Marie Louise (Maria Ludovica Leopoldina Franziska Theresia Josepha Lucia; 12 December 1791 – 17 December 1847) was Duchess of Parma from 11 April 1814 until her death in 1847. She was Napoleon's second wife and as such Empress of the French and Queen of Italy from their marriage on 2 April 1810 until his abdication on 6 April 1814.
As the eldest child of Francis II, Holy Roman Emperor and Emperor of Austria, and his second wife, Maria Theresa of Naples and Sicily, Marie Louise grew up during a period marked by ongoing and unceasing conflict between Austria and revolutionary France. A series of military defeats at the hands of Napoleon Bonaparte had inflicted a heavy human toll on Austria and led Francis to dissolve the Holy Roman Empire. The end of the War of the Fifth Coalition resulted in the marriage of Napoleon and Marie Louise in 1810, which ushered in a brief period of peace and friendship between Austria and the French Empire, much like prior alliances between the Austrian and French Royal family. Marie Louise agreed to the marriage despite being raised to despise France. She bore Napoleon a son, styled the King of Rome at birth, who briefly succeeded him as Napoleon II. Marie Louise's son was later titled Duke of Reichstadt.
