Darth Sidious, the Dark Lord who viewed himself as the pinnacle of the Sith.
The Rule of One was a self-affirming doctrine conceived by Darth Sidious to replace the Rule of Two, a long-standing Sith doctrine he considered to be outmoded, it having fulfilled its purpose by placing him in power.[1]
The Rule of One was first articulated in Darth Sidious's political treatise Absolute Power, wherein he stated that the Sith would be embodied by a sole reigning Dark Lord—Sidious himself—who would live forever as Emperor of the galaxy, having no need to train a replacement, and availing himself solely of capable executors of his will, talented in the Force as dark side agents. These agents learned a smattering of Sidious's abilities, but did not assume even a fraction of his authority.[1]
Darth Tenebrous, a Dark Lord of Bane's Order prior to Darth Sidious, calculated that the rise of "One Sith," a Dark Lord so powerful he would have no need of replacement, was inevitable.[2]
