# Yanush Radzivill — The Deluge character guide > Yanush Radzivill in The Deluge by Henryk Sienkiewicz. **Role:** supporting **Also known as:** Radzivill, Prince Radzivill, Prince Yanush Radzivill, Yanush, Prince Yanush, the terrible Yanush Radzivill **First appearance:** 0007-i ## Snapshot The Grand Hetman of Lithuania whose cold ambition and Radzivill pride make him willing to trade his country's crown for a Swedish protectorate. ## Who they are As head of the Radzivill house and commander of Lithuania's armies, Yanush moves through the war like a man playing a longer, darker game than those around him. His dynastic scheming—marrying his daughter to Boguslav, hoarding power, reading foreign dispatches while his court dances—sets him against the very Commonwealth he has sworn to defend. His presence shadows the early arc: every rumor of his ambition forces loyal officers like Sapyeha and Kmita to ask where the true enemy stands. ## Relationships ### [Prince Boguslav Radzivill](https://www.betterreads.dev/discover/the_deluge_se/characters/prince_boguslav_radzivill) _family_ Prince Boguslav Radzivill and Yanush Radzivill are cousins and co-conspirators in treason against the Commonwealth. ### [Prince Boguslav Radzivill](https://www.betterreads.dev/discover/the_deluge_se/characters/prince_boguslav_radzivill) _family_ Prince Boguslav Radzivill and Yanush Radzivill are cousins and co-conspirators in treason against the Commonwealth. ### [Prince Boguslav Radzivill](https://www.betterreads.dev/discover/the_deluge_se/characters/prince_boguslav_radzivill) _family_ Prince Boguslav Radzivill and Yanush Radzivill are cousins and co-conspirators in treason against the Commonwealth. ## In the story ### [The Deluge](https://www.betterreads.dev/discover/the_deluge_se/chapters/the-deluge) The powerful prince who betrays the Commonwealth by allying with Sweden, representing the theme of honor and betrayal. ### [VII](https://www.betterreads.dev/discover/the_deluge_se/chapters/vii) The powerful Radzivill of Birji is mentioned as being occupied with public affairs and projects to elevate his house, contributing to the disorder in the Commonwealth. ### [X](https://www.betterreads.dev/discover/the_deluge_se/chapters/x) Mentioned as the prince voevoda who wrote the letter authorizing the commission for Kmita. ### [XII](https://www.betterreads.dev/discover/the_deluge_se/chapters/xii) Proposed as the commander to join; Zagloba praises him as an honest man and a soldier who will not surrender to the Swedes. ### [XIV](https://www.betterreads.dev/discover/the_deluge_se/chapters/xiv) Extracts a solemn oath from Kmita; speaks of approaching trials, treason, and enemies; hosts a grand ball at Kyedani, moving among guests with polished manners and hinting at his plans. ### [Chapter XV](https://www.betterreads.dev/discover/the_deluge_se/chapters/xv) The grand hetman and voevoda of Vilna, deeply troubled by the opposition to his treaty with the Swedes, grappling with fears of abandonment and infamy, and attempting to win Kmita to his side. ### [XVI](https://www.betterreads.dev/discover/the_deluge_se/chapters/xvi) The hetman who imprisoned them; his treason is the central conflict. ### [XVII](https://www.betterreads.dev/discover/the_deluge_se/chapters/xvii) The grand hetman, now revealed as a traitor to the Swedes; reluctantly yields to Kmita's demands but remains vengeful. ### [XVIII](https://www.betterreads.dev/discover/the_deluge_se/chapters/xviii) Hetman who betrayed the country to Swedes; prepares to suppress rebellion and orders prisoners moved to Birji. ### [XX](https://www.betterreads.dev/discover/the_deluge_se/chapters/xx) Hetman enraged by the battle of Klavany, pursues Volodyovski, and issues orders to Kmita. ### [XXII](https://www.betterreads.dev/discover/the_deluge_se/chapters/xxii) Returns to Kyedani, confronts Kmita about the failed mission and the letter, suffers an asthma attack, and later attempts to justify his actions to Kmita. ### [XXIII](https://www.betterreads.dev/discover/the_deluge_se/chapters/xxiii) Hosts the banquet, announces Swedish victories, and tries to sway the nobility to his cause. ### [XXIV](https://www.betterreads.dev/discover/the_deluge_se/chapters/xxiv) Reveals his conditional alliance with Sweden and his ambition for the crown; sends Kmita to Prince Boguslav and Karl Gustav. ### [XXV](https://www.betterreads.dev/discover/the_deluge_se/chapters/xxv) Gives Kmita letters and a pass, bids him farewell with fatherly advice. ### [XXVI](https://www.betterreads.dev/discover/the_deluge_se/chapters/xxvi) Referenced as the prince voevoda of Vilna; his letter to Boguslav reveals his plans to massacre confederates.
