Louis II, Prince of Monaco
On 26 June 1922, Prince Albert I died in Paris. Louis Grimaldi ascended to the throne as Louis II, Prince of Monaco. While his reign never achieved the grandeur of his father, Louis II left an indelible imprint on the tiny principality. In 1924 the Monaco Football Club was formed and in 1929, the first Grand Prix of Monaco automobile race was held, won by Charles Grover (aka "Williams") driving a Bugatti painted in what would become the famous British racing green color. He collected artefacts belonging to Napoleon I which are now assembled and displayed in the Napoleon Museum attached to the Royal Palace in Monte Carlo.
Monaco
Of interest to numismatists, in Monaco the euro was introduced in 2002, having been preceded by the Monégasque franc. In preparation for this date, the minting of the new euro coins started as early as 2001. Like Belgium, Finland, France, the Netherlands, and Spain, Monaco decided to put the minting date on its coins. This is why the first euro coins from Monaco have the year 2001 on them, instead of 2002, like the other countries of the Eurozone that decided to put the year of first circulation (2002) on their coins. Three different designs were selected for the Monégasque coins. However, in 2006, the design was changed after the death of ruling Prince Rainier to have the effigy of Prince Albert.
