What is the theme in The Politics of Aristotle by Aristotle?

Politics is something that all human beings in societies encounter. Aristotle seeks to understand it and to share this knowledge and these insights with readers. During the time that he wrote the book he was able to gain a rather direct view of more than one political structure that was functioning within his region of the world. This simply means that he has been able to write about it in ways that might not have been possible otherwise.
