During the Clone Wars, the Maldrood sector joined the Separatists.
Following the Battle of Endor, the Maldrood sector was among the first sectors to throw off the Empire. However, the sector soon became the core of the Greater Maldrood, an Imperial faction established by High Admiral Treuten Teradoc.
When Grand Admiral Zsinj was killed, Teradoc declared himself "High Admiral of the Mid Rim" and found himself in the middle of a war between Admirals Teren Rogriss of the Empire and Ackbar of the New Republic. Teradoc was eventually defeated by the New Republic forces and he was forced to abandon the Greater Maldrood and flee to the Deep Core.
In 26 ABY, the entire sector was conquered by the Yuuzhan Vong after four battles.
