Albert II, Prince of Monaco
As Monaco's head of state, Prince Albert II is depicted on coins, including collectors' coins, with very rare exceptions. One of the most recent examples is the €5 silver Prince Albert II commemorative coin, the first commemorative coin with his effigy on it, minted in 2008. On the obverse, the prince is depicted in profile with his name on the top of the coin. On the reverse, the Grimaldi coat of arms appears; around it, the words "Principauté de Monaco" (Principality of Monaco) also appear along with the nominal monetary value of the coin.As the prince, his official shortened title is "His Serene Highness Albert II, Sovereign Prince of Monaco"; this does not include the many other styles claimed by the Grimaldi family.
Monaco succession crisis of 1918
The duke, a descendant through a morganatic marriage of the royal family of Württemberg, was the elder son of Albert's aunt, Princess Florestine of Monaco. Although he was ineligible to inherit the crown of his patrilineal ancestors in Germany, given the line of succession to the Monegasque throne at that time, there was every likelihood that the principality would pass by lawful inheritance into Wilhelm's "German hands" upon the death of Prince Louis. However, given the bitter relations between France and Germany at that time – a socio-political legacy of the Franco-Prussian War of 1870–71 and then of World War I – France deemed it unacceptable for a country over which it had exercised "de facto" or "de jure" hegemony, intermittently since the 17th century and consistently for half a century, to fall into the hands of a German aristocrat.
