Monaco, a microstate on the French Riviera in Western Europe, borders France on three sides and the Mediterranean Sea on the other side. It has an area of .78 square miles / 2 km square, making it the second-smallest country in the world after Vatican City. Monaco’s succession follows male-preference cognatic primogeniture – a female can succeed if she has no living brothers and no deceased brothers who left surviving legitimate descendants.
The House of Grimaldi descends from Otto Canella, a 12th-century Genoese statesman, and takes its name from his son Grimaldo Canella. Grimaldo had a son Oberto, known as “Oberto, son of Grimaldo” or “Oberto Grimaldi,” making him the first of the family known to use the surname of Grimaldi.
In 1297, François Grimaldi dressed a Franciscan monk, seized the Rock of Monaco. His cousin Rainier I, Lord of Cagnes was the first Grimaldi ruler of the area now known as Monaco. However, there have been several periods of occupation by Genoa, Milan, and France. The first rulers were Lords of Monaco. From 1612 onward, the rulers were Sovereign Princes. Monaco has had one Sovereign Princess, Louise Hippolyte, who reigned for ten months in 1731 before she died from smallpox.
