It strongly depends on where are you setting your Saga and how spicy is the mix between historic events and Hermetic history timeline, if applicable.
For example our saga is placed in the Isle of Man, and 1220 is a pretty fitting year to play there. From the historical We have a pretty interesting mix of gaelic peasants and norse rulers, a lot of civil wars, revolts, and political maneuvering; from 1225 to 1226 there will be a civil war of, the king will have his brother Godred Dunn killed in 1236 and dies in 1237, and in 1248 one of Dunn's sons will kill the new crowned King Reginald II while his brother claims the throne, which will start a cil war that will last until 1252 (a lot of years of war in an island so small that you can cross it in one day from side to side!), all mixed with the increasing influence of the Dominion, which 1260 being a very interesting year because there is a prophecy saying that Armaggedon will arrive 1260 years afer the birth of Christ... and in the Mythic landscape the norse dudes are expected to have their wizards (hello, Order of Odin!) and the island has a long history of hermetic tragedies; in 866 the Covenant of Rector Maris was founded in the island and destroyed within 6 months, in 938 another attemt was made to establish a covenant there, Rector Novus, and was destroyed within a year, but only 6 years later Diedne founded the Caarjyn Arawn covenant, which managed to survive and prosper (well, until the Schism War, when it was destroyed anyway), and there was a last attemt to settle magi there in 1160, founding the Servus Maris covenant, which was destroyed again in 6 months (that makes a lot of hermetic ruins to explore), and a letter was sent to Loch Leglean's tribunal, saying something like "don't ever try to come back", which was confusing, because Man have three big dragons, one of them deeply hating magi and suspect of being friend of the diedne magi back in the day, but it doesn't seem like the kind of enemy who writes threatening letters... and on the top of that the island is claimed by both the Loch Leglean and Hibernian tribunals, but the issue was relatively calm as after all there weren't any magi there, but if our characters manage to settle there and survive whatever destroyed the former establised covenants there, a storm of inter-Tribunal proportions will start around the island, asking it to decide for a tribunal, being claimed by both, and so on. And then there are the fae, of course, with Man himself, being a faerie king that pretty much actually owns the island.
So I think the trick is picking a place, and then reading the hermetic timeline for events happening there and doing a quick search on wikipedia for historical events, and then place your saga in the right time and place that ensures a lot of ideas for stories. A lot of interesting stuff happened in a lot of places at different times; if you dig long enough the real problem will be with possible settings and times to discard.
