Thomas Hobbe's Social Contract Anthology: Exploring Ethics: An Introductory Anthology, 5th Edition
This is a shortened version of his theory: Thomas Hobbes's social contract theory proposes that individuals in a society agree to give up certain freedoms in exchange for protection and stability provided by a governing authority (a sovereign) with absolute power. This agreement, whether implicit or explicit, forms the basis of the state's legitimacy and authority over its citizens.
Again, I am just looking for a specific country that is a good example of his theory.
