I don't think it was a 'rebellion' as much as a 'Civil War' between Gems. I think the conflict escalated and both side's withdrew after serious loss on both sides(hence why an out of the way planet like Earth has so many Gem Monsters despite having no one check on them for countless years), during this the Crystal Gems may have had to deal with a damaged warp stranding them. And as to what I think said conflict was about? Coexistence with other sapient species against disregarding them entirely and if they are bothersome and impede Gem progress (confronting them or just in the way) then to do away with them. This makes sense because the Gems have been shown not to think much of humanity but respect life enough not to let them get hurt, especially because of Gem monsters, which are 'Their Problem' to begin with.This brings up several thoughts on earlier parts of the series, such as Steven discovering healing powers, that Lapis saw before returning home.(Not sure which side she was on, could have fallen into the same side as the gems and ended up with regrets for all we know), but Stevens healing powers could be viewed as a great asset in recovering Gems who sustained greater injury's and possibly restart said war. Judging by Peridot's reaction she was 'very' cautious upon discovering the sticker so the Gems on the home-world may only now be starting to make a move and not be sure who is even there. Also  mentioning the Gem beasts they have bubbled and Steven trying to 'heal' them, this may end up rallying reinforcements if things go south or if it happens soon(the Gems might try and get him to do this with recent events) and said bad Gems find out he can not only heal but restore cracked Gems, then he will likely become a top priority soon enough. Also just remembered Pearl in 'Space Race', maybe their society become a space faring one and it went south from there.

And adding we don't really know anything this is all just us thinking up stuff, and I hope many of you find my idea's informative and look forward to responses.
