Mirza (ˈmɜːrzə or mɪərˈzɑː; میرزا) is a name of Persian origin. It is used as a surname or prefix to identify patriarchal lineage.
It is a historical royal and noble title, denoting the rank of a royal prince, high nobleman, distinguished military commander, or a scholar. Specifically, it was used as a title by (and today signifies patriarchal lineage to) the various Persian Empires, the Nogai Horde, Shirvanshahs and Circassians of the European Caucasus, as well as the Muslim Rajputs and mainly the Mughals / Moguls, both of the Indian Subcontinent. It was also a title bestowed upon members of the highest aristocracies in Tatar states, such as the Khanates of Kazan and Astrakhan.
The original title Mīrzā or Merzāh is derived from the Persian term Amīrzādeh which literally means child of the Amīr or child of the ruler. Amīrzādeh in turn consists of the Arabic title Amīr (English: Emir), meaning "commander" and the Persian suffix zādeh, meaning "son of" or "lineage of". Due to vowel harmony in Turkic languages, the alternative pronunciation Morza (plural morzalar; derived from Persian) is also used.
Mirza first emerged during the 15th century as an appellative term for members of the Timurid dynasty, adopted in deference to their progenitor, the Central Asian conqueror Timur, who used Amir as his principal title. During the early Timurid period, Mirza preceded a prince's given name, therefore adhering to the Persian fashion, though subsequently the Turkish style was adopted, with the title instead being placed after. This was continued by later rulers such as the Aq Qoyunlus, Safavids and Mughals.
Originally restricted to only kings and princes, the title eventually spread among other social groups, though only the former could have it placed after their given name. During the 16th century, the Safavids conferred it upon high-ranking viziers such as Mirza Shah Hossein and Mirza Ata-Allah Isfahani. By the Qajar period, the title simply marked a person as a clerk or a literate man of consequence.
