# Louis-Joseph, dauphin of France, is born on 22 October 1781 as Marie-Antoinette’s first surviving son

Date: 1781

## The fact

Versailles and Britannica print 22 October 1781 as the birth of Louis-Joseph-Xavier-François, the dauphin. Physicians and household officers share the medical-court record.

It is one event.

## Context

Marie-Thérèse’s 1778 birth and Louis-Charles’s 1785 birth are neighbouring child rows.

Marie-Antoinette’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

Bourbon succession anxiety after years without a dauphin; court and European diplomats treated the birth as public news.

Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers are the surviving public file.

## Evidence and sources

Château de Versailles and Britannica independently date the dauphin’s 1781 birth.

Official or archival record: Château de Versailles — Marie-Antoinette (https://en.chateauversailles.fr/discover/history/great-characters/marie-antoinette; Établissement public du château, du musée et du domaine national de Versailles).

## Significance

A documented royal heir birth is a dynastic continuity path under the [democratic-resilience](/drivers/democratic-resilience) driver as succession stability, not a modern election.

## What is established and what is not

Established: 22 October 1781 birth in the palace/encyclopedia file. Not established: unique welfare coefficients for later France.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Marie-Antoinette.

They are not a public rating.

The driver `democratic-resilience` is attached because the mechanism named in Significance follows from this instrument, not because a standing list of welfare headings needed another tick. Marie-Antoinette did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A portrait or conventional bust is not this mechanism. Allegation, reconstruction, and established occurrence stay distinct. Do not merge with the 1789 death of Louis-Joseph. Keep the carrier date of later English distinct from the received historical year stored in the date field. Do not read a later English edition as a recovered autograph of Marie-Antoinette.
