Pius Thicknesse

Minister Pius Thicknesse was a British wizard and a Ministry of Magic official in the mid to late 1990s. During the Second Wizarding War, he became Head of the Department of Magical Law Enforcement as well as, later in the War, Minister for Magic under Lord Voldemort's puppet regime while under the Imperius Curse twice, and later became The Dark Lord's (both) puppet himself. He replaced Rufus Scrimgeour as Minister of Magic, who had been murdered by Tom Riddle, and later Hermione Granger temporarily, who fleed.

He was "impeached" following Tom Riddle's second and final death in 1998 and was succeeded by Kingsley Shacklebolt in his post of Minister for Magic.

In 2019, the Ministry fell again, but fortunately, several high ranking officials (such as Harry Potter) fled the Ministry and went into hiding. However, despite the "exhaustive defensive strategies" set by Pius Thicknesse (actually set by Voldemort), a revolt ensued. Christopher Lewis, wanting the location of Jason Malfoy, captured and brutally tortured Thickneese right in his office, though when Thickneese refused to speak the truth, Christopher assassinated him with the Killing Curse.
