Four cornered cap from Poland
A Rogatywka is the generic Polish name for a four-pointed, asymmetrical cap worn by various Polish military formations over time. It is a distant relative of the konfederatka, which was used by Bar Confederation members in the 18th century. However, similar caps have been worn by light cavalry since the 14th century.
The four-pointed top and short peak of a Rogatywka are typically made of black or brown leather. Although the English word “rogatywka,” which is derived from “róg,” which means “horn” or “corner,” appears to mean the same thing as Czapka, the Polish word “czapka” refers to both Rogatywka and all caps (not hats).
