Łęczyca

Łęczyca was a Piast duchy centered on the fortified town of Łęczyca in central Poland. In 1337 Duke Władysław the Hunchback ruled the duchy as a vassal of the Polish crown.

Władysław died without an heir in 1352, and his duchy passed to the Kingdom of Poland. Casimir III reorganized the territory as the Łęczyca Voivodeship, making the former ducal lands part of the Polish Crown.
