Afsharid IranAfsharid Iran (ایران افشاری), also referred as the Afsharid Empire, was an Iranian empire established by the Turkoman Afshar tribe in Iran's north-eastern province of Khorasan, ruling Iran (Persia). The state was ruled by the Afsharid dynasty in the mid-eighteenth century. The dynasty was founded in 1736 by the brilliant military commander Nader Shah, who deposed the last member of the Safavid dynasty and proclaimed himself as the Shah of Iran. During Nader's reign, Iran reached its greatest extent since the Sasanian Empire.
Tahirid dynastyThe Tahirid dynasty (Tâheriyân, t̪hɒːheɾiˈjɒːn) was a culturally Arabized Sunni Muslim dynasty of Persian dehqan origin, that ruled as governors of Khorasan from 821 to 873 as well as serving as military and security commanders in Abbasid Baghdad until 891. The dynasty was founded by Tahir ibn Husayn, a leading general in the service of the Abbasid caliph al-Ma'mun. For his support of al-Ma'mun in the Fourth Fitna, he was granted the governance of Khorasan. The Tahirids initially made their capital in Merv but later moved to Nishapur.
Gunpowder empiresThe gunpowder empires, or Islamic gunpowder empires, is a collective term coined by Marshall G. S. Hodgson and William H. McNeill at the University of Chicago, referring to three early modern Muslim empires: the Ottoman Empire, Safavid Empire and the Mughal Empire, in the period they flourished from mid-16th to the early 18th century. These three empires were among the most stable empires of the early modern period, leading to commercial expansion, and patronage of culture, while their political and legal institutions were consolidated with an increasing degree of centralization.
