Marriage and issue
Margherita's family announced her engagement to Robert, Archduke of Austria-Este, on 20 October 1953. They married on 28 December in Bourg-en-Bresse, Ain, France (civilly) and 29 December (religiously), in Royal Monastery of Brou. He was the second son of former Emperor Charles I of Austria and Zita of Bourbon-Parma. Robert was 38, and Margherita was 23. As the royal couple arrived for the first ceremony, hundreds of Austrians and Italians stood outside the town hall where the marriage was held. The wedding was also attended by former King Umberto II of Italy and Robert's older brother Otto of Habsburg, the claimant to the Austrian throne. At six feet tall, Margherita was, according to some witnesses, an impressive sight. She wore an ivory gown made out of satin with a long train hung from a diamond tiara.
