The '''Wars of Secession''' were tumultuous rebellions that tore apart the [[Necrontyr]] empire throughout its history.^{{Fn|1}}

The '''First War of Secession''' took place before the Necrontyr race battled the [[Old Ones]] in the [[War in Heaven (Necron)|War in Heaven]] or encountered the [[C'tan]]. A result of the vast expansion of their race, the nobles of the [[Necron Dynasty|dynasties]] established independent realms from the Necrontyr empire and fought against both the [[Triarch]] and one another. It was only ended when the Triarch found a greater enemy for the dynasties to unite against, the Old Ones.^{{Fn|1}}

The '''Second War of Secession''' took place during the [[War in Heaven (Necron)|War in Heaven]]. As the war against the Old Ones deteriorated and the Necrontyr race became but a minor annoyance to them, the Necrontyr dynasties again fractured and fought for dominance over one another. The wars only ended with the apperance of the [[C'tan]], whose promises of immortality and victory over the Old Ones gave the Necrontyr reason to unite once more.{{Cite This}}
