So looking back on 2018, some people didn't have a good time. A great article puts things in perspective. I tried to edit it to one post but it looks like it'll have to be 2.
Suck it up, everybody: Here are nine years infinitely worse than 2018 - You may be broke and miffed by Trump, but at least your entire civilization isn’t crumbling around you
1347 - The Black Death killed roughly one fifth of the world population, and up to sixty per cent of everyone in Europe. Panicked citizens who blamed the Jews for the plague would even launch a miniature Holocaust, razing thousands of European Jewish communities. The carnage of the Black Death was so overwhelming that, like many on this list, the people of 1347 feared that future generations (should they exist) would never believe that the plague had actually happened.
1942 - At the beginning of 1942, most of the Holocaust’s six million victims were still alive. By year’s end, death camps were opened across Europe and millions lay in mass graves, executed by genocidal death squads following the Wehrmacht’s advance into the Soviet Union. In a merciless response to the first U.S. air raid against Tokyo, Imperial Japan massacred whole villages in coastal China, killing 250,000 Chinese by year’s end. And the year would end in the freezing chaos of the battle of Stalingrad, the largest confrontation in the history of warfare.
1520 - European contact had not been good for the Indigenous people of the Americas. But 1520 was when European contact would truly begin to wipe whole peoples from the map. Smallpox took hold for its major New World outbreak in 1520, unleashing the epidemiological equivalent of nuclear war on the Western Hemisphere. At the beginning of 1520, the population of current-day Mexico was about 20 million. By year’s end, up to eight million were dead or dying.
536 - This is the year that Harvard historian Michael McCormick has definitively pegged as the “worst year to be alive.” A volcanic eruption forced the entire world under ashen skies, kicking off the coldest decade in more than two millennia. The sun was so obscured by pollution it was possible to stare directly at it. Then, only five years later, the Plague of Justinian killed up to one quarter of whoever was left. Grinding poverty was already the norm in 536, but that year saw much of humanity descend into a generation or two of particularly acute misery.
1816 - The Year Without a Summer. China was racked by starvation after losing much of its rice crop. Heavy rains in India incubated a devastating cholera epidemic. Europe suffered its last widespread famine, and oat shortages killed so many horses that a German baron was compelled to invent the bicycle. The culprit for all this was the eruption of the Indonesian volcano Tambora, which enshrouded the planet in a thin layer of sun-blocking ash.
