Sith civil war (Republic Dark Age)

The Third Sith Civil War occurred during the New Sith Wars, somewhere between 1,010 and 1,006 BBY. In it, the New Sith Empire collapsed into infighting. From among the rival warlords, Kaan emerged as the strongest Sith Lord, with two of the other powerful contenders&mdash;Kopecz and Qordis&mdash;allying with him. With their help, Kaan proclaimed himself Dark Lord of the Sith and established a Brotherhood of Darkness.
