Mirza Mousa Vazir-Lashkar Ashtiani (Persian: میرزا موسی وزیرلشکر آشتیانی; d. April 29, 1881) was a prominent statesman during the reign of Naser al-Din Shah Qajar.^[1]

Mirza Mousa followed the family tradition and entered the Divan-e Estifa' (دیوان استیفا; lit. Ministry of Finance) at a young age. In 1849, he was stationed in Qazvin, where he demonstrated competence in suppressing a local uprising that had led to the closure of the bazaar.^[2] His performance earned him the attention of Amir Kabir, who subsequently appointed him as the financial administrator of Khorasan. At that time, Khorasan was governed by Morad Mirza Hessam al-Saltaneh.^[1]

In 1850, Amir Kabir was dismissed from office, and Mirza Aqa Khan Nuri became Grand Vizier.^[1] During this period, Mirza Mousa was promoted to the position of Minister of Khorasan. However, tensions soon arose between him and Hesam o-Saltaneh over financial matters in the province. While Hesam o-Saltaneh sought his dismissal, Mirza Aqa Khan insisted on retaining him. Although the disputes were eventually resolved, the Grand Vizier ultimately ordered Mirza Mousa's removal from office.^[3]

After a period of political inactivity, Mirza Mousa was appointed Minister of Qazvin. Eventually, he was granted independent governorship of the province.^[1]

In 1871, Naser al-Din Shah entrusted the administration of military affairs to Mirza Hossein Khan Sepahsalar. Given his familiarity with Mirza Mousa, Sepahsalar requested the Shah to appoint him as Vazir-Lashkar (وزیر لشکر; lit. Minister of the Army) and put him in charge of military finances.^[1][2] One of his first initiatives in this role was to conduct an audit of the Qurkhaneh (قورخانه; lit. state arsenal) and compile a comprehensive inventory of military equipment stored in Tehran and other regions. These records had not been updated since the tenure of Amir Kabir.^[1]

Mirza Mousa remained in office until his death in 1881.^[3]

One of Mirza Musa's wives was Amirzadeh Khanom, the daughter of Mahmoud Mirza (the fifteenth son of Fath-Ali Shah Qajar). They had four children:^[4]

1. Mirza Hadi Montaser al-Molk Dadvar
2. Mirza Ali Ghavam al-Saltaneh Dadvar, father of Abdollah Dadvar, a renowned setar player
3. Vosuq al-Saltaneh Dadvar, Minister of War and Member of Parliament
4. Mokarram al-Saltaneh Dadvar

Another wife, Mehrmah Khanum Ismat al-Saltaneh, was the widow of Mirza Mohammad Qavam al-Dawla. From this marriage, they had a son named Mousa Moshir Akram. Mirza Mousa also had a third wife, with whom he had two daughters.^[4]
