One system, many levers
In the Islamic Republic, formal power is split across civilian, military and religious-supervisory institutions. Faces rotate; the command architecture —who can veto, who controls arms, who interprets the constitution— is stickier. This piece walks that architecture without personal names: only roles and links, like an intelligence org chart.
The constitutional apex
The Supreme Leader holds strategic oversight of the armed forces, sensitive foreign policy and the system’s ideological coherence. Not a day-to-day chief executive: the node where religious legitimacy, military sway and key appointments meet. From there, lines run to the military apparatus, the electoral filter and the civilian executive.
The military arc: IRGC, Artesh and militias
The IRGC and Artesh both defend the state but carry different weight in domestic politics and regional posture. Under the IRGC sit the Quds Force —external lines— and the Basij —territory and social control. In crises, these branches often outpace the civilian machine: hence the chart splits them as military sub-branches.
Religious supervision and the constitution
The Guardian Council and Assembly of Experts anchor the system in normative interpretation and institutional succession. One filters laws and candidates; the other, in the system’s design, watches the very center of power. As you read, the graph dims the military branch and lights the one that “translates” ideology into veto power and continuity.
The civilian executive and parliament
President, parliament and judiciary form the visible circuit in media and diplomacy. They negotiate budgets, laws and public agenda, but inside lines drawn from above: the chart shows the executive hanging from the apex—not a standalone actor. In tense periods, friction between the cabinet and opaque centers can be as telling as headlines.
Cross-cutting influence
In practice, “civilian” and “military” blur: the IRGC shapes the economy and local politics; the executive bargains with power centers that never hold press briefings. This step lights cross-links —apex, IRGC, president and Guardian Council— to read the system as a network, not silos.
A reading for 2026 and beyond
Headline names change; the analytic question is who sits in which node and which line carries orders today. This map is a static compass for following news without getting lost in chronology. Refresh your reading when alliances shift—the skeleton of the graph remains.
