full_context: Document 1: Sejm of the Polish–Lithuanian Commonwealth: The general sejm (Polish: "sejm walny" , also translated as the full or ordinary sejm) was the bicameral parliament of the Polish–Lithuanian Commonwealth. It was established by the Union of Lublin in 1569 from the merger of the Sejm of the Kingdom of Poland and the Seimas of Grand Duchy of Lithuania, Ruthenia and Samogitia. It was one of the primary elements of the democratic governance in the Commonwealth (see Golden Liberty). The sejm was a powerful political institution and the king could not pass laws without the approval of that body.
Document 2: Confederation (Poland): A konfederacja (] , "confederation") was an "ad hoc" association formed by Polish-Lithuanian "szlachta" (nobility), clergy, cities, or military forces in the Polish-Lithuanian Commonwealth for the attainment of stated aims. A konfederacja often took the form of an armed rebellion aimed at redressing perceived abuses or trespasses of some (e.g. royal) authority. Such "confederations" acted in lieu of state authority or to force their demands upon that authority. They could be seen as a primary expression of direct democracy and right of revolution in the Commonwealth, and as a way for the nobles to act on their grievances and against the state's central authority.
Document 3: Sejm of the Duchy of Warsaw: Sejm of the Duchy of Warsaw (Polish: "Sejm Księstwa Warszawskiego" ) was the parliament of the Duchy of Warsaw. It was created in 1807 by Napoleon, who granted a new constitution to the recently created Duchy. It had limited competences, including having no legislative initiative. It met three times: for regular sessions in 1809 and 1811, and for an extraordinary session in 1812. In the history of Polish parliament, it succeeded the Sejm of the Polish-Lithuanian Commonwealth and was followed by the Sejm of the Congress Poland.
Document 4: Silent Sejm: Silent Sejm (also "Dumb Sejm" and literally "Mute Sejm", Belarusian: Нямы сойм ; Polish: "Sejm Niemy" ; Lithuanian: "Nebylusis seimas" ) is the name given to the session of the Sejm (parliament) of the Polish-Lithuanian Commonwealth of 1 February 1717 held in Warsaw. A civil war in the Commonwealth was used by the Russian Tsar Peter the Great as an opportunity to intervene as a mediator. It marked the end of Augustus II of Poland's attempts to create an absolute monarchy in Poland, and the beginning of the Russian Empire's increasing influence and control over the Commonwealth.
Document 5: List of szlachta: The szlachta (Polish: "szlachta" , ) was a privileged social class in the Kingdom of Poland. The term "szlachta" was also used for the Lithuanian nobility after the union of the Grand Duchy of Lithuania with Poland as the Polish-Lithuanian Commonwealth (Union of Lublin, 1569) and for the increasingly Polonized nobilities of territories controlled by the Polish-Lithuanian Commonwealth, including Ducal Prussia and the Ruthenian lands.
Document 6: Union of Lublin: The Union of Lublin (Polish: "unia lubelska" ; Lithuanian: "Liublino unija" ) was signed July 1, 1569, in Lublin, Poland, and created a single state, the Polish–Lithuanian Commonwealth. It replaced the personal union of the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania with a real union and an elective monarchy, since Sigismund II Augustus, the last of the Jagiellons, remained childless after three marriages. In addition, the autonomy of Royal Prussia was largely abandoned. The Duchy of Livonia, tied to Lithuania in real union since the Union of Grodno (1566), became a Polish–Lithuanian condominium.
Document 7: History of Lithuania: The history of Lithuania dates back to settlements founded many thousands of years ago , but the first written record of the name for the country dates back to 1009 AD. Lithuanians, one of the Baltic peoples, later conquered neighboring lands and established the Grand Duchy of Lithuania in the 13th century (and also a short-lived Kingdom of Lithuania). The Grand Duchy was a successful and lasting warrior state. It remained fiercely independent and was one of the last areas of Europe to adopt Christianity (beginning in the 14th century). A formidable power, it became the largest state in Europe in the 15th century through the conquest of large groups of East Slavs who resided in Ruthenia. In 1385, the Grand Duchy formed a dynastic union with Poland through the Union of Krewo. Later, the Union of Lublin (1569) created the Polish–Lithuanian Commonwealth that lasted until 1795, when the last of the Partitions of Poland erased both Lithuania and Poland from the political map. Afterward, the Lithuanians lived under the rule of the Russian Empire until the 20th century.
Document 8: Sejm: The Sejm of the Republic of Poland ( ; Polish: "Sejm Rzeczypospolitej Polskiej" ) is the lower house of the Polish parliament. It consists of 460 deputies (posłowie, literally "envoys", in Polish) elected by universal ballot and is presided over by a speaker called the "Marshal of the "Sejm" of the Republic of Poland" ("Marszałek Sejmu Rzeczypospolitej Polskiej"). In the Kingdom of Poland, ""Sejm"" referred to the entire three-chamber parliament of Poland, comprising the lower house (the Chamber of Envoys; Polish: "Izba Poselska" ), the upper house (the Senate; Polish: "Senat") and the King. It was thus a three-estate parliament. Since the Second Polish Republic (1918–1939), ""Sejm"" has referred only to the lower house of the parliament; the upper house is called the "Senat Rzeczypospolitej Polskiej" ("Senate of the Republic of Poland").
Document 9: Military of the Polish–Lithuanian Commonwealth: The military of the Polish–Lithuanian Commonwealth evolved from the merger of the armies of the Kingdom of Poland and the Grand Duchy of Lithuania following the 1569 Union of Lublin, which formed the Polish–Lithuanian Commonwealth. The army was commanded by the Hetmans of the Polish–Lithuanian Commonwealth. The most unique formation of the army was the heavy cavalry in the form of the Polish winged hussars. The Polish–Lithuanian Commonwealth Navy never played a major role in the military structure, and ceased to exist in the mid-17th century.
Document 10: Seimas of the Grand Duchy of Lithuania: Seimas ("Sejm", "Sojm", Belarusian: Сойм ) was an early parliament in the Grand Duchy of Lithuania. It was active from 1445 to 1569, when it was officially abolished by the Union of Lublin. The Seimas was an irregular gathering of the Lithuanian nobility, called as needed by the Grand Duke or during an interregnum by the Lithuanian Council of Lords (an early government). The meetings would usually last one or two weeks. Seimas gradually evolved from a meeting of the most powerful magnates to a full legislative institution representing all of the nobility. The Seimas was not the main political player as it was overshadowed by the Council of Lords. The Union of Lublin created a new state, the Polish–Lithuanian Commonwealth, and joined the Seimas of Lithuania with Sejm of Poland into one Sejm of the Polish–Lithuanian Commonwealth. However, the Seimas continued to convene under the name of Lithuanian Convocation. In total there were 40 Seimas and 37 Convocations.
Document 11: Sejm of the Kingdom of Poland: The general sejm (Polish: "sejm walny" , also translated as the full or ordinary sejm) was the parliament of Kingdom of Poland. It had evolved from the earlier institution of "wiec". It was one of the primary elements of the democratic governance in the Kingdom of Poland. The sejm was a powerful political institution, and from early 16th century, the Polish king could not pass laws without the approval of that body. The Sejm and the Seimas of the Grand Duchy of Lithuania was merged into the Sejm of the Polish–Lithuanian Commonwealth by the Union of Lublin in 1569.
Document 12: Leičiai: Leičiai (singular: leitis) were a distinct social group of the Lithuanian society in the early Grand Duchy of Lithuania subordinate to the Lithuanian ruler or the state itself. Leičiai were native to the Lietuva Land and formed the core of the Lithuanian society in the pre-state era and during the establishment of the state. Leičiai made up the majority of the military-economic staff of the state: they enforced state authority in the periphery, protected state borders, and performed various other war-related functions, such as breeding riding horses. By the 15th and 16th centuries, leičiai were in decline, already losing some of their functions and prestige, and they disappeared as a social class after the implementation of the Wallach Reform.
Document 13: Interrex (Poland): The institution of interrex existed in the Crown of the Kingdom of Poland, whose ruling classes liked to view their Republic (Rzeczpospolita) or Commonwealth as an heir to Roman republican traditions. The Commonwealth's monarch holding a double title of the Two Nations King of Poland and Grand Duke of Lithuania entered upon their office by free election ("wolna elekcja"), which often led to a relatively long interregnum. Since 1572, the role of interrex traditionally fell to the Archbishop of Gniezno and Primate of Poland of the Roman Catholic Church. The Archbishop could nominate a replacement (traditionally he would choose the bishop of Kujawy).
Document 14: Grodno Sejm: Grodno Sejm (Polish: "Sejm grodzieński" ; Belarusian: Гарадзенскі сойм ; Lithuanian: "Gardino seimas" ) was the last Sejm (session of parliament) of the Polish–Lithuanian Commonwealth. The Grodno Sejm, held in fall of 1793 in Grodno, Grand Duchy of Lithuania (now Hrodna, Belarus) is infamous because its deputies, bribed or coerced by the Russian Empire, passed the act of Second Partition of Poland. The Sejm started on 17 June and ended on 23 November 1793. It ratified the division of the country in a futile attempt to prevent its subsequent complete annexation two years later in the 1795 Third Partition of Poland.
Document 15: Union of Horodło: The Union of Horodło or Pact of Horodło was a set of three acts signed in the town of Horodło on 2 October 1413. The first act was signed by Władysław II Jagiełło, King of Poland, and Vytautas, Grand Duke of Lithuania. The second and third acts were composed by the Polish nobility (szlachta) and Lithuanian boyars respectively. The union amended the earlier Polish–Lithuanian unions of Krewo and Vilnius–Radom. Politically, Lithuania received more autonomy as, after the death of Vytautas, the Lithuanian nobles could choose another Grand Duke instead of passing the title to Władysław II Jagiełło or his heir. However, culturally, Lithuania and Poland grew closer. Lithuania adopted Polish institutions of castellans and voivodes. Catholic Lithuanian nobles and church officials were granted equal rights with the Polish nobles and clergy. Forty-seven selected Lithuanian nobles were adopted by Polish families and granted Polish coats of arm. Thus the union signified the beginnings of Polonization of Lithuanian culture and the rise of the Lithuanian nobility. It was one of the major steps towards the modernization and Europeanization of Lithuania.
