According to the laws of Genghis Khan, what was forbidden regarding peace treaties?

The correct answer points out that it was forbidden to negotiate with disobedient monarchs or peoples according to the laws of Genghis Khan. This reflects his broader strategy of consolidating power and maintaining authority within the Mongol Empire. By prohibiting negotiations with those who defied or resisted his rule, Genghis Khan aimed to eliminate any form of dissent and ensure that loyalty was rewarded with peace and stability. It underscores his focus on unity and the importance of following the Mongol command structure, which was crucial for the expansion and cohesion of his empire.

The other options do not align with the historical context of Genghis Khan's laws. Making peace only under certain conditions could imply a degree of flexibility that was not characteristic of his approach to governance. Similarly, the idea of making peace treaties with any powerful ruler would undermine the strict hierarchy and authority he established. Lastly, limiting negotiations solely to neighboring tribes does not reflect Genghis Khan's willingness to engage in broader strategic alliances as long as they aligned with his interests and authority.
