Albert II, Prince of Monaco
Prince Albert II is one of the wealthiest royals in the world, with assets valued at more than $1 billion, which include land in Monaco and France. Although Prince Albert does not own the Prince's Palace of Monaco, he does own shares in the "Société des bains de mer de Monaco", which operates Monaco's casino and other entertainment properties in the principality.

Within a year of their marriage, the couple's only child (Louis) was born, but Mary, from the hills of Scotland, disliked Monaco and everything Mediterranean. While Albert was away fighting in the Franco-Prussian war, she left Monaco permanently. The couple divorced and their marriage was annulled by the Church on 3 January 1880, although a special provision was made by the Vatican to allow Louis to remain legitimate in the eyes of the Church. Civilly, the marriage was dissolved on 28 July 1880 by the Order of Prince Charles III. That same year, the former Princess of Monaco remarried in Florence, Italy, to a Hungarian nobleman, Prince Tassilo Festetics von Tolna.
