Jan Długosz

Jan Długosz (1415–1480) was a Polish canon, diplomat and chronicler, regarded as Poland's first historian. Educated at the Kraków Academy from 1428, he served Bishop Zbigniew Oleśnicki as secretary and chancellor, and was ordained a priest in 1436.

He undertook missions for Casimir IV, including peace negotiations in the Thirteen Years' War and the education of the king's sons from 1467. He is best known for his Latin Annals of the Famous Kingdom of Poland in twelve books, covering 965–1480. Nominated Archbishop of Lwów, he died in 1480 just before the pope confirmed his elevation.
