"Today is the end of the Republic! The end of a regime that acquiesces to disorder! At this very moment, in a system far from here the New Republic lies to the galaxy while secretly supporting the treachery of the loathsome Resistance. This fierce machine which you have built, upon which we stand, will bring an end to the Senate! To their cherished fleet! All remaining systems will bow to the First Order! And will remember this... as the last day of the Republic!"
General Armitage Hux[src]

The Hosnian Cataclysm, also known as the destruction of Hosnian Prime or the destruction of the Hosnian system, was the destruction of the Hosnian system at the hands of the First Order thirty years after the Battle of Endor. The event took place during the Cold war and marked the annihilation of Hosnian Prime, the capital of the New Republic. Its destruction was carried out by Starkiller Base, a superweapon capable of destroying entire star systems. With the destruction of Hosnian Prime came the destruction of the Galactic Senate and part of the New Republic Defense Fleet. The massive sub-hyperspace ripple created by the destruction of the system caused the event to be visible in real time around the galaxy, including the planets of Takodana and Vardos.

Though stunned by the events, the armed forces fighting the First Order, commanded by General Leia Organa, immediately began their response. The Resistance successfully destroyed the Starkiller weapon, ensuring it would never eliminate another star system again. However, the extermination of the Galactic Senate and a large part of the Republic Starfleet, as well as the massive loss of life, left both the New Republic and the Resistance in a vulnerable position.


"The weapon. It is ready. I believe the time has come to use it. We shall destroy the government that supports the Resistance, the Republic. Without their friends to protect them, the Resistance will be vulnerable, and we will stop them before they reach Skywalker."
―General Hux, to Supreme Leader Snoke[src]

The First Order constructed Starkiller Base, and with it intended to destroy the New Republic.

At the end of the Galactic Civil War, the Galactic Empire was left defeated by the New Republic, the government formed by the Alliance to Restore the Republic after the death of the Emperor during the Battle of Endor. The Empire officially signed a treaty, the Galactic Concordance, with the Republic,[5] keeping the remnants of the Imperial confined to their territories in the Core Worlds and the Inner Rim.[6] What remained of the Imperial Starfleet, however, retreated into the Unknown Regions and ultimately formed the First Order, a successor force with the goal of destroying the New Republic and bringing order to the galaxy. As part of their plan, the First Order built a fleet in the shadows of the Unknown Regions and constructed a new superweapon called Starkiller Base, one capable of destroying entire star systems. The construction of the Starkiller weapon marked the culmination of efforts by the Old Empire to research dark energy translations and hyperspace tunneling,[5] and it was a successor to the Death Star and the Death Star II superweapons that came before it.[1]

During the conflict that had only just begun to spark between the First Order and the Resistance, Supreme Leader Snoke, the leader of the First Order, considered Luke Skywalker to be an existential threat to the designs of the First Order. Snoke believed that if Skywalker, the last of the Jedi, returned from the exile he imposed on himself after the destruction of his new generation of Jedi and aided the Resistance, a new Jedi Order could arise to threaten him. Kylo Ren, apprentice to Supreme Leader Snoke, attempted to find the last piece of a map that they needed to locate Skywalker, but his efforts at first proved unsuccessful. General Armitage Hux, commander of the Starkiller, argued in favor of using the weapon to destroy the Republic and eliminate the government he believed was illegitimate and ill-equipped to lead the galaxy. Hux argued that without the Republic, the Resistance would no longer be a threat. Snoke agreed and gave his permission to fire the weapon.[1]

Starkiller Base fires its weapon

On Snoke's command, Hux prepared the Starkiller weapon to be fired against the Hosnian system[1] in the Core Worlds, the capital of the New Republic.[5] When the weapon was ready, Hux addressed the legions of stormtroopers under his command who assembled to witness the destructive firepower of the weapon. Hux promised that this day would be the end of the New Republic and ultimately, the Resistance, the culmination of everything the troops had worked towards. Hux then commanded that the weapon be fired, and massive beams of energy were fired across the galaxy towards the Hosnian system. When they arrived, the astronomical bodies of the system were destroyed, including Hosnian Prime.[1][5] With the destruction of Hosnian Prime, the capital planet of the Republic,[5] came the destruction of the Galactic Senate and much of the New Republic Defense Fleet. The casualties on Hosnian Prime included Chancellor Lanever Villecham and Korr Sella, an envoy from the Resistance sent by General Leia Organa to warn the Senate about the threat of the First Order—a warning that came too late.[1][5]

The firing of the Starkiller weapon released sufficient energy to create a temporary rip in sub-hyperspace.[7] This caused the destruction of the Hosnian system to become visible from across the galaxy, causing terror and shock on countless worlds who had no idea of what was happening. The famed smugglers Han Solo and Chewbacca, along with stormtrooper defector Finn, witnessed the system's destruction from Takodana, in the Inner Rim. The sight led to confusion on Takodana, but Finn told Solo and Chewbacca that what they were seeing was the First Order using the Starkiller to destroy the Republic capital.[1] Ex-Imperial and member of Inferno Squad Iden Versio also witnessed it from her home planet of Vardos. Resistance member Shriv Suurgav, who was also present, immediately knew that it was the First Order but was unable to work out what they had done until they were captured by First Order officer Gideon Hask; while Shriv was staggered and horrified, Hask referred to the system's destruction as a thing of beauty.[3]

The Resistance launches an attack against Starkiller Base, leading to the weapon's destruction.

After the destruction of the Hosnian system, the Resistance put a plan in motion to destroy the Starkiller before it could destroy D'Qar, the world the Resistance called home. Finn, Solo, and Chewbacca were sent to the weapon first to disable its shields, while Commander Poe Dameron led a starfighter assault against the base's thermal oscillator, which contained the energy that it drained from stars in order to power its weapon. The Resistance forces were able to successfully destroy the weapon but at the cost of a number of Resistance lives, including Solo and many starfighter pilots.[1]

The Hosnian Cataclysm led to a complete shift in the galactic status quo. Although the New Republic had never had the size or influence of the Galactic Republic at its height, it had been the dominant galactic power since the Battle of Jakku. Now, with its political structure decimated and its important fleet in ruins, the First Order had established itself as the primary power in the galaxy, with resources sufficiently important to conquer it. Systems and planets across the galaxy, that had been tempted by the First Order's promises of security, instantly capitulated, while several others were taken by conquest. In the Resistance's estimate, the First Order would seize the Core Worlds in a matter of weeks.[8][9]

Behind the scenesEdit

The destruction of the Hosnian system was depicted in the 2015 film Star Wars: Episode VII The Force Awakens.[1] It was suggested by Pablo Hidalgo, creative executive of the Lucasfilm Story Group, that the reason the blast from Starkiller Base could be immediately seen from Takodana was due to a "sub-hyperspace rip side-effect" of the Starkiller.[10]
