Czerwińsk Privilege
In 1422, in Czerwińsk nad Wisłą (Czerwińsk upon Vistula), King Władysław Jagiełło issued the Czerwińsk Privilege - one of the most important noble privileges. The document introduced the principle of neminem captivabimus (prohibition of imprisoning nobles without a court verdict) and banned property confiscation without a court ruling, which significantly strengthened the nobility's position in the state.
