Policraticus or Polycraticus is a work by John of Salisbury, written around 1159. Sometimes called the first complete medieval work of political theory,[1] it belongs, at least in part, to the genre of advice literature addressed to rulers known as "mirrors for princes", but also breaks from that genre by offering advice to courtiers and bureaucrats.[2] Though it takes up a wide variety of ethical questions, it is most famous for attempting to define the responsibilities of kings and their relationship to their subjects.
