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.

Context

Marie-Antoinette’s documented role is bounded by other offices and collaborators named in the sources below.

Lived 1755–1793; queen consort from 1774. 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.

Why it matters

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

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
