This study analyses Plato’s work Crito with the rhetoric analysis method. Plato’s work Crito is one of his most important works of political philosophy. In this work, Plato develops the key qualities of his own political philosophy.  Inspired by the fact that Socrates does not escape the capital punishment, he is sentenced in order not to undermine the ethical principles to which he always adheres, Plato handles duty, citizenship and justice concepts. Thus, he develops his philosophical understanding of what qualifications a “polis” or a citizen should have. Considering Plato’s influence and decisiveness on all history of philosophy, Crito needs to be re-analyzed with new analysis methods. In this context, considering that Plato created his works in order to establish a state that he idealized, Crito needs to be analyzed with rhetoric analysis method which handles the analyzed subject based on the purpose of the author.
