Final answer:
Age grades in medieval Africa allowed children to forge social ties beyond the family and form lifelong bonds with others of similar ages.
Step-by-step explanation:
Age grades were a way for children in medieval Africa to forge social ties beyond the family. In some societies, age sets were organized into a hierarchical age grade system, dividing community members into different levels based on their age.
These age grades allowed children to interact with others of similar ages and form lifelong bonds that extended beyond lineage and clan boundaries in their community. They provided a platform for socialization and the development of solidarity among children and young adults.
