# Sophie Hélène Béatrix is born on 9 July 1786 as Marie-Antoinette’s fourth child

Date: 1786

## The fact

Britannica and Versailles print 9 July 1786 as the birth of Sophie Hélène Béatrix. Accoucheurs share the record.

It is one event.

## Context

Louis-Charles (1785) and Louis-Joseph (1781) births are neighbouring child rows.

[Marie-Antoinette](/people/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.

Court obstetrics after prior royal pregnancies; infant survival remained contingent.

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

Britannica and Versailles independently date Sophie’s July 1786 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 birth under court medical attendance is a limited health-capacity path for that household delivery.

## What is established and what is not

Established: 9 July 1786 birth. Not established: a national midwifery reform series.

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 `health-system-capacity` 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 Sophie’s 1787 death. 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.
