Meanwhile the internal complications in the southern Slav provinces of Austria-Hungary were growing formidable. Ever since the summer of 1908 arrests had been going on among the members of the Croato-Serb coalition, who were accused of favouring the subversive Pan-Serb movement. The press of Austria-Hungary magnified the importance of this agitation in order to justify abroad the pressing need for the formal annexation of Bosnia and Hercegovina. The fact was that, though immediate danger to the monarchy as a result of the Pan-Serb agitation was known not to exist, yet in the interests of Austrian foreign policy, the Serbs had to be compromised in the eyes of Europe, the Croato-Serb coalition within the Dual Monarchy had to be destroyed to gratify Budapest in particular, and the religious and political discord between Croat and Serb, on which the foundation of the power of Austria-Hungary, and especially that of Hungary, in the south rested, and which was in a fair way of being eliminated through the efforts of the coalition, had to be revived by some means or other. It is not possible here to go into the details of the notorious Agram high treason trial, which was the outcome of all this. It suffices to say that it was a monstrous travesty of justice which lasted from March till October 1909, and though it resulted in the ostensible destruction of the coalition and the imprisonment of many of its members, it defeated its own ends, as it merely fanned the flame of nationalistic feeling against Vienna and Budapest, and Croatia has ever since had to be governed virtually by martial law. This was followed in December 1909 by the even more famous Friedjung trial. In March 1909 Count Achrenthal had begun in Vienna a violent press campaign against Serbia, accusing the Serbian Government and dynasty of complicity in the concoction of nefarious designs and conspiracies against the integrity of Austria-Hungary. This campaign was thought to be the means of foreshadowing and justifying the immediate military occupation of Serbia. Unfortunately its instigator had not been sufficiently particular as to the choice of his tools and his methods of using them. Among the contributors of the highly tendencious articles was the well-known historian Dr. Friedjung, who made extensive use of documents supplied him by the Vienna Foreign Office. His accusations immediately provoked an action for libel on the part of three leaders of
