Probably not Tony.
What I'm saying is that the Republic and Jedi thought that Revan and Malak were the only Sith. Traya, Sion and Nihilus proved them wrong as did the Sith Empire when it retook Korriban.
Did some research last night. Found out 2 things.
1) There is a difference between the Stark HS Conflict
and the HSWar
2) The Stark Conflict took place 44 BBY, while the Hyperspace War took place in 5000 BBY, between the Republic and the Sith Empire. This was back in the time of Naga Sadow, roughly 1500yrs before Revan. The defeat of Sadow resulted in his self-imposed exile to Yavin 4.
The Republic versus the Stark Commercial Combine. The war lasted only a year (44 BBY), and you'll be shocked to learn that it was orchestrated by Darth Sidious as part of his plan to take over the Galaxy. Notable events from the war include Nute Gunray becoming Vicroy of the Trade Federation, and Finis Valorum becoming chancellor.

Don't know where/if the mix up came from (might just be me), but from reading Cloak of deception, I can't remember whether that was when he was made viceroy, or simply the Neimoidians were left in control of the Federation. I'm inclined to the latter, but the memory is foggy today.
