I want to know the answer to the following question:
During what time period did the Albigensian Crusade occur?
All the background I'm provided with is that "At that time the south of France was the stronghold of the Cathar or Albigensian heresy, named after the Duke of Albi, a Cathar sympathiser and opponent to the subsequent Albigensian Crusade (1209–1229).". Is that enough to answer the question?
Answer: yes
