What happened to dante that led him to write epic poetry?

I think this is the answer not sure.

He was exiled from Florence for political reasons. Very roughly speaking, Dante was an advocate of a strong Holy Roman Emperor, and thought Florence should subject itself to the HRE. This made him two sets of enemies: those who thought Florence should rule itself, and those who wanted to ally it with the secular claims of the Papacy.

the first forms of writing came from them in the form of pictographs around 3100 bc.
