"Wielka Improwizacja" is a key monologue in the third part of Adam Mickiewicz's "Dziady" where the protagonist Konrad addresses God, asking for power over human souls and elevating himself above others. Konrad's speech highlights the power and importance of the poet as he compares himself to God and accuses Him of neglecting humans. Mickiewicz uses language and poetry to convey the idea that the voice can deceive and that true power lies in creating great works of art. The monologue takes place after Konrad is left alone following a Christmas gathering with other prisoners, showing its confessional nature and reflecting on the time it was written - after the failed November Uprising in 1832.
