I have laid out a very crude description of the purges. The article doesn't mention how disorganized and disorderly Yezhovshchina was and many other details. I have begun my research on this topic very recently, and I'm overwhelmed by the complexity of the subject.

If anyone can contribute to this subject but don't feel like creating an account, you can put what you know in a comment, or write paragraphs to be added in the comments, preferably with sources
