Q: At this time, none of the tribal confederations of Mongolia were united politically, and arranged marriages were often used to solidify temporary alliances. Temüjin grew up observing the tough political climate of Mongolia, which included tribal warfare, thievery, raids, corruption, and continual acts of revenge carried out between the various confederations, all compounded by interference from foreign forces such as the Chinese dynasties to the south. Temüjin's mother Hoelun taught him many lessons about the unstable political climate of Mongolia, especially the need for alliances.
