The ascent of the Wettin dynasty to the Polish throne, as well as the government's difficulties in procuring taxes led to a waning of previous policies of religious tolerance in Poland, and the partitions of Poland during the second half of the century led to widespread violence as the government's power faltered and various regional powers and separatist movements fought for control of the territory.
During this time period, the Jewish community of Poland would also experience the tail-end of Sabbatianism in the form of the followers of Jacob Frank, who claimed to be a successor of Sabbatai Zevi.
Although Augustus II the Strong (1697–1733), and August III Wettin (1733–1763) officially confirmed at their coronations the Jewish charters, such formal declarations were insufficient to guard the already limited rights of the Jews against the hostile elements, owing to the disorders prevailing in the kingdom.
The government was anxious only to collect from the Kahals the taxes, which were constantly being made heavier despite the Jews having not yet recovered from the ruinous events of the Cossacks' uprising and the Swedish invasion.
The szlachta and the townsfolk were increasingly hostile to the Jews, as the religious tolerance that dominated the mentality of the previous generations of the Commonwealth citizens was slowly forgotten.
Based originally on economic grounds, they were carried over into the religious arena; and it was evident that the seeds which the Jesuits had planted had finally borne fruit.
In this time of mysticism and overly formal rabbinism came the teachings of Israel ben Eliezer, known as the Baal Shem Tov, or BeShT, (1698–1760), which had a profound effect on the Jews of Eastern Europe and Poland in particular.
The following are noteworthy: Disorder and anarchy reigned supreme in Poland during the second half of the 18th century, from the accession to the throne of its last king, Stanislaus II Augustus Poniatowski (1764–1795).
The permanent council established at the instance of the Russian government (1773–1788) served as the highest administrative tribunal, and occupied itself with the elaboration of a plan that would make practicable the reorganization of Poland on a more rational basis.
One of the members of the commission, kanclerz Andrzej Zamoyski, along with others, demanded that the inviolability of their persons and property should be guaranteed and that religious toleration should be to a certain extent granted them; but he insisted that Jews living in the cities should be separated from the Christians, that those of them having no definite occupation should be banished from the kingdom, and that even those engaged in agriculture should not be allowed to possess land.
Kościuszko was decisively defeated at Battle of Maciejowice October 10, 1794; Alexander Suvorov entered Warsaw on November 8, and Polish resistance came to an end.
This regiment accomplished many deeds of valor on the field of battle and distinguished itself especially at the siege of Warsaw, nearly all its members perishing in the defence and eventual massacre of Praga, the fortified suburb of the capital.
