The Byzantine army under Emperor Manuel I Komnenos suffered a crushing defeat in a narrow mountain pass at the hands of the Seljuk Sultanate of Rûm led by Kilij Arslan II. The ambush completely destroyed Manuel's heavy siege weaponry and broke his psychological ambition to reclaim central Anatolia for Christendom. This critical battle marked the permanent end of Byzantine offensive expansion in the East, sealing Christian Anatolia's transition into a predominantly Turkish and Islamic territory.

This catastrophic geopolitical defeat induced a pervasive millenarian anxiety and cultural melancholy within Byzantine court literature. Greek poets abandoned triumphant imperial panegyrics, turning instead to somber theological poems and apocalyptic literature that sought to explain the empire's military decline as divine punishment for moral corruption. This crisis fostered a highly interiorized, spiritualized style of poetry within Orthodox monastic communities on Mount Athos.
