I can't think of any single event, not off the top of my head at least. Most of known history can teach some sort of lesson applicable to some problem we're currently facing, whether personal or political or whatever. On the other hand, we've only got so much time available to us, and you could spend multiple lifetimes on very specific historical events.
I think all you can really expect of people is to pay attention to what they're taught and keep an open mind about things, try to relate what has happened with what is happening. A bit of ignorance about the past is just inevitable.
