Can we consider the military campaigns in the 13th century (i.e. Albigensian crusade, Baltic crusade, spanish reconquest) a crusade in the same way that earlier crusades (the first four crusades) were thought of as crusades?
What's the different in mindset here, and how did we get that change?
This is a troublesome question. On one hand, it's a very interesting one to answer. On the other, it looks very suspiciously like an essay prompt right as schools go into either exam week or midterms, and we most emphatically do not do people's homework for them.
So, with this quandary in mind, tell me this: what makes you think there was a change in the idea of crusading from the 12th to 13th centuries? What things did you notice that made you ask the question?
