外交革命
Following the Seven Years' War and the Diplomatic Revolution of 1756, Empress Maria Theresa decided to end hostilities with her longtime enemy, King Louis XV of France. Their common desire to destroy the ambitions of Prussia and Great Britain and to secure a definitive peace between their respective countries led them to seal their alliance with a marriage: on 7 February 1770, Louis XV formally requested the hand of Maria Antonia for his eldest surviving grandson and heir, Louis-Auguste, duc de Berry and Dauphin of France.
