House Harkonnen: the Baron's Giedi Prime
the Great House of Giedi Prime
Seated on industrial Giedi Prime and ruled by a Siridar-Baron, the Harkonnens had hated House Atreides since Corrin. Arrakeen finished them off.
House Harkonnen, also known as the Family Harkonnen, was a Great House of the Landsraad whose capital lay on the heavily industrialized world of Giedi Prime. The historical enemies of House Atreides since the Battle of Corrin, the Harkonnens earned a notorious reputation for underhanded and sinister political tactics, fueled by ambition, malevolence, hatred, and brutality. Typically ruled by a Siridar-Baron, the House was essentially annihilated as a major political entity after the Battle of Arrakeen, though its bloodline survived. (Dune)
Rise to a Great House#
After the Bashar Abulurd Harkonnen was banished for cowardice following the Battle of Corrin, Harkonnen influence rose again within the Landsraad, owing mostly to adroit manipulation of the whale fur market and later to melange wealth from Arrakis. Baron Vladimir Harkonnen was a male-line descendant of Abulurd. The House built its power by maximizing production output while minimizing expense, ignoring economically ethical behavior. Harkonnen governing rested on a simple foundation of fear and terror, applied in the running of the household, in governance, and in the control of the Harkonnen armies. Within a social order based on treachery and punishment, soldiers rose through the ranks by deceit, trickery, and, where necessary, assassination. The climb took the Harkonnens into the ranks of the Great Houses, alongside their old enemies the Atreides. (Dune)
Rule over Arrakis#
When the story of Dune begins, House Harkonnen has held Arrakis for eighty years, as a quasi-fief under a CHOAM Company contract to mine the spice melange. Through persecution of the Fremen and through minimal outlay on infrastructure and pay, the Harkonnens paid the tithe owed to the Padishah Emperor while keeping a substantial quantity of melange for themselves. They amassed considerable wealth from the spice trade. (Dune)
In the game Dune II, Harkonnen armies fight the Atreides and the wealthy cartel House Ordos for this same spice fief. (Dune II: The Building of a Dynasty)
The plot against the Atreides#
Despite the House's relative power before the end of the Corrino Imperium, Vladimir Harkonnen sought the ultimate achievement of usurping the Corrinos and forming a Harkonnen Empire. He secretly plotted against both House Atreides and House Corrino, hoping to destroy the former and overpower the latter through force and marriage. When Duke Leto Atreides I was given the fief of Arrakis, the Baron sprang his trap, but his plans were ultimately unraveled by the rise of Paul Atreides on Arrakis. The Baron's nephews and his Mentat Piter de Vries all have places among the main Dune characters. (Dune)
Demise#
Following the Baron's death at the hands of Paul's younger sister, Alia Atreides, in 10193 AG, the House's hopes passed very briefly to his nephew and heir Feyd-Rautha Harkonnen before Feyd was killed by Paul Atreides in a duel. With the ascent of House Atreides, what little remained of House Harkonnen saw its power and resources quickly vanish. (Dune)
A surviving bloodline#
House Harkonnen ceased to be during the time of Muad'Dib's Jihad, yet the Harkonnen bloodline endured. It continued through the Bene Gesserit breeding program, and, through its mingling with the Atreides line, lived on most directly in Paul Atreides, who was the grandson of Vladimir Harkonnen. Giedi Prime itself survived under a new name, Gammu, where a hidden Harkonnen no-globe still stood some fifteen hundred years later. (Dune; Heretics of Dune)
