# Marie-Antoinette marries the dauphin at Versailles on 16 May 1770 as a completed Habsburg-French alliance ceremony

Date: 1770

## The fact

Versailles and Britannica print 16 May 1770 as the Versailles marriage that sealed the Austrian alliance after a proxy in Vienna. Mercy-Argenteau and Maria Theresa share the diplomatic file. Later revolutionary hatred is not 1770.

It is one event.

## Context

Du Barry’s household conflict in the same years is a neighbouring court path, not a twin of the rite.

[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.

Lived 1755–1793; queen consort from 1774. Household officers, Austrian diplomats, the king, and later Revolutionary clerks share the file. Cake is a later slogan, not a sourced utterance. The Diamond Necklace is allegation and image. Fiscal crisis is not stored as her unique coefficient. Complex contribution is required.

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’s Marie-Antoinette page and Britannica independently describe the 1770 marriage.

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 completed dynastic marriage as alliance is a cohesion path. It is not a rebate of 1793.

## What is established and what is not

Established: 16 May 1770 ceremony in the public palace and encyclopedia file. Not established: unique later-war coefficients.

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 `social-cohesion` 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 treat 1770 as 1789. 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.
