Monaco has been ruled by the House of Grimaldi since 1297 when Francesco Grimaldi of Genoa in Italy and his men captured the fortress protecting the Rock of Monaco while dressed as Franciscan monks. The ruler was known as Lord of Monaco until 1612 when the Council of Monaco recognized Honoré II as Sovereign Prince of Monaco. For more information about Lords of Monaco, see Rulers of Monaco.
The first parish church in Monaco was built sometime between 1247 and 1322 and was dedicated to St. Nicholas of Myra, the patron saint of sailors. Over the years, the Lords and Sovereign Princes of Monaco along with the people of Monaco generously gave funds to decorate and enlarge the Church of Saint Nicholas.
Prince Charles III (reigned 1856-1889) decided to build a new and larger building on the original site of the Church of Saint Nicholas. The original church was destroyed in 1874 and the first stone of the new building was laid in 1875. The new Cathedral of Monaco was dedicated to Our Lady of the Immaculate Conception with Saint Nicholas and Saint Benoît as secondary patron saints. Although the new building was only two-thirds completed, the first services were held in 1886. The cathedral was inaugurated in 1903 and consecrated in 1911. The current cathedral was built over the areas of the previous church and the old cemetery so that the sovereign princes and consorts originally buried at the Church of Saint Nicholas are now buried in the Cathedral of Monaco. All but two of Monaco’s sovereign princes and many of the consorts are buried at The Cathedral of Monaco. The Princely Family of Monaco is Roman Catholic.

Charlotte Louise Juliette Louvet was born on September 30, 1898, the illegitimate daughter of Louis II and Marie Juliette Louvet, a cabaret singer.

To prevent this from happening, a law was passed recognizing Charlotte as Louis II’s daughter and as a member of the princely family. Later legislation made Charlotte legitimate, allowed her father to adopt her, and gave her the surname Grimaldi and the title Duchess of Valentinois for life. Charlotte was, in effect, her father’s heiress presumptive. In March 1920, Charlotte married Count Pierre de Polignac.
