Le Corbusier publishes the Plan Voisin: eighteen towers on a razed right-bank Paris, sponsored as a completed urban plan
In 1925, at the Pavillon de l’Esprit Nouveau and in related publications, Le Corbusier presented the Plan Voisin: a grid of cruciform towers on a cleared right bank of Paris, with highways in the voids. In the causal graph this event strengthens Forced-Displacement Scale, a driver that strengthens People Internally Displaced by Conflict and Violence (IDMC) — a worsening welfare path.
Read the full account
In 1925, at the Pavillon de l’Esprit Nouveau and in related publications, Le Corbusier presented the Plan Voisin: a grid of cruciform towers on a cleared right bank of Paris, with highways in the voids. He did not receive a demolition warrant. Displacement is the path because the plan’s content is erasure of a living centre. Automobile patronage (Voisin) is in the name.

Context
Residents of the Marais and the right bank were the would-be displaced. Pierre Jeanneret shared the office; the signature is Le Corbusier’s public brand.
Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
Why it matters
A famous unbuilt clearance is still a displacement path as a completed idea that later housing ministries copied in spirit. High confidence on 1925 as publication; later banlieue towers are mixed reception, not this drawing.
Confidence is stated on the impact path, not hidden in adjectives. Unbuilt is not a reason to drop a published plan; UNESCO listing of other works is not this act. Mixed effects of Le Corbusier publishes the Plan Voisin: eighteen towers on a razed right-bank Paris, sponsored as a completed urban plan are separate paths.

A completed public plan to erase central Paris fabric for towers and motorways is a displacement path of high confidence on the 1925 scheme, not a unique 1925 eviction census (it was unbuilt).

What the sources establish
Fondation Le Corbusier’s portal independently hosts the architectural oeuvre including the 1920s urban plans. Britannica independently treats Plan Voisin and high-rise urbanism as his. MoMA’s artist page independently frames the modern-movement urban schemes. No unique 1925 eviction roll exists because the plan was not executed.
Established: 1925 Plan Voisin as his published Paris scheme. Not established: a unique count of flats that would have been lost, or that the City adopted it. Not a 2016 World Heritage file as the act.
Shared responsibility is part of Le Corbusier publishes the Plan Voisin: eighteen towers on a razed right-bank Paris, sponsored as a completed urban plan. Naming Le Corbusier does not delete co-authors, institutions, or later transmitters. The lag from 1925-01-01 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.
The contribution type is direct. That reading is an impact-path choice, not a property stored on the Fact itself.
