The Latin Rule was specific codes for the Templar Order. Its 72 clauses defined the ideal behaviour for the Knights, such as the types of garments they were to wear and how to eat. As the Order grew, more guidelines were added, and the original list of 72 clauses was expanded to several hundred in its final form. Some of my family were these knights.
