65-461: Macriani is the name of three Roman usurpers – a father and two sons – who tried to gain the Roman throne from Emperor Gallienus . All three died in 261 A.D. They were: Macrianus Major , the father Macrianus Minor , first son Quietus , second son [REDACTED] Index of articles associated with the same name This set index article includes

130-469: A plague outbreak in five Indian states caused an estimated 700 infections (including 52 deaths) and triggered a large migration of Indians within India as they tried to avoid the disease. It was during the 1894 Hong Kong plague outbreak that Alexandre Yersin isolated the bacterium responsible ( Yersinia pestis ), a few days after Japanese bacteriologist Kitasato Shibasaburō had isolated it. However,

195-524: A certain number of legions, according to the degree of pacification that they required. Thus, the governors of, for instance, Moesia or Pannonia in the Danubian border had huge military contingents on their hands. The greater the number of legions a provincial governor had, the greater the temptation to make a bid to the throne. And indeed, most usurpation attempts came from the Asian province of Syria, and

260-680: A human case of bubonic plague was reported. Officials responded by activating a city-wide plague-prevention system for the remainder of the year. Also in July 2020, in Mongolia, a teenager died from bubonic plague after consuming infected marmot meat. Yersinia pestis has been discovered in archaeological finds from the Late Bronze Age (~3800 BP ). The bacteria is identified by ancient DNA in human teeth from Asia and Europe dating from 2,800 to 5,000 years ago. Some authors have suggested that

325-470: A large grouping of Roman legions ; or prefects of the Praetorian Guard, which had control of Rome , where the imperial palace still lay. The danger of usurpation was greater after the death of an emperor when his successor was not accepted by all provinces. Usually, the legions acclaimed their own commander as emperor on news of the accession of a less popular man. The acclaimed emperor, usually

455-408: A natural death (from the plague ). However, there were also 38 usurpers who raised revolts across the empire, a clear sign that the security of the frontiers was not the only problem within the Roman world. Usurpation attempts were a constant worry for the emperors in this period since it was a too-common method of acceding the throne. Successful usurpers were usually provincial governors; commanders of

520-421: A provincial governor, would then march to Italy or where the opponent was stationed to contest for the purple. However, since legionaries disliked fighting against their brothers in arms, battles between legions rarely transpired. Two main factors decided the success of a usurpation attempt: the loyalty of the legionaries, which were heavily dependent on the amount of booty or monetary prizes promised on victory, and

585-467: A role in controlling the 2003 Oran outbreak of the bubonic plague. Another means of prevention in large European cities was a city-wide quarantine to not only limit interaction with people who were infected, but also to limit the interaction with the infected rats. Several classes of antibiotic are effective in treating bubonic plague. These include aminoglycosides such as streptomycin and gentamicin , tetracyclines (especially doxycycline ), and

650-516: A role in increasing the transmission effectiveness of the plague. The plague resurfaced for a third time in the mid-19th century; this is also known as "the modern pandemic". Like the two previous outbreaks, this one also originated in Eastern Asia , most likely in Yunnan , a province of China, where there are several natural plague foci . The initial outbreaks occurred in the second half of

715-455: A usurper, is an example of that kind. Other usurpers, like Philip the Arab , became emperor by a planned murder directed at an established sovereign (in that case, Gordian III ). However successful, the usurpation procedure always left the new emperor in a somewhat fragile political position since the throne had been attained by violent means. The danger of another usurper was always present, and

780-478: Is a result of the bacteria infecting organs through the bloodstream. Other forms of the disease include septicemic plague and pneumonic plague , in which the bacterium reproduces in the person's blood and lungs respectively. Laboratory testing is required in order to diagnose and confirm plague. Ideally, confirmation is through the identification of Y. pestis culture from a patient sample. Confirmation of infection can be done by examining serum taken during

845-476: Is also known to spread to the lungs and become the disease known as the pneumonic plague . Symptoms appear two to seven days after getting bitten and they include: The best-known symptom of bubonic plague is one or more infected, enlarged, and painful lymph nodes, known as buboes . Buboes associated with the bubonic plague are commonly found in the armpits, upper femoral area, groin, and neck region. These buboes will grow and become more painful over time, often to

The Flavian dynasty started with Vespasian , only to end with

975-547: Is highest in the summer and early fall. The successful control of rat populations in dense urban areas is essential to outbreak prevention. One example is the use of a machine called the Sulfurozador , used to deliver sulphur dioxide to eradicate the pest that spread the bubonic plague in Buenos Aires, Argentina during the early 18th century. Targeted chemoprophylaxis , sanitation , and vector control also played

1040-538: Is through public health measures such as not handling dead animals in areas where plague is common. While vaccines against the plague have been developed, the World Health Organization recommends that only high-risk groups, such as certain laboratory personnel and health care workers, get inoculated. Several antibiotics are effective for treatment, including streptomycin , gentamicin , and doxycycline . Without treatment, plague results in

1105-598: The Black Death that swept through Asia, Europe, and Africa in the 14th century and killed an estimated 50 million people, including about 25% to 60% of the European population. Because the plague killed so many of the working population, wages rose due to the demand for labor. Some historians see this as a turning point in European economic development . The disease is also considered to have been responsible for

1170-507: The Great Plague of London in 1665–66. Later works, such as Albert Camus 's novel The Plague or Ingmar Bergman 's film The Seventh Seal have used bubonic plague in settings, such as quarantined cities in either medieval or modern times, as a backdrop to explore themes including the breakdown of society, institutions, and individuals during the plague; the cultural and psychological existential confrontation with mortality; and

1235-788: The Plague of Justinian , originating in the Eastern Roman Empire in the 6th century CE, as well as the third epidemic , affecting China , Mongolia , and India , originating in the Yunnan Province in 1855. The term bubonic is derived from the Greek word βουβών , meaning ' groin ' . The bubonic plague is an infection of the lymphatic system , usually resulting from the bite of an infected flea, Xenopsylla cheopis (the Oriental rat flea ). Several flea species carried

1300-548: The Western canon . The Decameron , by Boccaccio, is notable for its use of a frame story involving individuals who have fled Florence for a secluded villa to escape the Black Death. First-person, sometimes sensationalized or fictionalized, accounts of living through plague years have also been popular across centuries and cultures. For example, Samuel Pepys 's diary makes several references to his first-hand experiences of

1365-475: The Y. pestis bacteria become localized in an inflamed lymph node , where they begin to colonize and reproduce. Infected lymph nodes develop hemorrhages, which result in the death of tissue. Y. pestis bacilli can resist phagocytosis and even reproduce inside phagocytes and kill them. As the disease progresses, the lymph nodes can hemorrhage and become swollen and necrotic . Bubonic plague can progress to lethal septicemic plague in some cases. The plague

1430-516: The besiegers and from them penetrated the town. The Mongol forces catapulted plague-infested corpses into Caffa as a form of attack, one of the first known instances of biological warfare . When spring arrived, the Italian merchants fled on their ships, unknowingly carrying the Black Death. Carried by the fleas on rats, the plague initially spread to humans near the Black Sea and then outwards to

1495-516: The fluoroquinolone ciprofloxacin . Mortality associated with treated cases of bubonic plague is about 1–15%, compared to a mortality of 40–60% in untreated cases. People potentially infected with the plague need immediate treatment and should be given antibiotics within 24 hours of the first symptoms to prevent death. Other treatments include oxygen, intravenous fluids, and respiratory support. People who have had contact with anyone infected by pneumonic plague are given prophylactic antibiotics. Using

1560-553: The 18th century. The disease remained localized in Southwest China for several years before spreading. In the city of Canton , beginning in January 1894, the disease had killed 80,000 people by June. Daily water traffic with the nearby city of Hong Kong rapidly spread the plague there, killing over 2,400 within two months during the 1894 Hong Kong plague . The third pandemic spread the disease to port cities throughout

1625-477: The 3rd century had profound effects in the empire's bureaucratic and military organisation. Fear of potential rivals was to be the main driving force for the evolution of the Roman world from the early to the late Empire. One of the most striking changes was the division and multiplication of the Roman provinces . Provinces were ruled by a governor, whether a proconsul , propraetor or procurator , and were ascribed

1690-468: The 8th century. Because the infectious disease spread inland by the transferring of merchandise through Justinian's efforts in acquiring luxurious goods of the time and exporting supplies, his capital became the leading exporter of the bubonic plague. Procopius, in his work Secret History , declared that Justinian was a demon of an emperor who either created the plague himself or was being punished for his sinfulness. Medieval society's increasing population

1755-698: The Democratic Republic of the Congo had the most plague cases, with over 1,100 cases in the Democratic Republic of the Congo alone. From 1,000 to 2,000 cases are conservatively reported per year to the WHO . From 2012 to 2017, reflecting political unrest and poor hygienic conditions, Madagascar began to host regular epidemics. Between 1900 and 2015, the United States had 1,036 human plague cases, with an average of 9 cases per year. In 2015, 16 people in

1820-641: The East, the Persian Empire grew bolder in its attacks on the Roman communities. Moreover, since individual initiative was a common way to assume the imperial purple, the giving of important commands to competent generals was asking for trouble. Jealousy and fear often prevented the presence of the right man to deal with a specific threat, and so marginal provinces were often raided, sacked or conquered. The only usurpers whose early life and specific circumstances of rebellion are known with reasonable certainty are

1885-616: The Rhine and Danube provinces, frontier provinces with large military presence. Thus, provinces were slowly divided into smaller units to avoid concentration of power and military capacity in the hands of one man. Syria is a perfect example: a single province in AD 14, it was in the mid-3rd century divided into four different administrative regions: Tres Daciae, Cappadocia, Syria Coele and Syria Palestina. Similarly, Moesia and Pannonia were divided into Superior and Inferior (Upper and Lower) halves; Dardania

In the spring of 542, the plague arrived in Constantinople, working its way from port city to port city and spreading around the Mediterranean Sea , later migrating inland eastward into Asia Minor and west into Greece and Italy. The Plague of Justinian is said to have been "completed" in the middle of

2015-443: The area closest to where the bacteria entered the skin. Acral necrosis , the dark discoloration of skin, is another symptom. Occasionally, swollen lymph nodes, known as " buboes ", may break open. The three types of plague are the result of the route of infection: bubonic plague, septicemic plague , and pneumonic plague . Bubonic plague is mainly spread by infected fleas from small animals . It may also result from exposure to

2080-540: The assassination of his second son, Domitian . Throughout most of the 2nd century, the empire enjoyed relative stability under the rule of the Nerva–Antonine dynasty , but the next century would be characterised by endemic political instability, one of the factors that eventually contributed to the fall of the Western Roman Empire . Commodus , the last emperor of the Nerva–Antonine dynasty dynasty,

2145-457: The body fluids from a dead plague-infected animal. Mammals such as rabbits , hares , and some cat species are susceptible to bubonic plague, and typically die upon contraction. In the bubonic form of plague, the bacteria enter through the skin through a flea bite and travel via the lymphatic vessels to a lymph node , causing it to swell. Diagnosis is made by finding the bacteria in the blood, sputum , or fluid from lymph nodes. Prevention

2210-508: The broad-based antibiotic streptomycin has proven to be dramatically successful against the bubonic plague within 12 hours of infection. Globally between 2010 and 2015, there were 3,248 documented cases, which resulted in 584 deaths. The countries with the greatest number of cases are the Democratic Republic of the Congo , Madagascar , and Peru . For over a decade since 2001, Zambia, India, Malawi, Algeria, China, Peru, and

2275-449: The bubonic plague, such as Pulex irritans (the human flea ), Xenopsylla cheopis , and Ceratophyllus fasciatus . Xenopsylla cheopis was the most effective flea species for transmission. The flea is parasitic on house and field rats and seeks out other prey when its rodent host dies. Rats were an amplifying factor to bubonic plague due to their common association with humans as well as the nature of their blood. The rat's blood allows

2340-652: The country. Unusually, most of the cases were pneumonic rather than bubonic. In June 2018, a child was confirmed to be the first person in Idaho to be infected by bubonic plague in nearly 30 years. A couple died in May 2019, in Mongolia, while hunting marmots . Another two people in the province of Inner Mongolia, China, were treated in November 2019 for the disease. In July 2020, in Bayannur , Inner Mongolia of China,

2405-408: The death of 30% to 90% of those infected. Death, if it occurs, is typically within 10 days. With treatment, the risk of death is around 10%. Globally between 2010 and 2015 there were 3,248 documented cases, which resulted in 584 deaths. The countries with the greatest number of cases are the Democratic Republic of the Congo , Madagascar , and Peru . The plague is considered the likely cause of

2470-401: The early and late stages of infection . To quickly screen for the Y. pestis antigen in patients, rapid dipstick tests have been developed for field use. Samples taken for testing include: Bubonic plague outbreaks are controlled by pest control and modern sanitation techniques. This disease uses fleas commonly found on rats as a vector to jump from animals to humans. The mortality rate

2535-592: The empire. Legio II Parthica , which was garrisoned in the Alban mountains outside Rome from the time of Septimius Severus, was among the first comitatenses created. Men had to be removed from the frontier garrisons to create the internal legions. A smaller number of border legions meant less-secure borders and eventually, raids from the Germanic and Gothic tribes against the Rhine and the Danube became more frequent. In

2600-475: The first measures taken were inevitably to put trusted men into important commands. Frequently, the emperor embellished his ancestry and early life to enhance his credibility or the right to the throne. Mentions of obscure genealogical relations with previous popular emperors were common and certainly confused historians. However, most of all, the usurper maneuvered to keep his legions happy since he owed his power to their continued loyalty. The usurpation mania of

2665-416: The invincibility of the emperor or added by later writers to embellish their own prose. Bubonic plague Bubonic plague is one of three types of plague caused by the bacterium Yersinia pestis . One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever , headaches , and vomiting , as well as swollen and painful lymph nodes occurring in

2730-533: The latter's description was imprecise and also expressed doubts of its relation to the disease, and thus the bacterium is today only named after Yersin. The scale of death and social upheaval associated with plague outbreaks has made the topic prominent in many historical and fictional accounts since the disease was first recognized. The Black Death in particular is described and referenced in numerous contemporary sources , some of which, including works by Chaucer , Boccaccio , and Petrarch , are considered part of

2795-575: The mass mortality rate cheapened life and thus increased warfare, crime, popular revolt, waves of flagellants , and persecution. The Black Death originated in Central Asia and spread from Italy and then throughout other European countries. Arab historians Ibn Al-Wardni and Almaqrizi believed the Black Death originated in Mongolia. Chinese records also show a huge outbreak in Mongolia in the early 1330s. In 2022, researchers presented evidence that

2860-413: The ones who would become emperors. The unsuccessful usurpation attempts inevitably ended with the rebel's execution, murder or suicide and the subsequent erasure of his life from all records. That often causes confusion in the contemporaneous sources that are contradictory in the details of a certain rebellion. For instance, the usurper Uranius is placed by some in the reign of Elagabalus and by others in

2925-550: The origin of the plague and how it traveled through the continent. Mitochondrial DNA of modern rats in Western Europe indicated that these rats came from two different areas, one being Africa and the other unclear. The research regarding this pandemic has greatly increased with technology. Through archaeo-molecular investigation, researchers have discovered the DNA of plague bacillus in the dental core of those that fell ill to

2990-589: The other hand, a man capable of sustaining a rebellion for a couple of months in a remote area might fail to produce his own coins by lack of access to the instruments of minting technology. Later assessment of usurpations demonstrated that some are questionable or even fictitious. Gallienus was the emperor who suffered greatest number of usurpations, with a record of 14 attempts (excluding the Gallic Empire secession) in 15 years of rule. However, three of these are clear fabrications, either contemporaneous to show

3055-406: The plague as an allegory raising contemporary moral or spiritual questions. Some of the earliest instances of biological warfare were said to have been products of the plague, as armies of the 14th century were recorded catapulting diseased corpses over the walls of towns and villages to spread the pestilence. This was done by Jani Beg when he attacked the city of Kaffa in 1343. Later, plague

3120-615: The plague originated near Lake Issyk-Kul in Kyrgyzstan . The Mongols had cut the trade route (the Silk Road ) between China and Europe, which halted the spread of the Black Death from eastern Russia to Western Europe. The European epidemic may have begun with the siege of Caffa , an attack that Mongols launched on the Italian merchants' last trading station in the region, Caffa , in the Crimea . In late 1346, plague broke out among

3185-712: The plague was responsible for the Neolithic decline . The first recorded epidemic affected the Sasanian Empire and their arch-rivals, the Eastern Roman Empire (Byzantine Empire) and was named the Plague of Justinian (541–549 AD) after emperor Justinian I , who was infected but survived through extensive treatment. The pandemic resulted in the deaths of an estimated 25 million (6th century outbreak) to 50 million people (two centuries of recurrence). The historian Procopius wrote, in Volume II of History of

3250-538: The plague. Analysis of teeth of the deceased allows researchers to further understand both the demographics and mortuary patterns of the disease. For example, in 2013 in England, archeologists uncovered a burial mound to reveal 17 bodies, mainly children, who had died of the Bubonic plague. They analyzed these burial remains using radiocarbon dating to determine they were from the 1530s, and dental core analysis revealed

3315-433: The point of bursting. Symptoms include heavy breathing, continuous vomiting of blood ( hematemesis ), aching limbs, coughing, and extreme pain caused by the decay or decomposition of the skin while the person is still alive. Additional symptoms include extreme fatigue, gastrointestinal problems, spleen inflammation, lenticulae (black dots scattered throughout the body), delirium, coma , organ failure, and death. Organ failure

3380-515: The presence of Yersinia pestis. Other evidence for rats that are currently still being researched consists of gnaw marks on bones, predator pellets and rat remains that were preserved in situ . This research allows individuals to trace early rat remains to track the path traveled and in turn connect the impact of the Bubonic Plague to specific breeds of rats. Burial sites, known as plague pits, offer archaeologists an opportunity to study

3445-418: The rat population in the area is wiped out from a mass infection. Furthermore, in areas with a large population of rats, the animals can harbor low levels of the plague infection without causing human outbreaks. With no new rat inputs being added to the population from other areas, the infection only spread to humans in very rare cases of overcrowding. After being transmitted via the bite of an infected flea,

3510-409: The rat to withstand a major concentration of the plague. The bacteria form aggregates in the gut of infected fleas, and this results in the flea regurgitating ingested blood, which is now infected, into the bite site of a rodent or human host. Once established, the bacteria rapidly spread to the lymph nodes of the host and multiply. The fleas that transmit the disease only directly infect humans when

3575-481: The rest of Europe as a result of people fleeing from one area to another. Rats migrated with humans, traveling among grain bags, clothing, ships, wagons, and grain husks. Continued research indicates that black rats , those that primarily transmitted the disease, prefer grain as a primary meal. Due to this, the major bulk grain fleets that transported major city's food shipments from Africa and Alexandria to heavily populated areas, and were then unloaded by hand, played

3640-677: The throne. Although initially a usurper, Severus managed to remain in power for the next 18 years and died a natural death while he was campaigning in northern Britain . The 235 death of Severus Alexander , the last emperor of the Severan dynasty , triggered what historians call the Crisis of the Third Century . From 235 to the accession of Diocletian and the establishment of the Tetrarchy in 286, Rome saw 28 emperors, only two of whom had

3705-517: The time of Gallienus . Every new emperor, either legal or illegal, marked the beginning of his rule by minting new coins, both to have the prestige of declaring oneself as Augustus and to pay the loyal soldiers their share. Thus, coinage is often the only evidence of a determined usurpation, but the number of coin types with the effigy of a usurper might not be equal to the total number of usurpations. The presence of minting facilities certainly allowed short-term usurpers to release their coinage, but on

3770-441: The trust of the military abilities of the commander upon which depended morale. Failure of either part to fulfill one or two of the criteria normally resulted in a mutiny and the death at the hands of their own soldiers. Since the emperors had the status quo and political credibility behind them, the usurper had to be a charismatic man to avoid doubts in his ranks and an untimely death. Valerian I , who defeated Aemilianus , himself

3835-606: The western United States developed plague, including 2 cases in Yosemite National Park . These US cases usually occur in rural northern New Mexico, northern Arizona, southern Colorado, California, southern Oregon, and far western Nevada. In November 2017, the Madagascar Ministry of Health reported an outbreak to the WHO (World Health Organization) with more cases and deaths than any recent outbreak in

3900-688: The world in the second half of the 19th century and the early 20th century via shipping routes. The plague infected people in Chinatown in San Francisco from 1900 to 1904, and in the nearby locales of Oakland and the East Bay again from 1907 to 1909. During the former outbreak, in 1902, authorities made permanent the Chinese Exclusion Act , a law originally signed into existence by President Chester A. Arthur in 1882. The Act

3965-427: Was later separated from Moesia and Pannonia was further divided into Prima, Valeria, Savia and Secunda. As the fear of civil war increased, the emperor felt the need of legions permanently in his reach to be deployed against possible internal threats. That caused the geographic division of the army into limitanei legions, which remained in the borders, and comitatenses , which were stationed in strategic points within

4030-571: Was put to deadly halt when, in the Late Middle Ages , Europe experienced the deadliest disease outbreak in history. They called it the Great Dying or The Great Pestilence, later coined The Black Death. Lasting in potency for roughly six years, 1346–1352, the Black Death claimed one-third of the European human population, with mortality rates as high as 70%–80%. Some historians believe that society subsequently became more violent as

4095-454: Was remembered by contemporaneous chronicles as an unpopular ruler notorious for his extravagance and cruelty, and he was assassinated in 192. Without sons to be his heir, a struggle for power immediately broke out among the governors of the most important provinces. Pertinax was elevated to the purple and recognized by his peers, but after his murder by a restive Praetorian Guard , Septimius Severus decided to make his bid for power and usurped

4160-576: Was supposed to last for 10 years, but was renewed in 1892 with the Geary Act , then followed by the 1902 decision. The last major outbreak in the United States occurred in Los Angeles in 1924, though the disease is still present in wild rodents and can be passed to humans who come in contact with them. According to the World Health Organization , the pandemic was considered active until 1959, when worldwide casualties dropped to 200 per year. In 1994,

4225-969: Was used during the Second Sino-Japanese War as a bacteriological weapon by the Imperial Japanese Army . These weapons were provided by Shirō Ishii 's units and used in experiments on humans before being used in the field. For example, in 1940, the Imperial Japanese Army Air Service bombed Ningbo with fleas carrying the bubonic plague. During the Khabarovsk War Crime Trials , the accused, such as Major General Kiyoshi Kawashima, testified that, in 1941, 40 members of Unit 731 air-dropped plague -contaminated fleas on Changde . These operations caused epidemic plague outbreaks. Substantial research has been done regarding
