The institution of monarchy developed during the Middle Ages against the backdrop of the previously endemic struggles between feudal power agencies. The monarchy presented itself as a referee, aa power capable of putting an end to war, violence, and pillage and saying no to these struggles and private feuds. It made itself acceptable by allocating itself a juridical and negative function, albeit one whose limits it naturally began at once to overstep.
