The last decades of the independent Commonwealth existence were characterized by intense reform movements and far-reaching progress in the areas of education, intellectual life, arts and sciences, and especially toward the end of the period, evolution of the social and political system.
[4] The level of economic prosperity in the Commonwealth was largely determined by its agricultural production, but for the fundamental transformation that the country experienced in the second half of the 18th century, the changes taking place in the cities and within the industrial sphere were of crucial importance.
[8] As in many other European countries, the Enlightenment in the Polish-Lithuanian state was a period of great advancement of the burgher class, the upper ranks of which consisted of urban business and professional people, whose economic position was growing stronger and who sought corresponding expansion of political standing and influence.
The burgher estate had now found itself in a situation favorable in comparison with that of their brethren in Silesia, or in the strictly government-controlled areas appropriated by Prussia after the First Partition, which were also subjected to German colonizing activity at the expense of Polish urban people.
[9] The early capitalist development brought new elements of social stratification in the cities, including the emergent during the last decade of independence intelligentsia, the banker, manufacturing and trade elites, and the fast-growing plebeian propertyless groups, the nascent proletariat.
Members of this group massively supported reformist postulates of the Great Sejm, promoted the French Revolution ideals, helped distribute political literature, and were the faction that matured and became indispensable during the Insurrection.
Members of this group possessed little or no property and were rapidly becoming degraded, because under the changing political and social circumstances the work they had traditionally provided for the wealthy (service in private magnate armies, staffing local legislative assemblies, servant duties in manorial estates etc.)
In Cracow the reform was directed by Kołłątaj, who expanded several departments, especially in the fields of mathematics and the physical sciences, stressed practical applications of academic subjects and introduced the Polish language as the main teaching medium.
[11] Many other schools were directly under the guidance of the Education Commission, whose approved teaching programs emphasized the exact sciences and the national language, history and geography; Latin became restricted and theology was eliminated.
The Polish-Lithuanian state found itself among the leading European countries regarding the educational organization and quality at the academic and secondary levels; the Commission deeply influenced the prevailing social attitudes of not only its own time, but also well into the 19th century.
Naruszewicz completed his History of the Polish Nation only to 1386, but also left a collection of highly valuable for historical research source materials and dealt critically with the more recent destructive tendencies in szlachta's politics.
The Czartoryskis rivaled the royal court in their desire to constructively influence and reform the Commonwealth's nobility (still to be controlled by the magnate class), but operating in a different setting, they chose alternate ways of social persuasion and artistic expression.
The first full-fledged Polish plays were the patriotic The Return of the Deputy by Julian Ursyn Niemcewicz (1790) and the folklore-inspired Krakowiacy and Górale (names of ethnographic (folk) groups of southern Lesser Poland) by the long-term theater director Wojciech Bogusławski.
The Protestant Holy Trinity Church in Warsaw (architect Szymon Bogumił Zug) was patterned after the Pantheon of Rome and the classical style was imitated in many burgher residencies in cities and provincial palaces of the nobility.
Russia emerged form the Seven Years' War as the main victorious power, and, aligned with Prussia, became decisively important in the affairs of the weak, subjected to foreign transgressions and incapable of independent functioning Commonwealth.
Andrzej Zamoyski then presented a program of constructive reforms, that included the majority rule in parliament, establishment of a permanent executive council (as recommended by Stanisław Konarski) and turning of the Republic's highest offices into collective organs.
Parliamentary rules were made more functional, deputies were no longer bound by instructions issued by the local assemblies that delegated them (sejmiks), majority voting was imposed in matters involving the treasury and economics (which weakened the unanimity requirement enforced thus far by the liberum veto procedure).
The Familia party at that time rejected religious reform for the fear of antagonizing the masses of fanatically intolerant nobility and of encouraging regional political dissent in Royal Prussia and the Grand Duchy of Lithuania, when they were trying to strengthen the dysfunctional central government.
The Ukrainian uprising, led by the Cossack commanders Ivan Gonta and Maksym Zalizniak, was ruthlessly suppressed by the Polish Crown and Russian forces, but resulted in disturbances in other parts of the Republic of Both Nations and prevented those, who were to continue the confederate warfare, from appealing to large scale peasant support.
The middle nobility fought for national independence, but under conservative assumptions of inviolability of their own privileged position as well as of that of the Catholic Church, which limited the appeal of the entire undertaking (the army of the nobility-dominated uprising was mostly non-noble and the cities sympathized with the King).
[20] At the end of 1770 the confederates, led by the French adviser General Charles François Dumouriez and the insurgency's best commander Kazimierz Pułaski, attempted to establish a permanent line of defense along the banks of the upper Vistula, but they were able to hold onto Lanckorona and Tyniec only for a significant period.
The Empire, distracted militarily at the time of its major war with Turkey, decided to agree to the reduction of the territory of Russia's troublesome Polish ally, promoted by Frederick II the Great of Prussia, which led to the First Partition of the Polish–Lithuanian Commonwealth.
Wybicki wrote in 1777 the Patriotic Letters, where he expounded the reform movement's main themes: strengthening of the central government and the new postulated relationships among the social classes, including in particular improvements in the condition of townspeople and peasants.
Among the military and diplomatic moves and maneuvering taking place, Poland was encouraged to engage in closer cooperation with Prussia and to confront Russia, which encountered interest and willingness on the part of some circles and participants in the Commonwealth politics.
There they signed the "Act of Unification of the Cities" and formed the Black Procession, which headed for the Royal Castle and handed in their postulates of greatly increased political and economic rights for residents of towns to the King and the Sejm.
This new council consisted of the king as its presiding officer, the primate, five ministers (of police, internal affairs, foreign interests, war and treasury), and also, with an advisory vote only, the marshal of the sejm and the heir to the throne.
His intention was to utilize his American experience, combine military operations by a regular army with those of informal and irregular popular forces, based on peasant and urban masses, hoping to substitute their great numbers and motivation for the inevitable deficiencies in equipment and training.
[32] During advanced preparations, the uprising conspiracy was uncovered in Warsaw by the Russian ambassador Iosif Igelström, who arrested activists and moved to accelerate the reduction of the Commonwealth armed forces, already ordered by the Grodno Sejm.
[33] Tadeusz Kościuszko assumed dictatorial powers, obliging himself to use it to regain national self-sufficiency, defend the country's borders and promote general freedom, deferring systemic reform to a more opportune time.
The Provisional Council was formed there by moderates and people connected to the royal court, but they soon encountered stiff opposition from Warsaw masses directed by the Jacobin Club, established on April 24 for the ostensible purpose of strictly adhering to the "undertaking of Kościuszko".
