rican political institutions, it's necessary to understand the rationale for British colonial institutions that survived the empire. Political institutions in England's American colonies were neither direct imports from England, nor home-grown creations of autonomous colonists. Instead, they emerged from efforts of the English Crown to assert control over their colonies amid limited English state and military capacity. Agents of Empire explores the strategic dilemmas facing a constrained crown in its attempts to assert control. The study argues that colonial institutions emerged from the crown's management of authority delegated to agents-first companies and proprietors establishing colonies; then imperial officials governing the polities they created. The institutions remaining from these strategic dynamics form the building blocks of federalism, legislative power, separation of powers, judicial review, and other institutions that comprise the American polity today.
