Snoke

Snoke was the "apprentice" of Darth Stultuminis who eventually became the ruler of The Sith Republic when his master died.

Training
Snoke was a Sith Warrior that worked for Binks in the era of the Sith Republic. Many people considered him to be Binks' apprentice, but this was not the case. Binks trained many sith, but Snoke was the person he took the most interest in due to his high Midi-chlorian count. After Binks' death, Snoke trained the Sith Master's second most powerful apprentice, Darth Iroquois. Like Binks did for him, Snoke groomed Iroquois to take his place as Grand Master when he died. However, like the hundreds of generations of Sith lords before him, Snoke was cautious that Iroquois would try to kill him and any time he engaged with combat with him without permission, he would punish him to create a habit of staying away from him. Unfortunately, this plan did not work and one day, Iroquois engaged in combat with Snoke, scarring him and giving him the appearance he has in The Last Jedi. Snoke could barely maintain keeping himself alive. He wanted to leave the Republic in order to keep himself alive, but he could not let Iroquois rule. So, he needed to kill him before he could do anything else.

Slaughter of the Many
Snoke was preparing to kill Iroquois in secret but many of his soliders attempted to stop him. He had to kill them to prevent the story from spreading and to prevent any suspicion. Which is exactly what he did. As Iroquois was sitting on Snoke's throne, Snoke but the lightsaber emitter towards the throne, and ignited it. Iroquois was dead. Now, all Snoke had to do was find someone else to rule. Eventually, he chose Darth Lotia. What he did after this was unknown.
