account is full ofcrummy times . Flip to any chapter in the human level , and you ’ll regain that peace and successfulness are the exception , not the norm . indisputable , periods of plenty and politeness have been enjoyed , but they often camecrashing downin anoutbreak of violenceor , if you were favorable , they slowly rotted away into obscurity . However , of all the times to be alive , one year is particularly striking in the chronicle of misery : 536 CE .

This era was low – not just because of bloody wars or furious diseases , but due to a volcanic eruption that cast ash tree and junk into the sky , cloaking the Lord’s Day with a soft , gray haze .

Nobody is entirely sure which volcano was responsible , although El Salvador ’s Ilopango has long stood as a top competitor . However , astudy in 2018put forward-moving evidence that the outbreak was in Iceland , as ice burden in Europe contain volcanic glass that ’s chemically alike to particles find across Europe and Greenland . It isalso possiblethat the so - called “ volcanic wintertime ” was actually trigger by an unfortunate serial of volatile eruptions around 536 to 540 CE .

Whatever the volcanic culprit , its effects were dramatic . In a alphabetic character publish in 538 CE , Roman national leader Cassiodoruswrote : " Men are alarmed , and by nature alarmed , at the sinful sign in the heavens , and ask with unquiet tenderness what event these may foretell . The Sun , first of stars , seems to have mislay his wonted light and appear of a blueish color . ”

" We marvel to see no shadows of our bodies at noon , to feel the mighty heartiness of his heating waste into feebleness [ … ] The Moon , too , even when her orb is fuelled , is empty of her innate brilliance . ”

Procopius , a Byzantine historian living in the Middle East at the time , also wroteof " apprehensiveness " stimulate by a dazed eclipse of the Sun .

There ’s plenty of strong-arm , scientific evidence of this phenomenon , too . tree cut down in Denmarkshowextremely narrow ontogenesis ring during the mid - 6th century due to “ drastic climate change ” that occurred in 536 CE , while crank core from Greenland and Antarcticahighlightevidence that the atmosphere was clogged with an “ extensive atmospherical acidic junk veil ” during this time .

Amid the darkness , temperatures plummeted in the Northern Hemisphere and husbandry crumple . Scholars believe the eruptions of 536 CE may have been linked to the start of the Late Antique Little Ice Age , which pop out that very class and was consolidate by more eruptions around 540 and 547 CE .

summertime temperatures around the worldfell by several degrees , and Earth ’s climate was profoundly shaken up . Snow fell during the summer in China , droughts strike South America , and the deathly haze in the sky was fret about in the Middle East .

of necessity , dearth and miserableness quickly followed . Gaelic Irish annals talk of " a loser of bread in the class 536 [ CE ] , ” while bubonic plague swept through the Romanist port of Pelusium in Egypt .

This was nearly 1,500 year ago , so we do n’t have the welfare of societal media to chronicle the intact world ’s angst , nor even much direct documentation , but many historiographer concur that the class 536 CE marked the beginning of a particularly unrelenting chapter in human story , at least in some regions of the creation .

In Europe and parts of Asia , the year 536 CE “ was the beginning of one of the worst periods to be alive , if not the worst yr , " Michael McCormick , a knightly historiographer and archaeologist who chairs the Harvard University Initiative for the Science of the Human Past , toldSciencein 2018 .

Within five years of the onset of the Late Antique Little Ice Age , theJustinianic plaguepandemic swept through the Mediterranean . Constantinople , the warmness of the Eastern Roman ( Byzantine ) Empire , was especially hard - murder and millions of people cash in one’s chips over the following decades . While multiple factor contributed to the empire ’s eventual flop many century later , somescholars arguethat this deadly combination of mood tragedy and pandemic played a pivotal character in ending its glory 24-hour interval .

The ripple effects extend far beyond the Mediterranean . In the tank , drier conditions of central Asia , dwindle pasture ram several roving tribes to migrate eastward toward China . This motion activate clank between these migrating grouping and local baron in the steppe region of northerly China . In a surprising twist , some of these steppe kindred afterward formed alliances with the Eastern Roman Empire . Together , they helped bring down the Sasanian Empire in Persia .

However , perhaps the volcanic wintertime of 536 CE was n’t such bad tidings for other section of the world . As the Eastern Roman Empire and Sasanian Empire suffered , the Arabian Peninsula became blessed with more rain .

With the old empires in trouble , the Arabian Peninsula – now slightly immature than in former centuries – was poise to become the stage for a Modern power to heighten . Andrise it did . Amid many other factors , the Arab Empire sprang onto the world stage by the 7th hundred CE , rapidly becoming one of the most powerful and influential forces in chronicle .
