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.
List of heirs to the Monegasque throne
This list begins with the sole reign of Catalan, Lord of Monaco, whose father Jean (or Giovanni) I first set out a law of succession in his will in 1454. Until 1427 Monaco was effectively a condominium with up to three rulers simultaneously; after Jean I became sole ruler he sought to keep the throne for one person, of the Grimaldi family. This succession included the stipulation that while a woman could inherit if there were no male heirs in her immediate family, she must marry a Grimaldi cousin to keep the inheritance in the family. The first Lady of Monaco, Claudine Grimaldi, abdicated in favour of her cousin and later married him; a later Princess of Monaco, however, would defy this law. It was ignored, however, and the throne continued to pass to their descendants, who adopted the name Grimaldi in place of their own.
