Napoleon was then engaged in making great preparations for a war with Austria, and it was important for Austria to secure the alliance of Prussia, her great rival, with whom she had never been on truly friendly terms, since both aimed at ascendency in Germany. Frederick William III. was then on the throne of Prussia, having two great men among his ministers,--Von Stein and Hardenberg; the former at the head of financial affairs, and the latter at the head of the foreign bureau. To the more important post of Berlin, Metternich was therefore sent. He found great difficulty in managing the Prussian king, whose jealousy of Austria balanced his hatred of Napoleon, and who therefore stood aloof and inactive, indisposed for war, in strict alliance with Russia, who also wanted peace. The Czar Alexander I., who had just succeeded his murdered father Paul, was a great admirer of Napoleon. His empire was too remote to fear French encroachments or French ideas. Indeed, he started with many liberal sentiments. By nature he was kind and affectionate; he was simple in his tastes, truthful in his character, philanthropic in his views, enthusiastic in his friendships, and refined in his intercourse,--a broad and generous sovereign. And yet there was something wanting in Alexander which prevented him from being great. He was vacillating in his policy, and his judgment was easily warped by fanciful ideas. "His life was worn out between devotion to certain systems and disappointment as to their results. He was fitful, uncertain, and unpractical. Hence he made continual mistakes. He meant well, but did evil, and the discovery of his errors broke his heart. He died of weariness of life, deceived in all his calculations," in 1825.
