her seventeenth birthday, exchanged for prominent French prisoners (Pierre Riel de Beurnonville, Jean-Baptiste Drouet, Hugues-Bernard Maret, Armand-Gaston Camus, Nicolas Marie Quinette, and Charles-Louis Huguet de Sémonville) and taken to Vienna, the capital city of her cousin, the Holy Roman Emperor Francis II, and also her mother's birthplace. Exile (1795–1814) Marie-Thérèse arrived in Vienna on 9 January 1796, in the evening, twenty-two days after she had left the Temple. She later left Vienna and moved to Mitau, Courland (now Jelgava, Latvia), where her father's eldest surviving brother, the Comte de Provence, lived as a guest of Tsar Paul I of Russia. He had proclaimed himself King of France as Louis XVIII after the death of Marie-Thérèse's brother. With no children of his own, he wished his niece to marry her cousin, Louis-Antoine, Duc d'Angoulême, son of his brother, the Comte d'Artois. Marie-Thérèse agreed. Louis-Antoine was a shy, stammering young man. His father tried to persuade Louis XVIII against the marriage. However, the wedding took place on 10 June 1799 at Jelgava Palace (modern-day Latvia). The couple had no children. Life in Britain The royal family moved to Great Britain, where they settled at Hartwell House, Buckinghamshire, while her father-in-law spent most of his time in Edinburgh, where he had been given apartments at Holyrood House. The long years of exile ended with the abdication of Napoleon I in 1814, and the first Bourbon Restoration, when Louis XVIII stepped upon the throne of France, twenty-one years after the death of his brother Louis XVI. Bourbon Restoration (1814–1830) Louis XVIII attempted to steer a middle course between liberals and the Ultra-royalists led by the Comte d'Artois. He also attempted to suppress the many men who claimed to be Marie-Thérèse's long-lost younger brother, Louis XVII. Those claimants caused the princess a good deal of distress. Marie-Thérèse found her return emotionally draining and she was distrustful of the many Frenchmen who had supported either the Republic or Napoleon. She visited the site where her brother had died, and the Madeleine Cemetery where her parents were buried. The royal remains were exhumed on 18 January 1815 and re-interred in Saint-Denis Basilica, the royal necropolis of France, on 21 January 1815, the 22nd anniversary of Louis XVI's execution. In March 1815, Napoleon returned to France and rapidly began to gain supporters and raised an army in the period known as the Hundred Days. Louis XVIII fled France,
