Early Years Edit
During his childhood as the Imperial Crown Prince and the heir apparent to the Imperial Golden Lion Throne, Shaddam became close friends with his maternal cousin, Count Hasimir Fenring who became his closest friend.
Ascent to the Throne Edit
In year 10156 AG, Shaddam succeeded his father as the 81st Padishah Emperor and head of Imperial House Corrino, after Elrood IX succumbed to chaumurky. A frequently discredited history of the Corrinos detailed a story that Count Fenring was responsible for poisoning Elrood.
- Irulan Corrino — The eldest daughter of Shaddam and Anirul, and the Imperial Crown Princess and the heiress apparent to the Imperial Golden Lion Throne of the Galactic Padishah Empire.
- Chalice Corrino — The second daughter of Shaddam and Anirul, who died unexpectedly on Kaitain or Salusa Secundus.
- Wensicia Corrino — The third daughter of Shaddam and Anirul, and the former Sovereign Co-regent of the Imperial House Corrino.
- Josifa Corrino - The fourth daughter of Shaddam and Anirul, and the Bene Gesserit Truthsayer of the Landsraad.
- Rugi Corrino - The fifth and youngest daughter of Shaddam and Anirul, and the last Princess of the Imperial House Corrino.
Shaddam's lack of legitimate sons ensured that he was the last ruler of House Corrino.
His wife Anirul died in 10176 AG.
The Atreides and the Fall of the Corrino Empire Edit
The events leading up Shaddam's fall from power were triggered by the Emperor himself. He reportedly felt threatened by his adoptive cousin, Leto Atreides I, the Duke of House Atreides. This was because Leto was a charismatic and honourable man, and had become very popular in the Landsraad. Moreover, Leto had managed to train a small army under Thufir Hawat, Gurney Halleck and Duncan Idaho well enough to rival the Sardaukar. Consequently, the Emperor conspired with House Harkonnen, long time rivals of House Atreides.
In secret, however, Shaddam admired his cousin Leto, and had once mentioned to Irulan that he had wished the political climate that necessitated animosity toward the Atreides did not exist. Moreover, Shaddam had secretly wished that Irulan had been old enough to marry Leto, both because he knew Leto to be an honourable and just man who possessed the love of his people, but also because he would have been an ideal choice for succeeding him, especially since Shaddam had no direct male heirs.
Despite his personal feelings for Leto, Shaddam pressured Leto to surrender the fief of his native planet Caladan to Count Hasimir Fenring, and to take over the administration and spice mining operations of Arrakis. House Atreides took control of Arrakis in 10,191.
However, shortly after Leto took control of Arrakis, he and most of his army were soon slain as a result of a combined invasion by Sardaukar and Harkonnen forces. The attack was a success, and Shaddam considered the threat posed by House Atreides to have ended. However, the Lady Jessica, and more importantly her son Paul Atreides survived. They were given sanctuary by the Fremen and as a result of their skills, they eventually rose to their leadership.
By the year 10193 AG, the young Duke had managed to lead the Fremen in a battle that defeated the Harkonnen and Sardaukar forces on Arrakis. As a result, they were able to halt the melange trade. Shaddam IV was forced to step down from the throne, and thus end his reign of forty years, and the Imperial reign of House Corrino that had lasted ten thousand years.
In 10196 AG, Shaddam was exiled to his ancestral planet of Salusa Secundus along with his four younger daughters and Count Hasimir Fenring. Princess Irulan Corrino was named Sovereign Co-regent, but Paul Atreides effectively ruled as Emperor as her husband. Shaddam Corrino IV died in year 10202 AG at the age of 68.
