Top Ten Worst Days In Human History

The reason why I believe 9/11 is the worst day in human history is because it came out of nowhere. Normally, people are able to see horrible events coming, but in the case of 9/11, it came out of absolutely nowhere. Most of America's major adversaries at the time were long gone, and no one knew who the perpetrators were. All they knew was that they were being attacked.
The thing about Sept 11th is it was so out of the blue and totally unexpected. It was very sick and extremely evil. Those terrorist murderers were twisted deranged monsters. There were babies and small kids on those planes who lost their lives for nothing. No one jumped from the building, they were pushed or they jumped rather than slowly burn in horrific heat.
Perhaps the worst day of my generation. Seeing thousands of lifes destroyed on live T.V. in disbelief and with impotence. This event further formed our world as it is, with the fear of terror, the abandonment of privacy and the endless war on terror with all its lost.
Without a question April 5, 2019. For me that was the evening of infamy after an evening of celebration the previous day. I was only trying to remove the safes and it turned worse than September 11, 2001. That day changed my life forever.

Truly a horrible day in history. Though I think 28 June 1914 could be considered worse. It marked the moment WW1 would be inevitable, which left millions dead, and the assassination of Franz Ferdinand would allow Hitler to rise to power and than start WW2. Still this day is one of the worst days humanity has seen.
Many innocent people died without a say or hesitation. Most died through horrific events. WWII is still the worst - and will be for a long time.
Sorry but this killed millions 9/11 killed only thousands which compared to millions isn't too bad sorry america.
To be honest, this day is worse than 9/11. More people were killed, plus this is when World War 2 started.

Horrible, horrible day. The day that Franz Ferdinand was shot, leading to World War I, World War II, the Cold War, the rise of communism and fascism, the indirect deaths of 50-100 million, the creation of the atomic bomb, need I say more? This day sucked.
Directly caused World War One and Two. Arguably marked the end of the empire and monarchy, that had been around since humans first started agriculture.
This day changed the course for the entire 20th century. Why is 9/11 above this?
Started WW1 which resulted in WW2 and cold war any many deadly conflicts after.

It was the start of the actual holocaust!

Either we risked losing even more of our men, taking over island after island, we get ROC and the Communist Chinese to work together, or we end the war in only a week. It was the best choice.
140,000 lost their lives in the atomic bombing of Hiroshima. Statistically, the number one worst single mass killing in history.
Considered to be the start of the Cold War which terrorised civilians for over 40 years.
Hitler was in it come on

It brought the United States of America to the war (which was a good thing) but we lost hundreds of people that day to people of which we did nothing (severely) wrong.
Bad for the United States, but a good day for the rest of the free world.
The day Pearl Harbour was bombed. So many innocent people died...
A day that will live in infamy.
For anyone wondering, the event referred to on this list is a series of Islamic terrorist attacks that happened all around the globe. Over 400 people died in a series of bombings and shootings. Unfortunately, June 26th, 2015 is also shared with groundbreaking civil rights laws that prevented the prohibiting of same sex marriage, and it's understandable why some people are confused and think people believe that same sex marriage is a tragedy.
Terrible day indeed
Stupid day for sure

This started the worst decade in recent history that affected the world (although some were hit harder than others). Millions lost their jobs, & most who didn't lose theirs still had horrible jobs with low pay. Like somebody said, many had to give up everything just for food, with one woman being forced to sell her children. This also led to Hitler's rise to power, as if the economy hadn't dived down significantly, he wouldn't have blamed Judaism for the collapse of Germany's economy (along with their WW1 defeat). So this day led to the 1930s being the worst decade in recent memory & led to the deaths of more than 83 million.
The Great Depression caused many people to sell all their possessions and sadly a women had to sell her children.

This was the day two teenagers shot up Columbine High School killing 13 people and injuring many others before committing suicide inside the school's library.
Horrible event, I would go so far to say this is worse than 911 but I can't expain why.
This happened nine days after I was born!
Columbine high school massacre.

The day a 20 year old burst into Sandy Hook Elementary in Connecticut and killed 20 first grade children, 6 staff members and even his own mother before killing himself inside a classroom.
I hate that this evil, evil man. He could've fixed HIS problems by getting help, or going to therapy. Instead, he made everything worse. May those children rest in peace.
Adam Lanza got what was coming, killing a whole classroom full of little kids is unforgivable, no matter how hard you apologise.
It's unbelievable that that disgusting evil jerk had the heart to shoot little kids in a school. I'm glad that he shot himself.
The Newcomers
November 24, 1859 was one of the worst days in history, because that was the day when the fairytale infamously known as Darwinian Evolution was created, and the worst fictional book ever known as origin of species was released that day. Darwinian evolution has deceived a lot of people.

I just want to burn this day to the ground, then throw it into a corpsegrinder and then puke all over it. Then I want to tie it to a rocket ship and I hope it gets hit by an asteroid and then has a fun time burning in the deepest depths of the bottomless lava pit. This day was so far beyond horrible for me that I would feel bad for the worst person in history if he had to endure it.
I guess that was when Ross Parks got arrested for sitting in the "white only" section of a bus.
I was just sad this day
The day the Titanic sank into the Atlantic Ocean after hitting an iceberg causing thousands to die on board. I am pretty sure the designers of the Titanic didn't even care about how many lifeboats they would have put on the ship.
After learning about this in history, I decided to never go on a cruise ship in my entire life.
When the Titanic sank, shocking the whole world forever.
The Boston bombing was pretty bad. A very bad day indeed.
Armenian Genocide... It happened a century ago during which over 1.5 million Armenians were killed and many countries still deny it... #StopTheDenial #We'llNeverForget
