About a year before this Alexander had read a book by the German mystic Franz von Baader, _On the Necessity Produced by the Revolution for a New and More Intimate Connection between Religion and Politics_. Under its influence he had formed a vague project for uniting the Christian monarchs of Europe in a mysterious alliance, which was to be in a very special manner commended to the protection of God; but at Vienna he had been obliged to give up all thoughts of carrying this project into effect. Now he discussed it with Madame de Krüdener. She entered into it eagerly, declaring that she herself had already, by the grace of God, conceived the very same idea. And who dare say that it is impossible or even unlikely that such an idea as this, _the plan of the Holy Alliance_, should have originated in the brain of a poor, silly woman, whose head had been turned by the amours of her youth and the religious enthusiasm of her later years? It is, as a matter of fact, more than probable that Europe and civilisation owe their thanks to her for it. A man who is distinctly inclined to undervalue her influence, and who is wrong where he denies it, Queen Louisa of Prussia's beloved brother, the Grand Duke of Mecklenburg-Strelitz, writes: "Madame de Krüdener never exercised the smallest influence over my angelic sister of Prussia, nor yet over the King, her husband, who judged this lamentably famous woman perfectly correctly. Of the Emperor Alexander she had, on the contrary, taken such complete possession that the Holy Alliance, which he proposed and succeeded in forming, may be regarded as entirely her work; you may be sure that I should not say this unless I were certain of it."
Some days after her arrival in Paris, Alexander said to Madame de Krüdener: "I am leaving France; but before my departure I shall publish a manifesto, acknowledging our gratitude to God the Father, the Son, and the Holy Ghost, for His protection, and calling on all nations to unite in common submission to the Gospel." With these words he handed her a paper. It was the draft of the compact between the three sovereigns. Capefigue, who actually saw this document, writes: "I have lying before me the rough draft of the compact; it is from beginning to end in the Emperor Alexander's handwriting, with corrections by Madame de Krüdener. The words _The Holy Alliance_ are written by that extraordinary woman." Thus even the name is of her devising. She chose it with a reference to the prophecies of the end of the world in the Book of the Prophet Daniel.
