How could you explain the overconcentration on the 4RS in the curriculum of the castle schools?

The overconcentration on the 4Rs—reading, writing, arithmetic, and religious instruction—in the curriculum of castle schools can be attributed to the need for foundational literacy and numeracy skills essential for administrative and clerical roles within the feudal system. These subjects were deemed critical for the training of future leaders and clerics who would manage estates and the church. Additionally, emphasizing religious instruction reinforced the moral and ethical framework of the time, aligning education with the values of the ruling class. Consequently, this focus reflects the socio-political priorities of the era, shaping a curriculum that served both practical and ideological purposes.
