Daniel Coleman, 22, of Chaddesden also was ordered to stay away from the woman and her family for the rest of his life, the Derby Telegraph reported Monday.
Coleman was given a 4 1/2-year sentence after pleading guilty to a series of stalking actions, dating to 2008, that included sending the unnamed woman's mother an altered videotape implying the beheading of the woman and her sister with an axe, sending the woman threatening Facebook posts and a letter threatening to burn down her house, and scrawling her name, with insults, on her home and other local buildings, the newspaper said.
Derby Crown Court was told by prosecutors when police raided Coleman's home they found photographs of Coleman dressed in Nazi military attire, and that he had "a preoccupation with Germany, Austria and National Socialism."
Julia King, the attorney for Coleman, described her client's actions as "an appalling catalogue of incidents but there was no actual violence."
But Recorder John Aucott said Coleman's actions were deserving of the maximum penalty he could impose.
"You are not mad, you are bad," Aucott said.
"In 14 years, this is the first time I have handed anyone who has come before me the maximum sentence I am allowed to."
