I want to know the answer to the following question:
Which religious group made up the majority of the population in Prussia?
All the background I'm provided with is that "The Polish-speaking population concentrated in the south of the province (Masuria and Warmia) and all German geographic atlases at the start of 20th century showed the southern part of East Prussia as Polish with the number of Poles estimated at the time to be 300,000.". Is that enough to answer the question?
Answer: no
