Its a historical fact in Hungary that she was a victim of conspiracy, charged to strip off all her wealth and name, having only testimonies from torturing her closest servants and paid witnesses from other counties. Its in our history books.
Vlad Țepeș however.... Yea he was a fucked up person.
Don't take things in those books as "facts" because it is a fact that details are skewed and written over what really happened via "History Written By The Victors" as it were.
(Basically it's not a straight fact for being possibly rewritten as to how it may have actually gone.)
