# A Vienna proxy marriage on 19 April 1770 completes Marie-Antoinette’s Habsburg–Bourbon alliance before the Versailles rite

Date: 1770

## The fact

Versailles and Britannica print a Vienna proxy marriage in April 1770 ahead of the 16 May Versailles ceremony. Maria Theresa’s court officers share the diplomatic file. Later revolutionary slogans are not 1770.

It is one event.

## Context

[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.

Habsburg–Bourbon alliance marriage under Maria Theresa and Louis XV’s diplomacy; officers and ambassadors share the instrument.

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 proxy-then-Versailles marriage sequence.

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 proxy as alliance paperwork is a cohesion path. It is not a rebate of 1793.

## What is established and what is not

Established: April 1770 Vienna proxy in the 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 merge with the 16 May Versailles ceremony row. 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.
