The Sith is an organization in the fictional Star Wars universe. It is an ancient interstellar kratocratic government led by those who seize power through force or cunning. Sith characters are frequently depicted as amoral, cruel, selfish, sadistic and violent. The Sith Order established several Sith Empires and have undergone numerous incarnations throughout their existence. The Banite Sith Order, as depicted in the Original trilogy and Prequel trilogy, was founded by Darth Bane; this sith dynasty lasted between circa "1,000 BBY-4 ABY"; (Before Battle of Yavin/After Battle of Yavin; "0 ABY" being the destruction of the first Death Star) ending with the death of Palpatine and Darth Vader. During this "Banite dynasty" there existed only two sith members at a time: a master and an apprentice.
