Location
Cause → Event → Consequence
Despite earlier cooperation in 1199, Duke Roman the Great of Galicia-Volhynia invaded Lesser Poland in 1205, threatening the territories of Leszek the White and his brother Konrad I of Masovia. Long-standing border disputes between Polish and Ruthenian principalities provided the broader context for this confrontation.
Roman's army was surprised and decisively defeated by Polish forces near Zawichost on the Vistula River. During or following the battle, Roman the Great was killed, ending his campaign into Lesser Poland and eliminating the principal military threat to the Polish dukes.
The victory greatly enhanced Leszek the White's prestige, allowing him to consolidate power in Kraków. His brother Konrad, now of age, demanded a share of power, leading to a division of territory between them. Roman's death also triggered a prolonged war of succession in the Principality of Galicia-Volhynia.
