De Cive

De Cive ('On the citizen') is a book by Thomas Hobbes "published" in 1642 (and more properly in 1647), and one of his major works.

It anticipates the classical republican line of argument in the better-known Leviathan. The famous phrase Bellum omnium contra omnes (war of all against all) appeared first in De Cive.
