About Rainier III Louis Henri Maxence Bertrand Grimaldi, Prince of Monaco
-------------------- Rainier III (Rainier Louis Henri Maxence Bertrand Grimaldi; 31 May 1923 – 6 April 2005) ruled the Principality of Monaco for almost 56 years, making him one of the longest ruling monarchs of the 20th century. Though he was best known outside of Europe for having married American actress Grace Kelly, he was also responsible for reforms to Monaco's constitution and for expanding the principality's economy beyond its traditional gambling base. Gambling accounts for only approximately three percent of the nation's annual revenue today; when Rainier ascended the throne in 1949, it accounted for more than 95 percent.
Rainier was born in Monaco, the only son of Prince Pierre of Monaco, Duke of Valentinois (né Count Pierre de Polignac) and his wife, Hereditary Princess Charlotte, Duchess of Valentinois. Born in Algeria, his mother was the only child of Prince Louis II and Marie Juliette Louvet; she was later legitimized through formal adoption and subsequently named heiress-presumptive to the throne of Monaco. His father was a half-French, half-Mexican nobleman from Brittany who adopted his wife's surname, Grimaldi, upon marriage and was made a prince of Monaco by his father-in-law. Rainier had one sibling, Princess Antoinette, Baroness of Massy, an unpopular figure generally believed to be meddlesome enough regarding her children's place in the line of succession to have forced Princess Grace to demand that she leave the country.
