In the hierarchy of the new government system established, which class was the lowest class?
MrRa [10]

'Vassals were the lowest class in the newly established government system's hierarchy.

<h3>What is hierarchy?</h3>

A hierarchy is an arrangement of items (objects, names, values, categories, and so on). Hierarchy is a key concept in many disciplines, including architecture, philosophy, design, mathematics, computer science, organizational theory, systems theory, systematic biology, and social sciences.

A hierarchy can connect entities directly or indirectly, and it can connect entities vertically or diagonally. In a hierarchical system, the only direct links are to one's immediate superior or to one of one's subordinates, though a largely hierarchical system can also incorporate alternative hierarchies. Hierarchical links can extend "vertically" upwards or downwards by following a path with multiple links in the same direction.
