The Pandemic of War and Flu, famine and bubonic epidemics contributed to making the 536AD worst year alive
The wars and pandemics of influenza, famine and bubonic epidemics have contributed to making the living worst 536.
Research by Harvard professor says the 536AD is the primary candidate for the unfortunate award of the worst year in history.
Earlier this year, the Middle East, Europe and parts of Asia were struggling with 18 months of complete darkness caused by mysterious fog.
It caused snowfall in China, plant failure on a continental scale, extreme drought, hunger and disease in most of the northern hemisphere, the Daily Mail reported.
A harsh year caused a cataclysmic Icelandic explosion, according to scientists.
Harvard archaeologist and medieval historian Michael McCormick for the science journal Science knew that the world did not show signs of recovery until 640.
He said, "It was the beginning of one of the worst periods if he was alive, if not the worst year."
The effects on the climate were so difficult that the Irish chronicles talk about "the failure of bread from 536-539".
Temperatures in summer 536 dropped between 1.5 ° C and 2.5 ° C, making it the coldest decade in the past 2300 years.
Historians have long known that in the middle of the sixth century there was a dark hour called Dark, but the source of mysterious clouds has long been a puzzle.
McCormick and glaciologist Paul Mayewski at the University of Maine's Climate Change Institute believe they found it.
At a seminar in Harvard this week, the team reported that a catastrophic volcanic eruption in Iceland was burning ash in the northern hemisphere at the beginning of the 536's.
Then there were two more massive explosions in 540 and 547.
Repeated wounds, followed by death, plunged Europe into economic stagnation, which lasted until 640.

It is believed that volcanic activity produced millions of tons of ash, which spread throughout large parts of the world.
Leads in the ice core of lead have shown that melting takes place in order to create silver and this coincides with the arrival of coins that helped revive the economy, says archaeologist Christopher Loveluck of the University of Nottingham.
Scientists have discovered that a century later in 660, silver became a coin choice.
