Count Dooku
Once upon a time Count Dooku, (also known as Darth Tyrannus), was a Jedi, with Qui Gon Jinn and later Komari Vosa as his apprentices, but when he learned that Palpatine was in fact the Sith, he decided to join the dark side, just like Anakin did a few years later and from then he became a central Separatist leader and schemed many plots of deviousness including kidnapping Jabba the Hutt's son and framing the Jedi for it. He also trained Asajj Ventress with the hope of them defeating Palpatine and becoming the master himself, plus bounty hunter Durge and General Grievous, who would lead the separatists for him.
He was a powerful Sith in the force and capable of using deadly Sith lighning and highly skilled in blade combat and defeated the Jedi on many occasions, but when Anakin and Obi-Wan fought him for a 2nd time, he lost. Obi-Wan was wounded and asked Anakin to be lenient, but Anakin had already started to fall to the dark side himself and with 2 Light sabres in his hands, he beheaded Dooku.

Darth Maul
This was the Sith apprentice of Darth Sidious. He was secretly captured, trained and prepared to bring back the Sith. He served Paplatine without question and almost killed Qui Gon on their 1st meeting. Both escaped with their lives after a short battle, but it wouldn't be the last time the pair met, for when the Jedi and Padme went to Naboo, Maul was waiting for them, ready to defeat them with his double bladed Lightsabre. He took on both Jedi with ease, using a deadly combination of the force and sword combat and also strategically lured them into an energy shield corridor, which separated the trio and when Maul had his chance to strike, he fought the elder Jedi (Qui Gon) alone and with a fatal swipe, killed him.
In rage, Obi Wan charged forward and fought Darth Maul and at 1st was easily beaten, but using the force to draw his sabre, Obi leaped out the shaft he had fallen in and sliced Maul in half.
You would think that was Maul's end, but some say he still lived and soon found out he had a brother; Savage Opress. To Palaptine though, it mattered little, for he'd already moved on to his next apprentice; Count Dooku.

Palpatine/Darth Sidious
Palpatine was a scheming man. He started out as a chancellor, but he manipulated Anakin to turn him against the Jedi and Padme Amidala of Naboo to question the current chancellor's leadership. With no chancellor, Palpatine himself was voted and changed the laws to serve his cause which was always to bring back the Sith, of which he secretly was. Eventually his secret was found out, but it was too late, he'd already given the republic clone troopers a secret order (called order 66), to turn on their own side; the Jedi and also turned Anakin to the dark side. Many of the Jedi were killed, Anakin was now Darth Vader and the jedi council was unable to defeat him, thus the Empire was born., with the newly named, self-proclaimed Emporer Palpatine at its helm.
For years he ruled with a dark cloud, but he didn't bargain for a moisture farmer named Luke plying to Vader's good side and actually turning his own apprentice against him. With Vader joining Luke, he killed the Emporer, by throwing him down the shaft of the 2nd Death Star.
you would think that would be his end, but it wasn't, for he'd secretly created some clones and one of these clones returned to the dominant position. He even momentairily turned Luke to the dark side, but in the end, Luke and his allies prevailed and once again Palpatine was killed, never to return, or was he?
