There are limited resources in the world. Some countries have more ample access to desirable natural resources than others. When one country has something another country wants or needs, the country lacking resources may seek to gain access through warfare.

Religion has long been a trigger in wars. The Crusades were among the most prominent wars that took place over religious convictions. In that instance, it was an effort by Christian groups to seize control of Holy land from Muslims. Conflicts within a country often start based on different religious or philosophical differences among the people within a nation's borders. The goal of each side is often to gain control of the government to implement desired policies.
