Umberto II of Italy
Cascais's history as a popular seaside resort originated in the 1870s, when King Luís I of Portugal and the Portuguese royal family made the seaside town their residence every September, thus also attracting members of the Portuguese nobility, who established a summer community there. Cascais is known for the many members of royalty who have lived there, including King Edward VIII of the United Kingdom, when he was the Duke of Windsor, King Juan Carlos I of Spain, and King Umberto II of Italy. Exiled Cuban president Fulgencio Batista was also once a resident of the municipality. The Casino Estoril inspired Ian Fleming's first James Bond novel "Casino Royale".
