Plague Of Sheroe
The Plague of Shiryue (627–628) or Shiruye's Plague takes its name from the Sasanian monarch Kavad II, whose birth name was Shiruye. The plague was an epidemic that devastated the western provinces of the Sasanian Empire, mainly Mesopotamia (''Asorestan''), killing half of its population, including the reigning Sasanian king Kavad II, who died in the fall of 628 CE, only a few months into his reign. It killed more than 100,000 people in Ctesiphon. The Plague of Shiruye was one of several epidemics that occurred in or close to Iran within two centuries after the first plague pandemic was brought by the Sasanian armies from its campaigns in Constantinople, Syria, and Armenia. There was a subsequent plague outbreak from 634 to 642 during the reign of Yazdegerd III. The death of Kavad II destabilized the Sasanian Empire, which was still trying to recover from the losses incurred by the wars of Kavad II's father, Khosrow II, as well as the raging plague. When the Arabs invaded dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kavad II
Shērōē (also spelled Shīrūya, New Persian: ), better known by his dynastic name of Kavad II ( pal, 𐭪𐭥𐭠𐭲 ''Kawād''; New Persian: قباد ''Qobād'' or ''Qabād''), was king (shah) of the Sasanian Empire briefly in 628. He was the son of Khosrow II (), whom he succeeded after having him overthrown in a coup d'état. Kavad's reign is seen as a turning point in Sasanian history, and has been argued by some scholars as playing a key role in the fall of the Sasanian Empire. Background and rise Sheroe was the son of Khosrow II, the last prominent king (shah) of the Sasanian Empire, and Maria, a Greek woman, who was reportedly a Byzantine princess. Sheroe was later imprisoned by his father, who wanted to ensure the succession of his favorite son Mardanshah, the son of his favorite wife, Shirin. His father's reputation had been ruined during the last phase of the Byzantine–Sasanian War of 602–628. In 627, the Sasanian general Rhahzadh was slain and Dastgerd, the ...

Yazdegerd III
Yazdegerd III (also spelled Yazdgerd III and Yazdgird III; pal, 𐭩𐭦𐭣𐭪𐭥𐭲𐭩) was the last Sasanian King of Kings of Iran from 632 to 651. His father was Shahriyar and his grandfather was Khosrow II. Ascending the throne at the age of eight, the young shah lacked authority and reigned as figurehead In politics, a figurehead is a person who ''de jure'' (in name or by law) appears to hold an important and often supremely powerful title or office, yet ''de facto'' (in reality) exercises little to no actual power. This usually means that they ..., whilst real power was in the hands of the army commanders, courtiers, and powerful members of the aristocracy, who engaged in internecine warfare. The Sasanian Empire was weakened severely by these internal conflicts, resulting in invasions by the Göktürks from the east, and Khazars from the west. It was, however, the Arabs, united under the banner of Islam, who dealt the decisive blow. Yazdegerd was unable to cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
620s In The Sasanian Empire
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler".

Health Disasters In Asia
Health, according to the World Health Organization, is "a state of complete physical, mental and social well-being and not merely the absence of disease and infirmity".World Health Organization. (2006)''Constitution of the World Health Organization''– ''Basic Documents'', Forty-fifth edition, Supplement, October 2006. A variety of definitions have been used for different purposes over time. Health can be promoted by encouraging healthful activities, such as regular physical exercise and adequate sleep, and by reducing or avoiding unhealthful activities or situations, such as smoking or excessive stress. Some factors affecting health are due to individual choices, such as whether to engage in a high-risk behavior, while others are due to structural causes, such as whether the society is arranged in a way that makes it easier or harder for people to get necessary healthcare services. Still, other factors are beyond both individual and group choices, such as genetic disorders. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
7th-century Disasters
The 7th century is the period from 601 ( DCI) through 700 ( DCC) in accordance with the Julian calendar in the Common Era. The spread of Islam and the Muslim conquests began with the unification of Arabia by Muhammad starting in 622. After Muhammad's death in 632, Islam expanded beyond the Arabian Peninsula under the Rashidun Caliphate (632–661) and the Umayyad Caliphate (661–750). The Muslim conquest of Persia in the 7th century led to the downfall of the Sasanian Empire. Also conquered during the 7th century were Syria, Palestine, Armenia, Egypt, and North Africa. The Byzantine Empire suffered setbacks during the rapid expansion of the Caliphate, a mass incursion of Slavs in the Balkans which reduced its territorial limits. The decisive victory at the Siege of Constantinople in the 670s led the empire to retain Asia Minor which assured the existence of the empire. In the Iberian Peninsula, the 7th century was known as the ''Siglo de Concilios'' (century of councils) refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Plague Pandemic
The first plague pandemic was the first historically recorded Old World pandemic of plague, the contagious disease caused by the bacterium ''Yersinia pestis''. Also called the early medieval pandemic, it began with the Plague of Justinian in 541 and continued until 750 or 767; at least fifteen or eighteen major waves of plague following the Justinianic plague have been identified from historical records. The pandemic affected the Mediterranean Basin most severely and most frequently, but also infected the Near East and Northern Europe, and potentially East Asia as well. The Roman emperor Justinian I's name is sometimes applied to the whole series of plague epidemics in late Antiquity, as well as to the Plague of Justinian which struck the Eastern Roman Empire in the early 540s. The pandemic is best known from its first and last outbreaks: the Justinianic Plague of 541549, described by the contemporary Roman historian Procopius, and the late 8th century plague of Naples described b ...

Epidemics
An epidemic (from Greek ἐπί ''epi'' "upon or above" and δῆμος ''demos'' "people") is the rapid spread of disease to a large number of patients among a given population within an area in a short period of time. Epidemics of infectious diseases are generally caused by several factors including a significant change in the ecology of the areal population (e.g., increased stress maybe additional reason or increase in the density of a vector species), the introduction of an emerging pathogen to an areal population (by movement of pathogen or host) or an unexpected genetic change that is in the pathogen reservoir. Generally, epidemics concerns with the patterns of infectious disease spread. An epidemic may occur when host immunity to either an established pathogen or newly emerging novel pathogen is suddenly reduced below that found in the endemic equilibrium and the transmission threshold is exceeded. For example, in meningococcal infections, an attack rate in excess of 15 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plague Of Justinian
The plague of Justinian or Justinianic plague (541–549 AD) was the first recorded major outbreak of the first plague pandemic, the first Old World pandemic of plague, the contagious disease caused by the bacterium ''Yersinia pestis''. The disease afflicted the entire Mediterranean Basin, Europe, and the Near East, severely affecting the Sasanian Empire and the Byzantine Empire and especially Constantinople. The plague is named for the Byzantine Emperor Justinian I (r. 527–565) who according to his court historian Procopius contracted the disease and recovered in 542, at the height of the epidemic which killed about a fifth of the population in the imperial capital. The contagion arrived in Roman Egypt in 541, spread around the Mediterranean Sea until 544, and persisted in Northern Europe and the Arabian Peninsula, until 549. In 2013, researchers confirmed earlier speculation that the cause of the plague of Justinian was ''Yersinia pestis'', the same bacterium responsible f ...

Fall Of The Sasanian Empire
The Muslim conquest of Persia, also known as the Arab conquest of Iran, was carried out by the Rashidun Caliphate from 633 to 654 AD and led to the fall of the Sasanian Empire as well as the eventual decline of the Zoroastrian religion. The rise of the Muslims in Arabia coincided with an unprecedented political, social, economic, and military weakness in Persia. Once a major world power, the Sasanian Empire had exhausted its human and material resources after decades of warfare against the Byzantine Empire. The Sasanian state's internal political situation quickly deteriorated after the execution of King Khosrow II in 628. Subsequently, ten new claimants were enthroned within the next four years.The Muslim Conquest of Persia By A.I. Akram. Ch: 1 Following the Sasanian civil war of 628–632, the empire was no longer centralized.

Khosrow II
Khosrow II (spelled Chosroes II in classical sources; pal, 𐭧𐭥𐭮𐭫𐭥𐭣𐭩, Husrō), also known as Khosrow Parviz (New Persian: , "Khosrow the Victorious"), is considered to be the last great Sasanian king (shah) of Iran, ruling from 590 to 628, with an interruption of one year. Khosrow II was the son of Hormizd IV (reigned 579–590), and the grandson of Khosrow I (reigned 531–579). He was the last king of Iran to have a lengthy reign before the Muslim conquest of Iran, which began five years after his execution. He lost his throne, then recovered it with the help of the Byzantine emperor Maurice, and, a decade later, went on to emulate the feats of the Achaemenids, conquering the rich Roman provinces of the Middle East; much of his reign was spent in wars with the Byzantine Empire and struggling against usurpers such as Bahram Chobin and Vistahm. After the Byzantines killed Maurice, Khosrow II began a war in 602 against the Byzantines. Khosrow II's forces cap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plague (disease)
Plague is an infectious disease caused by the bacterium ''Yersinia pestis''. Symptoms include fever, weakness and headache. Usually this begins one to seven days after exposure. There are three forms of plague, each affecting a different part of the body and causing associated symptoms. Pneumonic plague infects the lungs, causing shortness of breath, coughing and chest pain; bubonic plague affects the lymph nodes, making them swell; and septicemic plague infects the blood and can cause tissues to turn black and die. The bubonic and septicemic forms are generally spread by flea bites or handling an infected animal, whereas pneumonic plague is generally spread between people through the air via infectious droplets. Diagnosis is typically by finding the bacterium in fluid from a lymph node, blood or sputum. Those at high risk may be vaccinated. Those exposed to a case of pneumonic plague may be treated with preventive medication. If infected, treatment is with antibiotic ...
