Recent Star Wars tie-ins have added another dimension to the Sith's plans, suggesting they used the dark side to prey upon Jedi from afar. The Jedi believed the Sith extinct a thousand years before the events of Star Wars: Episode I — The Phantom Menace, but in reality their ancient enemies had retreated into the shadows to operate in secret. Darth Bane reinvented the Sith around the Rule of Two, establishing that there should only ever be two Sith at any one time, and he charged them with playing the long game — undermining the Jedi and the Republic in secret rather than overtly.
The Sith's actions during the millennia after Darth Bane remain a mystery. They certainly don't seem to have been especially successful at first, because by the High Republic Era — some 800 years after Darth Bane's defeat at the hands of the Jedi — the Republic was expanding across the galaxy, the light of the Jedi shining more brightly than ever before. Something clearly changed in the next two centuries, however, as the Republic became introverted and the Jedi retreated from the wider galaxy for fear of the dark. It's reasonable to assume the Sith played a key role in this, their unseen hand manipulating events; the Sith ultimately went into politics to beat the Jedi, recognizing the Jedi had completely abandoned the political arena, and they could operate there without any major risk.
