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.
City-state
The Principality of Monaco is an independent city-state. Monaco-Ville (the ancient fortified city) and Monaco's well-known area Monte Carlo are districts of a continuous urban zone, not distinct cities, though they were three separate municipalities ("communes") until 1917. The Principality of Monaco and the city of Monaco (each having specific powers) govern the same territory. Though they maintain a small military, they would still have to rely on France for defence in the face of an aggressive world power.
