We know how the Sith ended in canon, but how did they begin?
Thousands of years before the Clone Wars, in canon, the Hundred Year Darkness was the period of time where the Sith Order was started by a rogue Jedi. They believed that in order to reach the true potential of the Force, one had to embrace the power of the dark side.
Predictably, the Jedi Council thought this was a ridiculous suggestion, and cast the rogue Jedi out. However, the rogue Jedi had many followers who collectively formed a new order…
At first there were many, enough to form the Sith Empire. They defeated the Old Republic, took over Coruscant and built a Sith Shrine. Eventually, they were plagued by in-fighting, which is no surprise because the dark side craves power. The Jedi were able to re-take Coruscant from the Sith, and built the Coruscant Jedi Temple over the Sith Shrine.
There weren’t many Sith left afterwards, and they were forced to abandon their homeworld, Moraband. They ended up destroying themselves, leaving only one survivor…
Darth Bane, creator of the Rule of Two.
Bane started a one thousand year campaign that eventually lead to the fall of the Galactic Republic and the rise of the Galactic Empire – as engineered by Darth Sidious aka Senator Sheev Palpatine.
In the end, as we all know, the Sith were ended when Darth Vader killed Sidious and a redeemed Anakin Skywalker died after turning back into the light.
