Voltaire takes up paid residence at Frederick II’s Potsdam court

In July 1750 Voltaire entered Frederick II’s household at Potsdam/Sanssouci on a royal pension. The later quarrel and 1753 departure are the same cluster’s end, not a separate republic. In the causal graph this event weakens Democratic Resilience, a driver that strengthens Having a say in government — a worsening welfare path.

Read the full account

In July 1750 Voltaire entered Frederick II’s household at Potsdam/Sanssouci on a royal pension. The later quarrel and 1753 departure are the same cluster’s end, not a separate republic.

Context

Enlightened absolutism paid for verses and conversation. It also used the guest as advertisement. Sanssouci’s museum pages and Britannica independently date the stay.

Voltaire is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.

Why it matters

Resilience-harm path via princely patronage. High confidence on the residence.

A pension is not a lettre de cachet against priests. Keep the salary visible.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

    He accepted a king’s salary and lodging. Frederick set the terms. Complex courtier-philosophe, not a Prussian minister of justice.

What the sources establish

SPSG’s Sanssouci institutional pages and Britannica independently record the 1750–53 episode.

Established: Voltaire lived as Frederick’s paid guest from 1750. Not established: that every anti-Machiavel sentence is Frederick’s policy.

Later competitions, monuments, translations, UNESCO listings, and museums are not converted into extra lifetime acts. That reading is an impact-path choice, not a property stored on the Fact itself. Confidence is stated on the impact path. A later English edition is not a recovered autograph. If a number is not in the two records named above, it is not supplied here. Confidence is stated on the impact path.
