Saw a great video a few months back that was very informative. I realize this video is not exactly what you are looking for and there are qualified people here that could give better help however it is relevant to your topic and feel it could give you some other information (names, locations, events, etc) you could use to further your research. It is by the youtube channel Caspian Report and its about the creation of the Russian Mindset. It gives great information on the conflicts that gave birth to modern Russia. At the 2:40 mark it mentions Ivan the Terrible how ever watch from the beginning to about five or six minutes in. Hope it can help in some way https://www.youtube.com/watch?v=HE6rSljTwdU
