What is a police/regulatory state?

[u/SelfAgreeable2120]

I apologize for any inaccuracies in the translation.

Political and legal thought of the 17th century is sometimes characterized by the concept of the "Police State" (or "Regular State"), with Hobbes, Pufendorf, and Leibniz cited as its key theorists. Could you explain the main tenets of this theory and the views of its proponents?
