Whatever we call “treason”—Hochverrat, trahison, velezrada, veleizdaja, felségsértés—it has been a constant phenomenon in human history. The “traitor,” the individual who breaks a major bond of trust, has emerged in every era and is usually treated as a pariah in society. At the most significant treason trial of the late Habsburg monarchy, that of fifty-three Serbs in Zagreb in 1909, the main defense lawyer Hinko Hinković began his concluding speech with a typical legal adage: that treason was “the most loathsome thing” imaginable. Down the centuries, he said, humanity had singled out two types of traitors. First, there were those who betrayed God, best personified in Judas Iscariot. Second, there were traitors to the nation such as the Spartan Ephialtes who, according to Herodotus, fatally betrayed his homeland to the Persians at Thermopylae in 480 BCE. While both types were “repulsive and terrible,” Hinković quickly opined that the latter—the national traitor—was really the most terrible. However, with an eye on the Serbs he was defending, he added that some national treasons were not actually directed against the nation. For where national aspirations did not mesh with state aspirations, or where the state was not the same as the homeland (otačbina)—there, a deed that the state might consider treasonous could be viewed as a heroic, patriotic act by the nation. In other words, treason could be interpreted as liberation from oppression, and numerous examples might be cited in this regard from recent Habsburg history, not least the way that the Magyars were now able to celebrate and memorialize the traitor-liberator Lajos Kossuth.
