So WI Sertorius who ruled Hispania managed to capture Pompey after defeating his forces at Sucro. Doyou think he could create a viable state that cul resist ome. Also how would the balance of power change in Rome with Pompey dead?
Without Pompey, maybe we could have a slower and harder war against Pontus, giving opportunity to other generals to arise, maybe more than just one. Eventually, it may allow populares or centrists to raise more easily and with less violent late Republican era?
If Sertorius captures Pompey and presumably wipes the floor with his army (or gets it to defect), then he's marching on Rome and/or demanding they make a lot of concessions to him-and with the threat of him marching on Rome being very real...I think they'll go with the concessions, given how this is the same senate that backed down when Pompey threatened to march on Rome, and Pompey's threat wasn't as dire.
Sertorius had Spain but he had no support outside of it, by this point the Empire is to big fall to him without that support.
As for viable long term state, no I don't think so, this was just a little to early for that to happen in any real way. Romans were horrifically patriotic and Sertorius main aim in life was to return back to Rome, and be a Roman.
