Pogroms
I've researched about pogroms before, and thought it would be appropriate for this topic.
It was very harsh treatment of the Jewish population in Russia by the Russian Empire at the time.
The first registered pogrom was in 1821, in Odessa. Many Jews were harassed, and then beat up, while many others were killed in the process of this rioting.
These events make me feel "oh not this stuff again," because it is just one more piece in the violent history behind the Jews and what they have been through. Reading the details and watching the paintings made about these incidents is shocking and disturbing, to the point where I do not want to read it anymore, or even think about it.
