It was true enough that Rudolph hardly seemed a formidable personage.  The Utraquists and Bohemian Brothers, making up nearly the whole population of the country, were just extorting religious liberty from their unlucky master in his very palace and at the point of the knife.  The envoy of Matthias was in Paris demanding recognition of his master as King of Hungary, and Henry did not suspect the wonderful schemes of Leopold, the ferret in the rabbit warren of the duchies, to come to the succour of his cousin and to get himself appointed his successor and guardian.

Nevertheless, the Emperor’s name had been used to protest solemnly against the entrance into Dusseldorf of the Margrave Ernest of Brandenburg and Palatine Wolfgang William of Neuburg, representatives respectively of their brother and father.

The induction was nevertheless solemnly made by the Elector-Palatine and the Landgrave of Hesse, and joint possession solemnly taken by Brandenburg and Neuburg in the teeth of the protest, and expressly in order to cut short the dilatory schemes and the artifices of the Imperial court.

Henry at once sent a corps of observation consisting of 1500 cavalry to the Luxemburg frontier by way of Toul, Mezieres, Verdun, and Metz, to guard against movements by the disbanded troops of the Archdukes, and against any active demonstration against the possessory princes on the part of the Emperor.

The ‘Condominium’ was formally established, and Henry stood before the world as its protector threatening any power that should attempt usurpation.  He sent his agent Vidomacq to the Landgrave of Hesse with instructions to do his utmost to confirm the princes of the Union in organized resistance to the schemes of Spain, and to prevent any interference with the Condominium.

He wrote letters to the Archdukes and to the Elector of Cologne, sternly notifying them that he would permit no assault upon the princes, and meant to protect them in their rights.  He sent one of his most experienced diplomatists, de Boississe, formerly ambassador in England, to reside for a year or more in the duchies as special representative of France, and directed him on his way thither to consult especially with Barneveld and the States-General as to the proper means of carrying out their joint policy either by diplomacy or, if need should be, by their united arms.

Troops began at once to move towards the frontier to counteract the plans of the Emperor’s council and the secret levies made by Duchess Sibylla’s husband, the Margrave of Burgau.  The King himself was perpetually at Monceaux watching the movements of his cavalry towards the Luxemburg frontier, and determined to protect the princes in their possession until some definite decision as to the sovereignty of the duchies should be made.

Meantime great pressure was put upon him by the opposite party.  The Pope did his best through the Nuncius at Paris directly, and through agents at Prague, Brussels, and Madrid indirectly, to awaken the King to a sense of the enormity of his conduct.
