Great War II. I was in Legion, but once it became apparent that we weren't going to enter I left. I was going to join a League alliance (obviously) but wasn't sure which. It ultimately came down to CDS vs. LUE and I chose the former on a whim. I'm sure my CN career would have been very different had I chosen the latter.
I don't remember lots about the actual war. We fought GOONS, so it started that tradition I guess.
