Medieval Lithuanian History – HIST1602 – Lecture Notes - Professor: Jonas Matas –1215 AD -1224 AD –– Class 11 – Rebellion and Reconsolidation
- The newly acquired lands of Yatvyagi are led by a Russian Orthodox Count Vytautas Astikaitis.
- Dausprungas demands his conversion to consolidate and legitimize his rule.

- Dausprungas’s demand is immediately refused.
- Dausprungas calls of Vytautas’s arrest.
- Vytautas raises his men and declares open rebellion.
- Seeking to reestablish herself as the leader of Zemaitija, Matild mobilizes her own faction and pledges her support.
- Vytautas is also supported by his alliances by other local Russian lords.
- Dausprungas once again calls on his network of Polish dukes to help defend his title.

- However, before the Polish forces can arrive to Dausprungas’s aid he is captured by the rebellion. He is brutally executed by Count Vytautas.
- Once the Polish forces arrive, Vytautas and Matild are both captured and executed.
- Despite the defeat of rebellion’s ringleaders, the realm is severely weakened by Dausprunga’s death.
- His lands are split between his two sons, as the Dukes of Lietuva (Lutuveras) and Zemaitija (Rimgaila).


- Within a year of Lutuveras’s reign he dies from the aggravation of his wounds sustained in battle during Vytautas’s rebellion, and is succeeded by his young son Dausprungas III.

- His mother Adleta of Chelmo, the daughter of the influential Duke of Kujawy, serves as the realm’s regent.
- She is noted for her ambition and much of Dausprungas’s III success as a leader is attributed to her.
- Using her father’s station in the Polish court, Adleta is able to secure Dausprungas III a betrothal to Wolislawa Ossowski, the daughter of the Duke of Mazovia.

- The security from the Mazovian alliance is short-lived as in 1218 AD Wolislawa dies after a period of illness.
- Additionally, Dausprungas’s uncle Duke Rimgaila of Zemaitija, a strong claimant to Dausprungas’s title, also has an alliance with Mazovia.

- Desperate for a viable alliance, Dausprungas betroths Rycheza Bodzeta, the daughter of the powerful Duke Strasz of Gorny Slask.

- Meanwhile, the crusader realm of Zaporoze has passed to the one year old Queen Anele Suvalkija, whose sole heir is the Duke of Mazovia.
- The Kingdom is also subject to various invasions by Turkic tribes in the east.
- This marks a significant change from the Zaporoze’s quick rise to power in the region.

- In 1222 AD, Dausprungas officially presses his claim on Zemaitija, encouraged his mother Adleta.
- Adleta convinces her father to support Dausprungas’s claim.
- The Duke of Mazovia, seeking to limit direct confrontation with its neighbor Kujawy, does not come to Zemaitija’s aid.

- Rimgaila is outnumbered and suffers an early significant defeat in Siauliai.

- Soon after Dausprungas’s forces siege Raiseiniai, capturing Rimgaila and forcing him to surrender.

- A reunited Lietuva stands strong in the Baltic.

- In 1224 Dausprungas officially takes control of the duchy’s affairs, though his mother Adleta remains a trusted advisor during his rule.
