Army-Parliament Dual Sovereignty

Definition

Army-Parliament dual sovereignty is an unstable order in which a representative legislature claims civil authority while the military force that created or protects the regime retains an independent claim to define, purge, or replace that legislature.

Current Synthesis

The English Republic depended on both the purged House of Commons and an army that was more religiously and politically radical. Because the army had removed MPs and enabled regicide, Parliament could not fully subordinate it; because military officers lacked an accepted civilian mandate, the army could not turn coercive power into durable constitutional legitimacy.

Oliver Cromwell temporarily mediated the conflict through personal authority, but repeated dissolutions reproduced rather than solved it. After his death, Richard Cromwell’s rapid fall and renewed army-junta rule made the unresolved dual sovereignty visible again.

Key Claims

• Military creation of a legislature’s governing space can compromise civilian supremacy from the beginning.
• Ideological differences between army and Parliament turn institutional rivalry into a dispute over the revolution’s meaning.
• Personal leadership can suppress dual sovereignty without constitutionalizing it.
• Legislative purges narrow representative legitimacy even when justified as revolutionary necessity.
• Succession exposes whether authority belongs to an office, an assembly, or armed force.

Evidence

Founding conflict

• 333: The Republic of Britain: Life under Cromwell connects Pride’s Purge, the regicide, and the new regime to an alliance between a narrowed Parliament and a more radical army.

Personal containment

• 333: The Republic of Britain: Life under Cromwell describes Cromwell’s repeated removal of MPs and expanding executive authority.

Succession failure

• 333: The Republic of Britain: Life under Cromwell traces Richard Cromwell’s fall, army-junta rule, and George Monck’s intervention for Parliament.

Counterevidence & Qualifications

Neither “the army” nor “Parliament” was internally uniform. Returning MPs moderated the Commons, officers disagreed, and constitutional experiments changed across the decade. Dual sovereignty is an analytical compression, not a claim that exactly two coherent institutions controlled every phase.

What Changed

• Created a constitutional model for the English Republic’s recurring military–legislative authority conflict.

Related Concepts

• Republican Founding Without Settlement - founding gap that allowed rival authority claims to persist.
• Regicide as Republican Founding - irreversible act enabled by military intervention but insufficient to settle sovereignty.
• Providential Governance Failure - personal decision model that could override institutional compromise.
• Restoration Contingency - collapse pathway opened when no institution controlled succession.
