I want to know the answer to the following question:
Where did the Carnival gestate out of the purview of rules?
All the background I'm provided with is that "The result was the uninterrupted celebration of Carnival festivals in Barranquilla (see Barranquilla's Carnival) now recognized as one of the Masterpieces of the Oral and Intangible Heritage of Humanity.". Is that enough to answer the question?
