The Order of the Sith is an evil order of monks who have tapped into the Force. Sith, as their members are called, are generally seen as the antithesis to the Order of Jedi Knights, and although the tenets of these two organizations are not necessarily set specifically at odds with one another, the Sith are more widely regarded as villains than anything else.

The Sith are a much less organized group, and are much more mobile, not having a true base of operations, and instead preferring to operate on their own terms and in their own way. Most Sith have one, rarely two, apprentices whose training is their responsibility, and all the traditions of their order are passed along by oral teachings, making internal consistency a bit more difficult for the Sith order than it is for the Jedi.
