This video explains the structure of medieval society, which was believed to be divided into three distinct orders: those who pray (clergy), those who fight (nobility), and those who work (commoners). This system, originating in the 10th century, defined specific functions for each estate, creating a hierarchical and coordinated organization. Membership in these estates was determined by birth and was for life, leading to minimal social mobility and significant inequality between privileged and non-privileged groups.
