In chapters 12-13 of the Second Treatise of the Two Treatises of Government (1689), Locke distinguishes legislative, executive, and federative power, arguing legislative and executive should not rest in the same hands, with the executive subordinate to and removable by the legislative. This is a functional distinction, not a demand for three fully separate institutions — Locke does not include the judiciary as a distinct branch. Still, executive subordination to the legislature is the practical seed of limited parliamentarism.
