プロイセンの王
Prince Frederick was twenty-eight years old when his father Frederick William I died and he ascended to the throne of Prussia. Before his accession, Frederick was told by D'Alembert, "The philosophers and the men of letters in every land have long looked upon you, Sire, as their leader and model." Such devotion, consequently, had to be tempered by political realities. When Frederick ascended the throne as the third "King in Prussia" in 1740, his realm consisted of scattered territories, including Cleves, Mark, and Ravensberg in the west of the Holy Roman Empire; Brandenburg, Hither Pomerania, and Farther Pomerania in the east of the Empire; and the Kingdom of Prussia, the former Duchy of Prussia, outside of the Empire bordering the Polish–Lithuanian Commonwealth. He was titled "King in Prussia" because his kingdom included only part of historic Prussia; he was to declare himself "King of Prussia" after acquiring most of the rest in 1772.
