Sheev Palpatine was born in 84 BBY and died in 35 ABY.
Sheev Palpatine, secretly the Sith Lord Darth Sidious, was a human politician from Naboo who rose to become Supreme Chancellor of the Galactic Republic and ultimately Emperor of the first Galactic Empire. Trained in the dark side by Darth Plagueis, he cultivated dual identities — the affable public senator Palpatine and the shadowy Sith master Sidious — using both to engineer the galaxy's collapse. He manipulated the Trade Federation's blockade of Naboo to win the chancellorship, orchestrated the Clone Wars from both sides, and used the conflict as a pretext to purge the Jedi Order through Order 66 and declare himself Emperor in 19 BBY. He ruled the galaxy through fear and the dark side until he was cast down by Darth Vader at the Battle of Endor in 4 ABY. Yet Sidious cheated death: having prepared cloned bodies and a hidden cult on Exegol, he returned decades later, only to be finally destroyed by Rey and the combined spirits of the Jedi in 35 ABY. He is remembered as the galaxy's greatest villain and the architect of the Republic's fall and the Empire's rise.
Sheev Palpatine is born into an aristocratic family in Theed, the capital of Naboo.
As a young man, Palpatine is discovered and taken as the Sith apprentice of Darth Plagueis, becoming Darth Sidious and learning the ways of the dark side while building a political career.
Palpatine establishes himself in public life, eventually representing Naboo as its senator in the Galactic Senate on Coruscant.
Following the Rule of Two, Sidious kills his master Plagueis in his sleep, becoming the reigning Sith Lord and taking his own apprentice, Darth Maul.
Sidious orchestrates the Trade Federation's blockade and invasion of Naboo, using the ensuing crisis to have Chancellor Valorum ousted and to be elected Supreme Chancellor of the Republic.
Manipulating the Separatist crisis through his apprentice Count Dooku, Palpatine is granted emergency powers as the Clone Wars erupt, secretly commanding both the Republic and Separatist forces.
Palpatine prolongs the galaxy-spanning war to consolidate power, erode the Senate, and set the Jedi Order up for destruction.
Sidious turns Anakin Skywalker to the dark side as Darth Vader, issues Order 66 to exterminate the Jedi, reorganizes the Republic into the Galactic Empire, and declares himself Emperor.
Emperor Palpatine rules through the Death Star and his apprentice Vader as the Rebel Alliance destroys the battle station at Yavin.
The Emperor directs Vader to hunt down Luke Skywalker, sensing the young Jedi's potential and plotting to turn him.
Aboard the second Death Star, Palpatine attempts to corrupt Luke, but Vader turns on his master and hurls him into the reactor shaft, killing the Emperor at the Battle of Endor.
Having transferred his essence into cloned bodies prepared on the hidden Sith world of Exegol, a weakened Sidious survives and builds the Sith Eternal cult and a secret armada while orchestrating events from the shadows.
Palpatine reveals his return and lures his granddaughter Rey to Exegol. Drawing on the strength of all the Jedi, Rey turns his own Force lightning against him, destroying Sidious and his cult once and for all.
