[Star Wars]If Sidious follows the rule of two, why does he have so many other Sith underlings?

In the movie and TV shows cannon we have seen Dooku, Maul, Asajj Ventress and the Inquisitor (also is there a Sith inquisition?) and maybe others. Are these not considered "true Sith?"

No, they're not technically Sith. But the rule of two is basically made to be broken. A Master will often cultivate several potential apprentices so that if the official one dies, they can be replaced. And the apprentice will often take on secret apprentices so that they have someone ready to go when they overthrow the master.

However Sidious did *not* believe in the Rule of Two. His own philosophy was a Rule of One: That he was the culmination of the Sith order. To him, his apprentices were merely tools, and he intended to rule eternally over the galaxy.
