Why was a more detailed Franciscan rule needed as the order grew?

As the Franciscan order grew rapidly—eventually numbering 5,000 members within a decade—it faced significant challenges that the original, simple rule could not address. During the early years, the friars relied primarily on the personal example of St. Francis of Assisi to guide their lives, but this informal approach proved insufficient for an organization experiencing such swift expansion.12

The need for a more detailed rule arose from several factors:

• Lack of Structure: The order lacked the necessary institutional framework to manage its increasing numbers and practical affairs.1
• Internal Conflict: As the membership expanded, disagreements emerged regarding the observance of the vow of poverty. The rapid growth created a practical need for settled monastic houses, which conflicted with the strict, literal interpretation of poverty found in the primitive rule.2
• Organizational Guidance: To correct the lack of administrative guidance, Francis sought to establish clearer regulations for discipline, preaching, and entry into the order, eventually leading to the papal approval of the Regula bullata in 1223.1
