was the Castellan (Kasztelan) of Cracow. Other Castellans, however, were considered to be lesser dignitaries than the Voivodes. The power of the Voivodes had declined since that title had been introduced about the 12th century; in the 17th century, however, they were still the highest regional dignitaries. They were the highest representatives of their Voivodeships to the Senat. They were the leaders of the Land Parliaments (Sejmiki Wojewódzkie, Voivodeship Sejmiks). They were in charge of assembling local nobility's military forces in the event of a pospolite ruszenie (levée en masse). Each chose a Deputy Voivode, who was responsible for setting local prices and measures. Voivodes were chosen by the King, except for those of Połock Voivode and Vilnius Voivode, who were elected by (and from) the local nobility (but still had to be appointed by the King). Except for the Castellan of Cracow Land (which has its seat in a privileged city, as the Commonwealth's capital until 1596), Castellans were often considered subordinate to Voivodes. A Castellan was in charge of part of a Voivodeship (till the 15th century called a Castellany, and thereafter divided into provinces for Major Castellans and powiats for Minor Castellans). After 1565, the principle of "incompatibilitas" ("incompatibility") forbade Voivodes and Castellans to hold a second title as a Minister, except for the post of Hetman. Ministers were comparable to modern central-government officials. They were 10 officials (5 for the Crown of Poland, 5 for Lithuania). The Ministers were the Grand Marshal of the Crown (Marszałek Wielki Koronny), Grand Marshal of Lithuania (Marszałek Wielki Litewski), Grand Chancellor of the Crown (Kanclerz Wielki Koronny), Grand Chancellor of Lithuania (Kanclerz Wielki Litewski), Vice-Chancellor of the Crown (Podkanclerzy Koronny), Vice-Chancellor of Lithuania (Podkanclerzy Litewski), Grand Treasurer of the Crown (Podskarbi Wielki Koronny), Grand Treasurer of Lithuania (Podskarbi Wielki Litewski), Court Marshal of the Crown (Marszałek Nadworny Koronny) and Court Marshal of Lithuania (Marszałek Nadworny Litewski). Court Marshals were considered subordinate to Grand Marshals. Lithuanian ministers, while vested with the same powers as Crown Ministers, were considered below them in precedence. Hetmans were also considered "Ministers" but had no seat in the Senat. A Marshal's duties consisted in providing security to the King and keeping order where he was present. Marshals commanded two regiments of infantry, a regiment of militia, and a special court of law with a marshal's judge (sędzia marszałkowski), marshal's clerk (pisarz marszałkowski) and assessors (singular: asesor).
