Ivan the Terrible questions:

Questions about the Ivan IV readings:

What was the significance of the oprichniki’s “brushes or brooms tied on the ends of sticks”?  When does this look like?

Why did Ivan kill everyone and plunder instead of taking over the lands to become more of a monarch of sorts?

On page 153 (second paragraph), it states Ivan accepts all the petitions that were being maintained for the oprichniki.  What was his motivation to do this?  Did he suspect foul play was involved?
