The thought of a German Empire had arisen. At the headquarters at Versailles the project was discussed, and it was thought that King Wilhelm should be the Emperor. This was the object of both Bismarck's and the Crown Prince's labours. With regard to details, however, their views were at complete variance. Friedrich desired a German unified state; he thought of the Emperor as surrounded by responsible ministers. The German Princes would, of course, govern within the limits of their countries, but their power must be considerably curtailed; and those who would not voluntarily make sacrifices for the federated fatherland must be made to do so by force. The Chancellor, on the other hand, was of opinion that the Princes ought to be protected as far as was possible, and that they ought to retain their rights. He greatly desired that the Empire might arise from a free agreement on their side. "If only the South Germans would take the decisive step!" he often said. [21] The King of Prussia had up to the last moment little desire to accept the Imperial crown. Should it, however, prove to be necessary, he wished that it might take place on the invitation of the King of Bavaria. Ludwig was pressingly invited to come to Versailles. Shortly before this he had, through a fall from his horse, twisted his ankle, with the result that it caused him excessive pain to sit on horseback. Still, for a short time, he considered the question of proceeding thither. Bismarck's secretary, Busch, tells us in his memoirs that it was thought to summon a congress of Princes on the 11th of October, and that it was hoped that the King of Bavaria would be present. The historical rooms of Versailles were to be placed at his disposal, as it was considered that he would appreciate this mark of attention. "I never thought that I should come to play the part of a major-domo at Trianon," said Bismarck. "If only the King will come!" But the King did not come. On the 19th of October the Ministers of Würtemberg, Hesse, and Baden went to Versailles. On the 20th the King of Bavaria sent his Ministers Bray, Pranckh, and Lutz to the headquarters. It appeared at first as if the negotiations would be crowned with success; the desire that South Germany should offer King Wilhelm the Imperial crown seemed to be nearing its fulfilment. The leaders of the national party developed a restless energy. Large meetings of the people accepted resolutions which made for the same end. The press warmly advocated a German Empire. The greatest enthusiasm in favour of the project was shown in Prussia and in Baden; but it spread from land to land.
