Khosrow I sent a fleet and a small army under a commander called Vahriz to the area near present Aden , and they marched against the capital San'a'l, which was occupied. Saif, son of Mard-Karib, who had accompanied the expedition, became King sometime between 575 and 577. Thus,

Following Hormizd II's death, northern Arabs started to ravage and plunder the western cities of the empire, even attacking the province of Fars, the birthplace of the Sassanid kings. Meanwhile, Persian nobles killed Hormizd II's eldest son, blinded the second, and imprisoned the third (who later escaped into Roman territory). The throne was reserved for Shapur II , the unborn child of one of Hormizd II's wives who

This foundation isolated the building from vibrations coming from the stones and main gearing and also allowed for the easy re-leveling of the foundation to keep the millstones perfectly horizontal. The lower bedstone was placed in an inset in the husk with the upper runner stone above the level of the husk. American inventor Oliver Evans revolutionized the labor-intensive process of early mills at

Also in 541, Khosrow I entered Lazica at the invitation of its king, captured the main Byzantine stronghold at Petra , and established another protectorate over the country, commencing the Lazic War . A five-year truce agreed to in 545 was interrupted in 547 when Lazica again switched sides and eventually expelled its Persian garrison with Byzantine help;

During his eastern campaign, Yazdegerd II grew suspicious of the Christians in the army and expelled them all from the governing body and army. He then persecuted the Christians in his land, and, to a much lesser extent, the Jews . In order to reestablish Zoroastrianism in Armenia, he crushed an uprising of Armenian Christians at
1100-581: A percentage called the "miller's toll". Early mills in England were almost always built by the local lord of the manor and had the exclusive right (the right of mulcture ) to a proportion on all grain processed in the community. Later, mills were supported by farming communities and the miller received the "miller's toll" in lieu of wages. Most towns and villages had their own mill so that local farmers could easily transport their grain there to be milled. These communities were dependent on their local mill as bread

Yazdegerd also married a Jewish princess, who bore him a son called Narsi. Yazdegerd I's successor was his son Bahram V (421–438), one of the most well-known Sasanian kings and the hero of many myths. These myths persisted even after the destruction of the Sasanian Empire by

Shapur therefore marched east toward Transoxiana to meet the eastern nomads, leaving his local commanders to mount nuisance raids on the Romans. He crushed the Central Asian tribes, and annexed the area as a new province. In the east around 325, Shapur II regained the upper hand against the Kushano-Sasanian Kingdom and took control of large territories in areas now known as Afghanistan and Pakistan . Cultural expansion followed this victory, and Sasanian art penetrated Transoxiana , reaching as far as China. Shapur, along with

The Sassanid dream of restoring the Achaemenid boundaries was almost complete, while the Byzantine Empire was on the verge of collapse. This remarkable peak of expansion was paralleled by a blossoming of Persian art , music , and architecture . While successful at its first stage (from 602 to 622),

However, by 200, Papak had managed to overthrow Gochihr and appoint himself the new ruler of the Bazrangids . Papak's mother, Rodhagh, was the daughter of the provincial governor of Pars . Papak and his eldest son Shapur managed to expand their power over all of Pars. Subsequent events are unclear due to

Later Sassanid inscriptions also claim the submission of the kings of Kushan , Turan and Makuran to Ardashir, although based on numismatic evidence it is more likely that these actually submitted to Ardashir's son, the future Shapur I . In the west, assaults against Hatra , Armenia and Adiabene met with less success. In 230, Ardashir raided deep into Roman territory, and
5300-421: The Sassanids were able to establish a base in South Arabia to control the sea trade with the east. Later, the south Arabian kingdom renounced Sassanid overlordship, and another Persian expedition was sent in 598 that successfully annexed southern Arabia as a Sassanid province, which lasted until the time of troubles after Khosrow II. Khosrow I's reign witnessed the rise of the dihqans (literally, village lords),

In the aftermath of this defeat, Narseh gave up the throne and died a year later, leaving the Sassanid throne to his son, Hormizd II . Unrest spread throughout the land, and while the new king suppressed revolts in Sakastan and Kushan, he was unable to control the nobles and was subsequently killed by Bedouins on

From around 370, however, towards the end of the reign of Shapur II , the Sasanians lost the control of Bactria to invaders from the north: first the Kidarites , then the Hephthalites and finally the Alchon Huns , who would follow up with an invasion of India . These invaders initially issued coins based on Sasanian designs. Various coins minted in Bactria and based on Sasanian designs are extant, often with busts imitating Sassanian kings Shapur II (r. 309 to 379) and Shapur III (r. 383 to 388), adding

Under the command of Khosrow and the Byzantine generals Narses and John Mystacon , the new combined Byzantine-Persian army raised a rebellion against Bahram, defeating him at the Battle of Blarathon in 591. When Khosrow was subsequently restored to power he kept his promise, handing over control of western Armenia and Caucasian Iberia . The new peace arrangement allowed

Emperor Justinian I (527–565) paid Khosrow I 440,000 pieces of gold as a part of the "eternal peace" treaty of 532. In 540, Khosrow broke the treaty and invaded Syria, sacking Antioch and extorting large sums of money from a number of other cities. Further successes followed: in 541 Lazica defected to the Persian side, and in 542

It is claimed that, as the stones grind relatively slowly, the wheat germ is not exposed to the sort of excessive temperatures that could cause the fat from the germ portion to oxidize and become rancid, which would destroy some of the vitamin content. Stone-milled flour has been found to be relatively high in thiamin, compared to roller-milled flour, especially when milled from hard wheat. Gristmills only grind "clean" grains from which stalks and chaff have previously been removed, but historically some mills also housed equipment for threshing , sorting, and cleaning prior to grinding. Modern mills are usually "merchant mills" that are either privately owned and accept money or trade for milling grains or are owned by corporations that buy unmilled grain and then own

The early mills had horizontal paddle wheels, an arrangement which later became known as
7000-405: The head of a large army granted to him by the Hephthalite king, returned to the empire's capital. Jamasp stepped down from his position and returned the throne to his brother. No further mention of Jamasp is made after the restoration of Kavad I, but it is widely believed that he was treated favourably at the court of his brother. The second golden era began after the second reign of Kavad I. With
7100-451: The kingdom. Peroz tried again to drive out the Hephthalites, but on the way to Balkh his army was trapped by the Huns in the desert. Peroz was defeated and killed by a Hephthalite army near Balkh. His army was completely destroyed, and his body was never found. Four of his sons and brothers had also died. The main Sasanian cities of the eastern region of Khorasan − Nishapur , Herat and Marw were now under Hephthalite rule. Sukhra ,
7200-402: The nomad King Grumbates , started his second campaign against the Romans in 359 and soon succeeded in retaking Singara and Amida. In response the Roman emperor Julian struck deep into Persian territory and defeated Shapur's forces at Ctesiphon . He failed to take the capital, however, and was killed while trying to retreat to Roman territory. His successor Jovian , trapped on the east bank of
7300-496: The old wheel mills. In most wheel-driven mills, a large gear-wheel called the pit wheel is mounted on the same axle as the water wheel and this drives a smaller gear-wheel, the wallower , on a main driveshaft running vertically from the bottom to the top of the building. This system of gearing ensures that the main shaft turns faster than the water wheel, which typically rotates at around 10 rpm . The millstones themselves turn at around 120 rpm . They are laid one on top of
7400-414: The other. The bottom stone, called the bed , is fixed to the floor, while the top stone, the runner , is mounted on a separate spindle, driven by the main shaft. A wheel called the stone nut connects the runner's spindle to the main shaft, and this can be moved out of the way to disconnect the stone and stop it turning, leaving the main shaft turning to drive other machinery. This might include driving
7500-417: The petty landholding nobility who were the backbone of later Sassanid provincial administration and the tax collection system. Khosrow I built infrastructure, embellishing his capital and founding new towns with the construction of new buildings. He rebuilt the canals and restocked the farms destroyed in the wars. He built strong fortifications at the passes and placed subject tribes in carefully chosen towns on
7600-449: The physical territory that it controlled, impacting regions as distant as Western Europe , Eastern Africa , and China and India . It also helped shape European and Asian medieval art. With the Muslim conquest of Persia , the influence of Sasanian art , architecture , music , literature , and philosophy was gradually absorbed into nascent Islamic culture , which, in turn, ensured
7700-418: The process. Evans himself did not use the term gristmill to describe his automatic flour mill, which was purpose designed as a merchant mill (he used the more general term "water-mill"). In his book his only reference to "grist" (or "grists") is to the small batches of grain a farmer would bring in to have ground for himself (what would be generally called barter or custom milling). In his book, Evans describes
7800-556: The rich should divide their wives and their wealth with the poor. By adopting the doctrine of the Mazdakites, his intention evidently was to break the influence of the magnates and the growing aristocracy. These reforms led to his being deposed and imprisoned in the Castle of Oblivion in Khuzestan , and his younger brother Jamasp (Zamaspes) became king in 496. Kavad, however, quickly escaped and
7900-416: The runner stone from the outer rim of the stones and is fed down a chute to be collected in sacks on the ground or meal floor. A similar process is used for grains such as wheat to make flour, and for maize to make corn meal . In order to prevent vibrations from the millstones shaking the building apart, they were usually placed on a separate timber foundation, not attached to the mill walls, known as
8000-448: The south with little or no interference from the Parthians. Ardashir was aided by the geography of the province of Fars, which was separated from the rest of Iran. Crowned in 224 at Ctesiphon as the sole ruler of Persia, Ardashir took the title shahanshah , or "King of Kings" (the inscriptions mention Adhur-Anahid as his Banbishnan banbishn , "Queen of Queens", but her relationship with Ardashir has not been fully established), bringing
8100-401: The spread of Iranian culture, knowledge, and ideas throughout the expanding Muslim world . Officially, the empire was known as the Empire of the Iranians ( Middle Persian : 𐭠𐭩𐭥𐭠𐭭𐭱𐭲𐭥𐭩 , ērānšahr , Parthian : 𐭀𐭓𐭉𐭀𐭍𐭇𐭔𐭕𐭓 , aryānšahr , Greek : Ἀριανῶν ἔθνος , Arianōn ethnos ), the term is first attested in the trilingual Great Inscription of Shapur I , where
8200-485: The support of the Hephthalites , Kavad launched a campaign against the Romans. In 502, he took Theodosiopolis in Armenia, but lost it soon afterwards. In 503 he took Amida on the Tigris. In 504, an invasion of Armenia by the western Huns from the Caucasus led to an armistice, the return of Amida to Roman control and a peace treaty in 506. In 521/522 Kavad lost control of Lazica , whose rulers switched their allegiance to
8300-518: The two empires to focus on military matters elsewhere: Khosrow focused on the Sassanid Empire's eastern frontier while Maurice restored Byzantine control of the Balkans . Circa 600, the Hephthalites had been raiding the Sassanid Empire as far as Spahan in central Iran. The Hephthalites issued numerous coins imitating the coinage of Khosrow II. In c. 606/607 , Khosrow recalled Smbat IV Bagratuni from Persian Armenia and sent him to Iran to repel
8400-595: The use of a conveyor but easier to build); and the Descender, an endless strap (leather or flannel) in a trough that is angled downward, the strap helps to move the ground flour in the trough. Most importantly, he integrated these into a single continuous process, the overall design later becoming known as the Automatic (or Automated) mill. In 1790 he received the third Federal patent for his process. In 1795 he published "The Young Mill-Wright and Miller’s Guide" which fully described
8500-582: The war resumed but remained confined to Lazica, which was retained by the Byzantines when peace was concluded in 562. In 565, Justinian I died and was succeeded by Justin II (565–578), who resolved to stop subsidies to Arab chieftains to restrain them from raiding Byzantine territory in Syria. A year earlier, the Sassanid governor of Armenia, Chihor-Vishnasp of the Suren family, built a fire temple at Dvin near modern Yerevan , and he put to death an influential member of
8600-476: Was Springtime for Henry featuring Edward Everett Horton . It opened on July 1, 1939. The Bucks County Playhouse became a summer theater . It was the starting point for many actors and became a place where plays slated for Broadway were tried out. Neil Simon 's Barefoot in the Park , starring Robert Redford and Elizabeth Ashley , had its premiere at the theater in 1963. The Bucks County Playhouse Conservancy,
8700-522: Was a staple part of the diet. Classical mill designs are usually water-powered , though some are powered by the wind or by livestock. In a watermill a sluice gate is opened to allow water to flow onto, or under, a water wheel to make it turn. In most watermills the water wheel was mounted vertically, i.e., edge-on, in the water, but in some cases horizontally (the tub wheel and so-called Norse wheel ). Later designs incorporated horizontal steel or cast iron turbines and these were sometimes refitted into
8800-540: Was also amenable to the wishes of the Zoroastrian priesthood. During his reign, the Sassanid capital Ctesiphon was sacked by the Romans under Emperor Carus , and most of Armenia, after half a century of Persian rule, was ceded to Diocletian . Succeeding Bahram III (who ruled briefly in 293), Narseh embarked on another war with the Romans. After an early success against the Emperor Galerius near Callinicum on
8900-426: Was appointed shah (king), he moved his capital further to the south of Pars and founded Ardashir-Khwarrah (formerly Gur , modern day Firuzabad ). The city, well protected by high mountains and easily defensible due to the narrow passes that approached it, became the center of Ardashir's efforts to gain more power. It was surrounded by a high, circular wall, probably copied from that of Darabgerd. Ardashir's palace
9000-503: Was captured by Shapur, remaining his prisoner for the rest of his life. Shapur celebrated his victory by carving the impressive rock reliefs in Naqsh-e Rostam and Bishapur , as well as a monumental inscription in Persian and Greek in the vicinity of Persepolis . He exploited his success by advancing into Anatolia (260), but withdrew in disarray after defeats at the hands of the Romans and their Palmyrene ally Odaenathus , suffering
9100-419: Was crowned in utero : the crown was placed upon his mother's stomach. During his youth the empire was controlled by his mother and the nobles. Upon coming of age, Shapur II assumed power and quickly proved to be an active and effective ruler. He first led his small but disciplined army south against the Arabs, whom he defeated, securing the southern areas of the empire. He then began his first campaign against
9200-443: Was defeated at the Battle of Dara . In the same year, a second Persian army under Mihr-Mihroe was defeated at Satala by Roman forces under Sittas and Dorotheus, but in 531 a Persian army accompanied by a Lakhmid contingent under Al-Mundhir III defeated Belisarius at the Battle of Callinicum , and in 532 an "eternal peace" was concluded. Kavad succeeded in restoring order in the interior and fought with general success against
9300-506: Was given refuge by the Hephthalite king. Jamasp (496–498) was installed on the Sasanian throne upon the deposition of Kavad I by members of the nobility. He was a good and kind king; he reduced taxes in order to improve the condition of the peasants and the poor. He was also an adherent of the mainstream Zoroastrian religion, diversions from which had cost Kavad I his throne and freedom. Jamasp's reign soon ended, however, when Kavad I, at
9400-603: Was killed by his brother Peroz in 459. At the beginning of the 5th century, the Hephthalites (White Huns), along with other nomadic groups, attacked Iran. At first Bahram V and Yazdegerd II inflicted decisive defeats against them and drove them back eastward. The Huns returned at the end of the 5th century and defeated Peroz I (457–484) in 483. Following this victory, the Huns invaded and plundered parts of eastern Iran continually for two years. They exacted heavy tribute for some years thereafter. These attacks brought instability and chaos to
9500-519: Was on the north side of the city; remains of it are extant. After establishing his rule over Pars, Ardashir rapidly extended his territory, demanding fealty from the local princes of Fars, and gaining control over the neighbouring provinces of Kerman , Isfahan , Susiana and Mesene . This expansion quickly came to the attention of Artabanus IV, the Parthian king, who initially ordered the governor of Khuzestan to wage war against Ardashir in 224, but Ardashir
9600-480: Was overthrown by a palace coup and his son Khosrow II (590–628) placed on the throne. However, this change of ruler failed to placate Bahram, who defeated Khosrow, forcing him to flee to Byzantine territory, and seized the throne for himself as Bahram VI. Khosrow asked the Byzantine Emperor Maurice (582–602) for assistance against Bahram, offering to cede the western Caucasus to the Byzantines. To cement
9700-515: Was probably typical throughout western and southern Europe. From this time onward, water wheels began to be used for purposes other than grist milling. In England, the number of mills in operation followed population growth, and peaked at around 17,000 by 1300. Limited extant examples of gristmills can be found in Europe from the High Middle Ages . An extant well-preserved waterwheel and gristmill on
9800-494: Was returned to Roman domination, with the fort of Ziatha as its border; Caucasian Iberia would pay allegiance to Rome under a Roman appointee; Nisibis, now under Roman rule, would become the sole conduit for trade between Persia and Rome; and Rome would exercise control over the five satrapies between the Tigris and Armenia: Ingilene , Sophanene ( Sophene ), Arzanene ( Aghdznik ), Corduene , and Zabdicene (near modern Hakkâri , Turkey). The Sassanids ceded five provinces west of
9900-559: Was to be later confirmed by the Nvarsak Treaty (484). At the beginning of his reign in 441, Yazdegerd II assembled an army of soldiers from various nations, including his Indian allies, and attacked the Byzantine Empire , but peace was soon restored after some small-scale fighting. He then gathered his forces in Nishapur in 443 and launched a prolonged campaign against the Kidarites . After
10000-513: Was victorious in the ensuing battles. In a second attempt to destroy Ardashir, Artabanus himself met Ardashir in battle at Hormozgan, where the former met his death. Following the death of the Parthian ruler, Ardashir went on to invade the western provinces of the now defunct Parthian Empire. At that time the Arsacid dynasty was divided between supporters of Artabanus IV and Vologases VI , which probably allowed Ardashir to consolidate his authority in
