In the meantime, Sardār Asʿad ʿAlīqolī Khan, who had returned from Europe via Moḥammara, was sending messages to the Baḵtīārī khans asking them to refrain from familial warfare. He went to Baḵtīārī territory to gather forces and entered Isfahan. Around the time the army of the north was making for Tehran, Sardār Asʿad left Isfahan, also headed for the capital, and accompanied by Ṣamṣām-al-Salṭana’s cavalry. The two armies finally took Tehran and forced the shah’s resignation.

Sometime later, with rumors rife in Tehran that Moḥammad-ʿAlī Shah was preparing to attack Iran, the cabinet of Sepahdār fell and Constitutionalist leaders, who needed Baḵtīārī cavalry to repel the shah’s impending invasion and put down other rebellions, chose Ṣamṣām-al-Salṭana as prime minister with the portfolio of minister of war. With the help of the Majles, Ṣamṣām-al-Salṭana announced a 100,000-toman reward for the capture of Moḥammad-ʿAlī Shah. The American financial agent W. Morgan Shuster (q.v.) also greatly aided the effort to finance the war and military preparations. Finally, with the killing of Aršad-al-Dawla and with Moḥammad-ʿAlī Shah’s attack neutralized, the Russians, using the pretext that Shuster’s efforts ran counter to the financial and nonmaterial interests of the Czarist state, sent a note of protest to Iran and moved their troops from Rašt to Qazvīn. Foreign Minister Woṯūq-al-Dawla visited the Russian embassy to apologize; however, the Russians told him that another ultimatum was in the offing. They demanded that Shuster and his colleagues leave Iran within forty-eight hours, stating that Iran had no right to hire foreign agents without the approval of the Russian and British governments. The British government sided with the Russians; however, the nation of Iran to a person stood up against this presumption, and the Majles rejected the ultimatum. The terrified Regent (nāyeb-al-salṭana) Nāṣer-al-Molk and Prime Minister Ṣamṣām-al-Salṭana, however, accepted it and dissolved the second Majles (2 Moḥarram 1330/23 December 1911); as a result, Ṣamṣām-al-Salṭana gained absolute control of the government and Baḵtīārī influence spread on all levels. During this period, the Russians bombarded the cupola of the Emām Reżā shrine and massacred people in Rašt, Tabrīz, and Urmia. In the south, the British, for their part, were eroding the rights of the people and the interests of the Iranian state. A year and a half later in Ṣafar, 1331/January, 1913, the government of Ṣamṣām-al-Salṭana fell; he retired to his home until Jomādā II, 1337/March, 1918, when he again became prime minister. Four months later, however, because he was unable to cope with a severe famine and restore order in the country, Aḥmad Shah asked him to resign. When he declined, the shah removed him from office and asked Woṯūq-al-Dawla to form a new cabinet; Ṣamṣām-al-Salṭana, though confined to his home, continued to assert that he was prime minister.

Two years later he was appointed governor of Khorasan in the government of Qawām-al-Salṭana; however, because of the revolt of Colonel Moḥammad-Taqī Khan Pesyān in Mašhad against Qawām-al-Salṭana and Ṣamṣām-al-Salṭana’s devotion to Moḥammad-Taqī Khan, he refused to go to Khorasan (Ḵordād, 1300 Š./May-June, 1921). Ṣamṣām-al-Salṭana spent the last years of his life in Čahār Maḥāl of the Baḵtīārī region and died there in 1309 Š./1930 at the age of 82. He was buried with military honors in the Taḵt-e Pūlād cemetery in Isfahan.

Ṣamṣām-al-Salṭana was a sincere man, passionately devoted to the cause of constitutional government. However, true to his tribal background, he ruled the government as a chief; he was also a generous and forgiving man. During his prime-ministership, a commercial council composed of six merchants and six representatives of the state was formed and the gendarmerie of Iran was created by Swedish officers.
