A lord blinds his horse-master for presenting a colt the lord judges worthless, not seeing the hidden quality the breeder saw. The breeder's son takes the name Köroğlu ('son of the blind man'), raises that same colt into a peerless warhorse, and builds an outlaw stronghold from which he destroys the lord who maimed his father. The injustice born of the master's failure to perceive value becomes the engine of his own downfall.
The hero operates simultaneously as a raider who takes by force and a poet-singer who composes and performs verse. Authority over men is held not only through combat prowess but through the ability to put deeds, grief, and challenge into song, so that the sword and the saz are treated as paired instruments of the same reputation.
The narrative frames robbery and raiding directed at rulers and merchants as legitimate when the formal power structure has itself committed injustice. The outlaw stronghold stands as a counter-court where the wronged can get redress that the lawful order refuses to supply.
A thing that experts dismiss as defective can be the single asset that overturns their power, if someone reads its concealed potential and invests the patience to develop it. Köroğlu's horse, rejected as worthless, becomes the decisive weapon precisely because only the wronged party bothered to see what it could become.
