Civil war (War of the Daleks)

In the aftermath of the first civil war between the Daleks loyal to the Dalek Prime and the Daleks who followed Davros, thirty years following the apparent destruction of Skaro, a brief civil war erupted on Skaro as the Dalek Prime sought to wipe out Davros' remaining followers.

Behind the scenes

 * AHistory speculatively dates the trial and renewed civil war to c. 4693, and puts that it was followed by Emperor Davros's invasion of Earth about a decade later.
