Krzysztof Warszewicki

Krzysztof Warszewicki (1543–1603), also known as Christopher or Christophorus Varsevicius, was a Polish noble, courtier, diplomat, politician, orator and writer. He was described in a 1960 article in journal The Polish Review as a "very prominent politician and prolific political-juridical writer", a "typical Renaissance statesman" and a "zealous Catholic".

He studied at University of Wittenberg. That last decision ended up badly for him; when the Hapsburgs lost the elections, he suffered from royal disfavor and exile which may or may not have been voluntary (sources vary). He supported strengthening the royal power of that of the nobility. He also supported the idea of a Crusade against the Ottoman Empire. Another royal funeral at which he spoke was that of Catherine of Austria, Queen of Poland (d. 1572).
