South Prussia
In the Second Partition of the Polish-Lithuanian Commonwealth (1793), Prussia had acquired South Prussia, and had established a branch of its Cadet Corps schools in Kalisch. In 1804, in Warsaw, a humanistic secondary school for boys was opened, divided according to the Prussian educational model into six classes, plus two preparatory ones. In German, it taught Latin, Greek, German and French, philosophy, ethics, mathematics and natural sciences, and (in Polish) the Polish language.
