Petar Zrinski and Fran Krsto Frankopan (Francesco Cristoforo Frangipani) were ordered to the Emperor's Court. The note said that, as they had ceased their rebellion and had repented soon enough, they would be given mercy from the Emperor if they would plead for it. They were arrested the moment they arrived in
Vienna, and put on trial. They were held in
Wiener Neustadt and beheaded on April 30, 1671. Nádasdy was executed on the same day, and Tattenbach was executed later on December 1, 1671. The conspirators were first tried by the Emperor's court; after the verdict, however, they requested the exercise of their right—as nobles—to be tried by a court of their peers. Another court was assembled, of nobility from parts of the empire far from Croatia or Hungary, which also accepted the previous fatal verdict. Petar Zrinski's verdict read that he "[...] committed a greater sin than the others in aspiring to obtain the same station as His Majesty, that is, to be an independent Croatian ruler, and therefore he indeed deserves to be crowned not with a crown, but with a bloody sword." During the trial and after the execution, the conspirators' estates were pillaged, and their families scattered. The destruction of these powerful feudal families ensured that no similar event took place until the bourgeois era. Petar's wife (
Katarina Zrinska) and two of their daughters died in convents, and his son,
Ivan, died mad after a terrible imprisonment and torture. Katarina published the last letter her husband had sent to her, as a motivation to end the war with the Ottomans. The bones of Zrinski and Frankopan (Frangipani) remained in
Austria for 248 years, and it was only after the fall of the monarchy that their remains were moved to the crypt of
Zagreb Cathedral.
Legacy in Hungary Leopold I appointed a Directorium to administer Hungary in 1673, led by the
Teutonic Order Grand Master Johann Caspar von Ampringen, which replaced the
Palatine of Hungary. The new government pursued a harsh crackdown against disloyal nobles and the Protestant movement. In order to combat the perceived threat from Hungary's Protestants against the
Roman Catholics in his lands, Leopold ordered some 60,000 forced
conversions in the first two years of his reprisals for the conspiracy. In addition, 800 Protestant churches were closed down. By 1675, 41 Protestant
pastors would be
publicly executed after having been found guilty of inciting riots and revolts. in
Čakovec, Croatia The crackdown caused a number of former soldiers and other Hungarian nationals to rise up against the state in a sort of
guerilla warfare. These
kuruc ("
crusaders") began launching raids on the Habsburg army stationed within Hungary. For years after the crackdown, kuruc rebels would gather
en masse to combat the Habsburgs; their forces' numbers swelled to 15,000 by the summer of 1672. This loss was a death warrant for most Croatian noble families, which had voted in 1526 for the Habsburgs to rule in
Croatia. Without any territory to control, they eventually became a historical footnote. Only the
Zrinski and
Frankopan families stayed powerful, because their possessions were in the unconquered, western part of Croatia. At the time of the conspiracy, they controlled around 35% of civilian Croatia (another third of Croatian territory was under the emperor's direct control, as the
Military Frontier). After the conspiracy failed, these lands were confiscated by the emperor, who could grant them upon his discretion. Nothing better shows the situation in Croatia after the conspiracy than the fact that between 1527 - 1670 there were 13
bans (
viceroys) of Croatia of Croatian origin—but between 1670 and the revolution of 1848, there would be only 2 bans of Croatian nationality. The period from 1670 to the
Croatian cultural revival in the 19th century was Croatia's political dark age. From the Zrinski-Frankopan conspiracy until the
French Revolutionary Wars in 1797, no soldiers were recruited from Istria, where in the 17th century a total of 3,000 soldiers had been recruited. ==Conspirators==
