The group that committed violence against African American in the late 1800s and the early 1900s was white supremacists They are known by the KKK. Back in those days, they would lynch people by hanging.
Terrible
There was no Wifi, no AC, no popcorn, no instagram...
Haha just kidding. But seriously, it probably was terrible. 1066 was during the middle of the Dark Ages, and for a Jew/Muslim, it was the age of the first "Holocaust" or genocide of their people. 1066 was when Jews/Muslims were living peacefully in Jerusalem, and in 1096 Europe decided to kill them all...

There is no greater jump in human history in terms of warfare than the jump during World War I and the jump during World War II.
World War I marks the first major debut of killing technology onto the world stage. This included airplanes, chemical weapons, and more.
As a result, humans could kill or ruin the lives of other humans with brutal efficiency.
One of the biggest reasons for America back off their interventionist policy in Latin America was the Stock Market Crash of 1929 and the ensuing Great Depression. Once the Great Depression hit America, the government was far more concerned with how to help American citizens and how to help the economy recover rather than focusing on Latin American countries.
Along with this, the United States's entrance into World War II in 1941 also redirected their attention. The US was more focused on helping the Allied powers win in the Pacific and European theater rather than focusing on Latin America.
