Necessities of State: Police, Sovereignty, and the Constitution

Abstract

Over the last fifteen years, legal historians have been exploring conceptualizations of the state and state capacity as phenomena of police. In this essay, I offer a genealogy of police in nineteenth-century American constitutional law. I examine relationships among several distinct strands of development: domestic regulatory law, notably the commerce power; the law of indigenous peoples and immigrants; and the law of territorial acquisition. I show that in state and federal juridical discourse, police expresses unrestricted and undefined powers of governance rooted in a discourse of sovereign inheritance and state necessity, culminating in the increasingly pointed claim that as a nation-state the United States possesses limitless capacity “to do all acts and things which independent states may of right do.”
