I want to know the answer to the following question:
What group did the crusaders who attacked Valencia belong to?
All the background I'm provided with is that "In 1238, King James I of Aragon, with an army composed of Aragonese, Catalans, Navarrese and crusaders from the Order of Calatrava, laid siege to Valencia and on 28 September obtained a surrender.". Is that enough to answer the question?
Answer: yes
