The results of the upheaval which accompanied the extinction of the Yaghello dynasty assumed definite shape under the first two kings of the Swedish Vasa dynasty, Sigismund III. (1588-1632) and Vladislav IV. (1632-1648). The elective character of royalty made the latter dependent on the Shlakhta, which practically ruled the country, subordinating parliamentary legislation to the aristocratic and agricultural interests of their estate, and almost monopolizing the posts of voyevodas, starostas, and other important officials. At the same time the activity of the Jesuits strengthened the influence of clericalism in all departments of life. To eradicate Protestantism, to oppress the Greek Orthodox "peasant Church," and to reduce the Jews to the level of an ostracized caste of outlaws--such was the program of the Catholic reaction in Poland. To attain these ends draconian measures were adopted against the Evangelists and Arians.[55] The members of the Greek Orthodox Church were forced against their will into a union with the Catholics, and the rights of the "dissidents," or non-conformists, were constantly curtailed. The Jesuits, who managed to obtain control over the education of the growing generation, inoculated the Polish people with the virus of clericalism. The less the zealots of the Church had reason to expect the conversion of the Jews, the more did they despise and humiliate them. And if they did not altogether succeed in restoring the medieval order of things, it was no doubt due to the fact that the structure of the Polish state, with its irrepressible conflict of class interests, did not allow any kind of system to take firm root. "Poland subsists on disorders," was the boast of the political leaders of the age. The "golden liberty" of the Shlakhta degenerated more and more. It became a weapon in the hands of the higher classes to oppress the middle and the lower classes. It led to anarchy, it undermined the authority of the Diet, in which a single member could impose his veto on the decision of the whole assembly (the so-called _liberum veto_), and resulted in endless dissensions between the estates. On the other hand, one must not forget that, while this division of power was disastrous for Poland, the absolute concentration of power after the pattern of Western Europe, in the circumstances then prevailing, might have proved even more disastrous. Under a system of monarchic absolutism, Poland might have become, during the period of the Catholic reaction, another Spain of Philip II. Disorder and class strife saved the Polish people from the "order" of the Inquisition and the consistency of autocratic hangmen.
