I don't have enough context to write an accurate overview. "1290" could refer to a year with various historical events, but without knowing which specific event, person, or topic you're interested in, I cannot provide an accurate 2-sentence summary without potentially inventing facts. Could you clarify what aspect of 1290 you'd like me to explain?
