Unsettling Photos from History's Tense Moments
Our history is, sadly, full of very tense moments, where saying the wrong thing could have started another useless war. And we know this because a lot of wars started because someone said the wrong thing at the wrong time.
But even in times of peace, which aren't that many, political and diplomatic relations have been tense among some nations throughout history. So much so that it seems like that's the way they like it. From historical protests to terrible massacres, photojournalists have captured incredible moments before disaster that will chill your blood.
So, here are some unsettling photos from history's tense moments.
Police State

Last Public Execution by Guillotine

Incidents of Reinosa

Workers held the CEO of the company hostage the day he was getting a position in the government for being compliant and quiet during the layoffs, so tension was rising by the hour.

Little Rock Nine

White students yell at the Little Rock Nine outside Tuskegee High School in Montgomery, Alabama, after it had been integrated in 1963. Some of them regretted this later, not because they had a change of heart, but because the picture made the front page of many local newspapers, and they started getting hate mail, among other things.
Serra Pelada

Serra Pelada workers were protesting for better conditions when more than 500 soldiers were sent to clear the area. This photo was taken moments before what's known as the St. Boniface Massacre, referring to a local celebration of the saint on that day.
