[Sidenote: Otto's reign in Greece] Full recognition was given to Prince Otto of Wittelsbach as King of Greece. The young prince, then in his eighteenth year, had already landed at Nauplia. He commenced his reign with a regency consisting of Bavaria's ablest ministers, Count Armandsberg, Von Maurer, and Heideck. King Louis of Bavaria commemorated the accession of his son to the throne of Greece by erecting a number of monumental buildings at Munich in imitation of the architecture of ancient Greece, and by mural paintings in the arcades of his palace garden depicting all the most famous places and incidents of the Greek struggle for independence. [Sidenote: French painters] [Sidenote: Death of Legendre] In France, a new impetus was likewise given to art. Jean Baptiste Leloir began his career as a painter of religious and historical subjects; Lecquereux, the great historical painter, stood already at the zenith of his power, and Corot's exquisite landscapes were receiving their full measure of appreciation. In French letters, this year is noted for the first appearance of Balzac's "Eugenie Grandet" and Prosper Merimee's "Double Erreur." Legendre, the great French mathematician, died during this year. [Sidenote: Treaty of Keteya] [Sidenote: Compact of Unkiarskelessi] [Sidenote: Moltke] It was the foreign policy of France to supplant Russia as mediator between Turkey and Egypt. Admiral Roussin had made it plain to the Sultan that if Syria could not be reconquered from the rebellious Mehemet Ali except by Russian forces the province was more than lost to Turkey. Accordingly, a French envoy was sent to Mehemet's victorious son, Ibrahim, with powers to conclude peace on any terms. The French suggestions were adopted on April 10, in the treaty of Keteya. The Sultan made over to his viceroy all of Syria and a part of Adana. The Egyptians consented to leave Anatolia. The Sultan took the spoliation so much to heart that he turned from France. Once more he entered into negotiations with Russia. Russian warships were permitted to enter the Dardanelles, and Russian troops camped side by side with the Turks on the east bank of the Bosphorus. A secret treaty for defence and offence was concluded between Russia and Turkey at the palace of Unkiarskelessi: The Porte undertook to close the Dardanelles to the warships of all other nations whenever Russia should be at war. Thus the entrance to the Black Sea was made practically a Russian stronghold. As soon as the purport of this treaty was apprehended it had the effect of uniting the rest of Europe against Russia--notably, France and England. Henceforth Russia's ascendency in the East was watched by the chancelleries of Europe with growing suspicion. Sultan Mahmoud set himself seriously to reorganize his army after Western models. Following the example of Mehemet Ali, he summoned foreign officers to his general staff. It was then that Moltke, the subsequent strategist of Germany, entered Turkish service.
