The Cambodian genocide, under the Khmer Rouge regime led by Pol Pot, unfolded between 1975 and 1979. It resulted in the deaths of an estimated 1.7 to 2.2 million people, approximately a quarter of Cambodia’s population at the time.

The Mount Toba eruption, occurring around 74,000 years ago in Sumatra, Indonesia, was one of the largest volcanic events in history. It released massive amounts of volcanic ash and gases, causing widespread devastation and potentially triggering a global cooling event. Some scientists theorize that the eruption may have affected human populations, leading to population declines and environmental changes. Despite its catastrophic impact, life eventually rebounded, highlighting the resilience of the planet and its ecosystems in the face of natural disasters.

There were tons of animals with radically different “body plans” that went extinct. All kinds of radial symmetries (think starfish) and weirder things…most large animals today are descended from very few surviving body plans, especially the four-finned fish with forward-facing eyes that became most mammals.”

The Great Dying, also known as the Great Permian Extinction, was the most severe extinction event in Earth’s history, occurring approximately 252 million years ago. It resulted in the loss of over 90% of marine species and approximately 70% of terrestrial vertebrate species. The cause of this catastrophic event is still debated but is believed to be linked to massive volcanic eruptions, climate change, and ocean acidification. The Great Dying reshaped life on Earth, paving the way for the rise of new species and ecosystems in the aftermath of devastation. Its impact underscores the fragility of life and the profound influence of environmental changes on the planet’s biodiversity.

The volcanic winter of 536-538 occurred across various regions of the world, with significant impacts felt in Europe, Asia, and the Americas. While the exact location of volcanic eruptions triggering this event is still debated among scientists, evidence suggests that volcanic activity in places like Iceland, North America, and possibly Indonesia contributed to the atmospheric disturbances. The resulting darkness and climatic disruptions affected agriculture and ecosystems globally, leading to widespread crop failures, famine, and loss of life in many parts of the world.

The destruction of the Library of Alexandria is a symbol of the loss of ancient knowledge and scholarship. Founded in the 3rd century BCE, the Library of Alexandria was one of the most renowned centers of learning in the ancient world. It housed countless scrolls, manuscripts, and texts from various civilizations, covering a wide range of subjects including philosophy, science, mathematics, literature, and more.

The exact circumstances of its destruction remain a subject of debate among historians, but it’s generally believed to have occurred over several centuries rather than in a single catastrophic event. The library may have suffered damage from fires, wars, and political unrest, resulting in the gradual decline of its collection and influence. Nevertheless, the burning of invaluable texts and the decline of the Library of Alexandria are mourned because they represent the loss of a treasure trove of knowledge accumulated over centuries. The destruction of such a significant institution is seen as a setback for human progress and a reminder of the fragility of knowledge in the face of historical upheaval.

#10 Holodomor: Stalin’s Man-Made Famine

The Holodomor was a devastating famine that occurred in Soviet Ukraine from 1932 to 1933. It was orchestrated by Joseph Stalin’s regime as a result of his policies of agricultural collectivization and grain requisitioning. The Soviet government forcibly seized grain from Ukrainian farmers, leading to widespread starvation and death. Estimates of the death toll vary, but it’s believed that millions of Ukrainians perished as a result of the famine. The term “Holodomor” itself means “death by hunger” or “to kill by hunger” in Ukrainian. It’s widely recognized as a man-made tragedy and a deliberate act of genocide aimed at the Ukrainian people.

Leopold II of Belgium’s atrocities in the Congo Free State, his personal colony from 1885 to 1908, were characterized by brutal exploitation and violence against the indigenous population. Under Leopold’s rule, millions of Congolese were subjected to forced labor, mutilation, and mass killings in pursuit of rubber and ivory profits. The atrocities inflicted by Leopold’s agents resulted in widespread suffering and death, with estimates suggesting that millions perished as a result of his policies. Leopold’s reign of terror in the Congo stands as one of the darkest chapters in colonial history, highlighting the inhumanity and greed of European imperialism.

#12 The Third Crusade and Byzantine Destruction

“I don’t think I’m very wrong in saying that every human currently in existence has been impacted by this single event. One pompous aristocrat led the obliteration of a (literal) 1000-year-old city. The original Ba Sing Se. The city that endured a thousand conquerors. The literal crossroads of the East and West – political, religious, economic, intellectual – you name it. This was the real cause of the intellectual dark ages in Europe and the West, and I will die on this hill.”

Reflecting on the repercussions of the Third Crusade, users lamented the destruction of Byzantium and its profound impact on human history. The fall of Constantinople disrupted the cultural, political, and intellectual balance of the Eastern and Western worlds, leaving an enduring legacy of conflict.

#13 Atomic Bombings of Hiroshima and Nagasaki

#14 White Australia Policy: A Legacy of Discrimination

“Probably less well known outside of Australia, but in the early days of Australia becoming a country, politicians didn’t like the natives (aka. Aboriginals). So, as a way to get rid of them, they basically decided to breed them out, in what was called the white Australia Policy, which also included not letting people outside Europe enter the country.

Basically, all the aboriginal kids were taken away to live in white homes, and then they were to breed with white people until no trace of aboriginal DNA could be seen on the offspring. This is known as the stolen generation by Aboriginals. This, of course, didn’t work, and Aboriginals still exist, but it’s just horrible.”

The White Australia Policy, aimed at excluding non-European immigrants and assimilating Indigenous Australians, reflected entrenched racism in early Australian politics. Users expressed outrage at the forced removal of Indigenous children and the systemic oppression endured by Aboriginal communities.

#15 Queen Victoria’s Reign: A Legacy of Tragedy

“Queen Victoria’s reign. 100 million dead South Asians. 1 million dead Irishmen. Her 64-year reign dwarfed Hitler, Stalin, Mao, and Pol Pot’s death counts combined.”

During her long reign, Queen Victoria’s era was marked by immense suffering, including famines in South Asia and the devastating Irish Potato Famine. Users reflected on the staggering death toll under her rule, underscoring the complexities of historical legacies.
