Banjeprus is arguably the Grenwal Confederate Empire's biggest military powerhouse, being possibly equal to, or even outshining the Archduchy of Oesterholm, who are sometimes considered its biggest rival. Some skirmishes with its neighbor states in the empire made Branjeprus bigger than ever before, and the state may quite possibly grow even further.
Nonetheless, the current king of Branjeprus, King Ferdinand III. of Branjeprus also made Branjeprus a center of Art and Learning, in stark contrast to his father who tended to de-fund the arts and sciences in favor of the military; in peacetime, no less. Today, the universities in Morber, Branjeprus' capital, are almost overflowing with eager students.
King Ferdinand III. also happens to be the current Emperor of Grenwal, meaning Morber is also the current capital of the entire Grenwal Confederate Empire.
