Castellans of the Polish–Lithuanian Commonwealth

Castellans of the Polish–Lithuanian Commonwealth were the lower rank officials who could sit in the Senate of Poland. Their numbers varied with time and shifting borders of the Commonwealth.

In the Kingdom of Poland and later the Polish-Lithuanian Commonwealth, the Castellans (Polish: Kasztelan) were in most cases lower in precedence to the Voivodess (with the exceptions of the three Distinguished Castellans, and the important Castellan - that of Kraków - had a position in the hierarchy was actually superior to that of a Voivode).

Except for the Castellan of Kraków Land (which has its seat in a privileged city, as the Commonwealth's capital to 1596), Castellans were often considered subordinate to Voivodes. Two castellans from the Grand Duchy of Lithuania - those of Wilno and Troki - were also considered privileged, and had a status equal to those of the voivodes. Castellans were in charge of a part of a Voivodship called Castellany (Polish: Kasztelania) until the 15th century and from that time on their domain was divided into provinces for Greater Castellans and powiats for Minor Castellans.

From 1565, the principle of "incompatibilitas" ("incompatibility") forbade Voivodes and Castellans to hold a second title as a Minister, except for the post of Hetman.

The list below is based on the 1569 data. The number of castellans changed in the later centuries.
