What does “banalités” refer to in manorial lordship?

The story behind the answer

In many French seigneuries, banalités were compulsory charges tied to the lord’s monopoly over essential facilities. Peasants were obliged to grind grain at the seigneur’s mill, bake in the communal oven, or press grapes and olives in the lord’s press, paying a set fee each time. Private handmills or home ovens were often banned, enforcing use of these installations and guaranteeing the lord a steady income.

The term comes from the “ban,” the lord’s authority to command, not from “banal” meaning ordinary. Because bread and wine were dietary staples, these monopolies touched everyday life and became emblematic of seigneurial burdens. They were hotly resented and featured among the feudal dues targeted by the French Revolution; the August Decrees of 1789 moved to abolish them, though compensation to lords complicated enforcement.
