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.

The Hereditary Prince(ss) of Monaco is the title given to the heir apparent or heir presumptive of the Monegasque throne, since its official creation on 15 May 1882.
