I want to know the answer to the following question:
WHat was a polish nobleman referred to as before the 15th century?
All the background I'm provided with is that "Representing the wealthier families of Poland and itinerant knights from abroad seeking their fortunes, this other class of rycerstwo, which became the szlachta/nobility ("szlachta" becomes the proper term for Polish nobility beginning about the 15th century), gradually formed apart from Mieszko". Is that enough to answer the question?
Answer: no
