There are many forms of government and "tribalism" is one which doesn't uphold a central authority. This is <em>a primitive form of government</em> which is no longer common these days.
In tribalism, people associate themselves into groups according to territories. So,<u> they feel entitled to possess the resources within their territorial boundaries. </u>They also make their own sets of rules to follow. Every tribe has <em>its own unique kind of lifestyle</em>. However, this form of government is <em>not well-protected and may often face misunderstandings and sometimes wars. </em>
