What was needed for him who, overshadowing others, stood at the head of that movement from east to west?

What was needed was a sense of justice and a sympathy with European affairs, but a remote sympathy not dulled by petty interests; a moral superiority over those sovereigns of the day who cooperated with him; a mild and attractive personality; and a personal grievance against Napoleon. And all this was found in Alexander I; all this had been prepared by innumerable so-called chances in his life: his education, his early liberalism, the advisers who surrounded him, and by Austerlitz, and Tilsit, and Erfurt.

During the national war he was inactive because he was not needed. But as soon as the necessity for a general European war presented itself he appeared in his place at the given moment and, uniting the nations of Europe, led them to the goal.

The goal is reached. After the final war of 1815 Alexander possesses all possible power. How does he use it?
