Igor Karkaroff
Karkaroff is a former
Death Eater. He was captured by
Auror Alastor Moody after the fall of
Lord Voldemort. Moody is responsible for Karkaroff's imprisonment in
Azkaban.
Later, the
Ministry of Magic released him from Azkaban in exchange for the names of other Death Eaters. While some of the names he provided were useless (Death Eaters who were dead or arrested), he traded information for his freedom.
Karkaroff went on to become Headmaster at Durmstrang. During his time there, actual Dark Arts are said to have been studied by the students of Durmstrang (instead of just defence against them). Moreover, Durmstrang was only open to pure-blooded wizards and witches. It is not known how much of this was Karkaroff's direct influence to Durmstrang and how much existed before his tenure.
Karkaroff was seen to show exceptional favouritism towards his most famous student, Bulgarian
Quidditch player
Viktor Krum.
In
book 4, Durmstrang entered the newly-revived
Triwizard Tournament with
Hogwarts and
Beauxbatons schools. As headmaster, Karkaroff was a Triwizard judge. After the unexpected inclusion of a second Hogwarts champion,
Harry Potter, Karkaroff was angry and threatened to drop out of the Tournament.
During the course of the year he met fellow ex-Death Eater
Severus Snape, with whom he shared several conversations regarding past events. In June 1995, at the end of the Triwizard Tournament, Karkaroff went into hiding after sensing the summons of
Lord Voldemort. According to Viktor Krum, Karkaroff did not steer the Durmstrang ship moored in the Hogwarts Lake but rather let his students do all the work. It is not known who took over Durmstrang in his place as headmaster, but in
Harry Potter and the Order of the Phoenix,
Hermione Granger mentioned that the school's reputation had suffered greatly after it was learned that Karkaroff was a Death Eater.
After his return, Voldemort made a comment referring to making a certain one of his cowardly Death Eaters pay for his disloyalty. In
Harry Potter and the Half Blood Prince,
Remus Lupin mentioned that Karkaroff had been found dead in a shack with the
Dark Mark hovering over it, indicating he was killed by Death Eaters. This strongly suggests that it
was he who was referenced in Voldemort's declaration. Lupin considered it impressive that he survived for a year after deserting Voldemort.
Igor Karkaroff's nationality is uncertain. He speaks without a foreign accent, but the Durmstrang winter clothing, consisting of fur capes, appears to be a reference to traditional Nordic clothing most often associated with Russian
Ushanka headdress. His full name is Slavic, however it is fictional and points to him being a generic "Eastern foreigner", rather than to any specific country. The first name "
Igor" is very uncommon outside
Russia,
Ukraine and
Belarus, being a
Slavic version of Scandinavian "Ingvar" and appearing in history as early as 9th century AD. "Karkaroff", on the contrary, is a variation of a
surname that is most likely to be encountered in
Bulgaria, and Slavic last names are usually transcribed with the last "ff" in German-speaking countries. It is unknown to what extent Death Eaters are active outside of the
UK; though Rowling has defined their goals as being "European", she has never mentioned if Voldemort has plans in Continental Europe. As he was tried (and presumably caught) in the United Kingdom, he may have been active there, no matter what country he is from.
In
Harry Potter and the Goblet of Fire, Karkaroff is described as being a neat, fussy-looking man with an oily voice and manner who sports a small grey goatee. While unctously pleasant most of the time, he is capable of violent rage.
In the film version of
Harry Potter and the Goblet of Fire, Karkaroff shown as a bearded, fur-clad man with a striking resemblance to the depiction of
Ivan the Terrible in
Sergei Eisenstein's
film. He also resembles
Grigori Rasputin, a
Siberian, who like Karkaroff was reputed to be a master of supernatural powers who held ambivalent or equivocal alliances. Karkaroff's accent in the film and his behaviour — particularly the affectionate bearhug he bestows upon
Albus Dumbledore — indicate that he was depicted as an archetypal
Russian.
