# Republic
A state in which the head of state is not a hereditary monarch but is elected, appointed, or selected through some non-hereditary process. Etymology: Latin *res publica*, "public matter" — government as a public concern rather than a private/dynastic possession.
## Defining feature
A republic is defined *negatively* in modern usage: any state without a monarch. This makes "republic" a head-of-state classification rather than a complete regime description. Republics can be democratic (Germany, India), authoritarian (Russia, China — formally republics, substantively authoritarian), one-party (China, Vietnam), or theocratic (Iran — Islamic Republic). To know how a republic actually functions, you also need to know:
- Its position on the **democratic-authoritarian** axis (free/fair elections? civil liberties? rule of law?)
- Its **executive-legislative structure** (parliamentary, presidential, or semi-presidential)
- Its **state-society relationship** (federal vs unitary, lay vs theocratic, etc.)
## Variants by executive-legislative structure
- **[[Parliamentary Republic]]** — executive (PM/cabinet) accountable to and drawn from the legislature; head of state (president) ceremonial or limited. Examples: Germany, Italy, India, Ireland, Israel.
- **[[Presidential Republic]]** — president is both head of state and head of government, separately elected from the legislature. Examples: US, Brazil, Mexico, Indonesia, South Korea.
- **Semi-presidential republic** — president (popularly elected) coexists with a PM accountable to parliament; both have meaningful power. Examples: France, Russia (formally; substantively authoritarian), Portugal, Romania.
- **One-party republic** — formal republican structure but no competitive elections. Examples: China, Vietnam, Cuba, North Korea (with monarchical succession patterns despite the formal label).
## Other variants
- **Federal republic** — power split between national and subnational governments (US, Germany, Brazil, India)
- **Unitary republic** — sovereignty concentrated at the national level (France, Japan)
- **Islamic republic** — formal republic with sharia as supreme law and clerical institutions overseeing political organs (Iran is the paradigmatic case)
## Distinguishing from democracy
A common conflation in American political discourse, encouraged by movement-conservative slogans like "we're a republic, not a democracy," treats "republic" and "democracy" as opposites. Political-science usage is clearer:
- **Republic** = a head-of-state form (no monarch)
- **Democracy** = a legitimacy mechanism (popular sovereignty through free/fair elections)
The US is *both* — a democratic republic. The "republic, not democracy" framing typically borrows the Federalist-era distinction between *direct* democracy (Athenian-style) and *representative* democracy, but treating that as an opposition between "republic" and "democracy" misuses both terms.
## Historical lineage
- **Roman Republic** (509-27 BCE) — the foundational reference for the term and the paradigm case of the mixed constitution (see [[Ancient Rome]] and its founding law, The Twelve Tables); ended with the principate under [[Augustus]] (see [[Caesarism]])
- **Italian city-state republics** (Florence, Venice, Genoa, etc., medieval through early modern)
- **Dutch Republic** (1581-1795)
- **English Commonwealth** (1649-1660; brief)
- **United States** (1776/1788–) — first large-scale modern federal republic
- **French First Republic** (1792-1804) and successors
Madison's *Federalist No. 10* argues for the *extended* republic (large geography + many factions) as a check on majority faction — a foundational text in modern republican thought. Cross-link: [[Federalist Papers]].
