I thought of this question while reading through the "What if Rome had remained a Republic?" thread, and I think it could use its own thread.

What would have happened, in your opinion, if the Gracchi (sp? can't sp for sh) bros. had succeeded, whether by force of arms, influence, damn good luck, etc...

Would Rome have lasted longer? Would it have stagnated in Italia and never grown? Would it have never conquered what it did? Would it have burnt out too fast? I have no idea, so please- enlighten me.
