Many kings would plan and carry out invasions to gain goods, land and other loot and to expand their rule because many of them worried that another power would get too strong and take over their kingdom, and every king wanted to avoid that because they had become very fond of being king.
The difference of opinion and in particular with opposing opinions is a source of much conflict between and among so many religious groups. This derives from the sense of "entitlement" which comes from, in particular, monotheistic beliefs. As one group gathers in belief in one way and one god and that one god's system of rules, it naturally follows that that group will determine by logic, that all opposing beliefs are wrong, and that therefore the other religious groups are wrong in their beliefs. From this can arise conflict when one tries to overpower the other to have a bigger voice or control.
