Defeat of Casimir III
On 1349, Dmirto Dedko of Halych would defeat and kill Casimir III in battle with the help of his former brother in law, Liubartas which would cause Poland to have succession issues due to Casimir III having no sons and the King of Hungary wanting the succession of Poland, the succession issue of Poland was between Bolko of Swidnica, Louis II of Brandenburg, Louis of Hungary, and Bogislaw V of Pomerania would vie for the succession of Poland themselves.
Bolko of Swidnica would take control of his uncle, Casimir III’s Kingdom defeating his other rivals in the crown due to the support of the other Piast Dukes in Silesia and Mazovia in 1352 with him being crowned with his son, Boleslaw as the heir.
Meanwhile in Red Ruthenia, Dmitro Dedko and Liubartas would be happy on the defeat of their rivals, however, Dmitro himself would betray Liubartas and kill him taking Volhynia for himself and reunited Galicia and Volhynia in 1352 and continued giving tributes with the Mongols and crowning himself as King of Ruthenia as Demetrius I of Ruthenia and securing his own succession for his children to inherit Ruthenia despite of his own questionable legitimacy.
