However, when speaking of the worst year recorded in human history there are many to choose from:

The year 1349 saw the Black Death kill half the population of Europe.

In 1520 smallpox ravaged the Americas and killed between 60 and 90 per cent of the continents' original inhabitants.

In 1918 the Spanish Flu led to the deaths of over 50 million people.

The rise of Hitler in 1933 is often claimed to be the turning point in modern history.

However, historians are unanimous in their choice...

The title of the worst year in history is easily held by the year 536 AD.

Medieval historian, Michael McCormick has stated that:

"it was the beginning of one of the worst periods to be alive, if not the worst year."

- Science Magazine, Ann Gibbons, 2018

The year began with an inexplicable, dense fog that stretched across the world which plunged Europe, the Middle East and parts of Asia into darkness 24 hours a day, for nearly 2 years.
