I want to know the answer to the following question:
In 1203, what area was a stronghold of the Cathar?
All the background I'm provided with is that "In 1203, Dominic joined Prior Diego de Acebo on an embassy to Denmark for the monarchy of Spain, to arrange the marriage between the son of King Alfonso VIII of Castile and a niece of King Valdemar II of Denmark.". Is that enough to answer the question?
Answer: no
