Mongol conquests in the context of "Alania"

Gunpowder is the first explosive to have been created in the world. Popularly listed as one of the "Four Great Inventions" of China, it was invented during the late Tang dynasty (9th century) while the earliest recorded chemical formula for gunpowder dates to the Song dynasty (11th century). Knowledge of gunpowder spread rapidly throughout Eurasia, possibly as a result of the Mongol conquests during the 13th century, with written formulas for it appearing in the Middle East between 1240 and 1280 in a treatise by Hasan al-Rammah, and in Europe by 1267 in the Opus Majus by Roger Bacon. It was employed in warfare to some effect from at least the 10th century in weapons such as fire arrows, bombs, and the fire lance before the appearance of the gun in the 13th century. While the fire lance was eventually supplanted by the gun, other gunpowder weapons such as rockets and fire arrows continued to see use in China, Korea, India, and this eventually led to its use in the Middle East, Europe, and Africa. Bombs too never ceased to develop and continued to progress into the modern day as grenades, mines, and other explosive implements. Gunpowder has also been used for non-military purposes such as fireworks for entertainment, or in explosives for mining and tunneling.

The evolution of guns led to the development of large artillery pieces, popularly known as bombards, during the 15th century, pioneered by states such as the Duchy of Burgundy. Firearms came to dominate early modern warfare in Europe by the 17th century. The gradual improvement of cannons firing heavier rounds for a greater impact against fortifications led to the invention of the star fort and the bastion in the Western world, where traditional city walls and castles were no longer suitable for defense. The use of gunpowder technology also spread throughout the Islamic world and to India, Korea, and Japan. The so-called Gunpowder Empires of the early modern period consisted of the Mughal Empire, Safavid Empire, and Ottoman Empire.

A Persian miniature (Persian: نگارگری ایرانی, romanized: negârgari-ye Irâni) is a small Persian painting on paper, whether a book illustration or a separate work of art intended to be kept in an album of such works called a muraqqa. The techniques are broadly comparable to the Western Medieval and Byzantine traditions of miniatures in illuminated manuscripts.

Although there is an equally well-established Persian tradition of wall-painting, the survival rate and state of preservation of miniatures is better, and miniatures are much the best-known form of Persian painting in the West, and many of the most important examples are in Western, or Turkish, museums. Miniature painting became a significant genre in Persian art in the 13th century, receiving Chinese influence after the Mongol conquests, and the highest point in the tradition was reached in the 15th and 16th centuries. The tradition continued, under some Western influence, after this, and has many modern exponents. The Persian miniature was the dominant influence on other Islamic miniature traditions, principally the Ottoman miniature in Turkey, and the Mughal miniature in the Indian subcontinent.

Spāhbad (also spelled spahbod) is a Middle Persian title meaning "army chief" or commander used chiefly in the Sasanian Empire. Originally there was a single spāhbad, called the Ērān-spāhbed, who functioned as the generalissimo of the Sasanian army. From the time of Khosrow I (r. 531–579) on, the office was split in four, with a spāhbad for each of the cardinal directions. After the Muslim conquest of Persia, the spāhbed of the East managed to retain his authority over the inaccessible mountainous region of Tabaristan on the southern shore of the Caspian Sea, where the title, often in its Islamic form ispahbedh (Persian: اسپهبذ; in Arabic: اصبهبذ ʾiṣbahbaḏ), survived as a regnal title until the Mongol conquests of the 13th century. An equivalent title of Persian origin, ispahsālār or sipahsālār, gained great currency across the Muslim world in the 10th–15th centuries.

The title was also adopted by the Armenians (Armenian: սպարապետ, [a]sparapet) and the Georgians (Georgian: სპასპეტი, spaspeti), as well as Khotan (spāta) and the Sogdians (spʾdpt) in Central Asia. It is also attested in Greek sources as aspabedēs (ἀσπαβέδης). The title was revived in the 20th century by the Pahlavi dynasty, in the Modern Persian form sepahbod (سپهبد), equivalent to a three-star Lieutenant General, ranking below arteshbod (full General).

ʿAlāʾ al-Dīn Muḥammad III (Persian: علاءالدین محمد; 1211–1255), more commonly known as ʿAlāʾ al-Dīn (Persian: علاءالدین), son of Jalāl al-Dīn Ḥasan III, was the 26th Nizāri Isma'ilism Imām. He ruled the Nizari Ismaili state from 1221 to 1255. By some accounts, he was considered a respected scholar and the spiritual and worldly leader of the Nisari Ismailis. The intellectual life of Persia has been described as having flourished during his 34-year reign. Allegedly, he was known for his tolerance and pluralism. His reign witnessed the beginnings of the Mongol conquests of Persia and the eastern Muslim world. He was assassinated by an unknown perpetrator on 1 December 1255, and was succeeded by his eldest son, Rukn al-Din Khurshah, in 1255.
