Senate of Poland in the context of "Sejm of the Polish–Lithuanian Commonwealth"

Parliamentary elections were held in Poland on 4 June 1989 to elect members of the Sejm and the recreated Senate, with a second round on 18 June. They were the first free and fair elections in the country since the communist government abandoned its monopoly of power in April 1989 and the first elections in the Eastern Bloc that resulted in the communist government losing power.

Not all seats in the Sejm were allowed to be contested, but the resounding victory of the Solidarity opposition in the freely contested races (the rest of the Sejm seats and all of the Senate) paved the way to the end of communist rule in Poland. Solidarity won all of the freely contested seats in the Sejm, and all but one seat in the Senate, which was scored by a government-aligned nonpartisan candidate. Most crucially, the election served as evidence of widespread dissatisfaction with the government. In the aftermath of the election, Poland became the first country of the Eastern Bloc in which democratically elected representatives gained real power. Although the elections were not entirely democratic, they led to the formation of a non-communist government led by Tadeusz Mazowiecki and a peaceful transition to democracy in Poland and elsewhere in Central and Eastern Europe.

The szlachta (Polish pronunciation: [ˈʂlaxta] ; Lithuanian: šlėkta; lit. 'nobility') , the nobles, were the noble estate of the realm in the Kingdom of Poland, the Grand Duchy of Lithuania, and the Polish–Lithuanian Commonwealth. It was the dominating social class in the Kingdom of Poland and the Polish-Lithuanian Commonwealth, which was exercising political rights and power. Szlachta as a class differed substantially from the feudal nobility of Western Europe. The estate was officially abolished in 1921 by the March Constitution.

The origins of the szlachta are obscure and the subject of several theories. The szlachta secured substantial and increasing political power and rights throughout its history, beginning with the reign of King Casimir III the Great between 1333 and 1370 in the Kingdom of Poland until the decline and end of the Polish–Lithuanian Commonwealth in the late 18th century. Apart from providing officers for the army, its chief civic obligations included electing the monarch and filling honorary and advisory roles at court that would later evolve into the upper legislative chamber, the Senate. The szlachta electorate also took part in the government of the Commonwealth via the lower legislative chamber of the Sejm (bicameral national parliament), composed of representatives elected at local sejmiks (local szlachta assemblies). Sejmiks performed various governmental functions at local levels, such as appointing officials and overseeing judicial and financial governance, including tax-raising. The szlachta assumed various governing positions, including voivode, marshal of voivodeship, castellan, and starosta.

The Sejm (Polish: [sɛjm] ), officially known as the Sejm of the Republic of Poland (Polish: Sejm Rzeczypospolitej Polskiej), is the lower house of the bicameral parliament of Poland.

The Sejm has been the highest governing body of the Third Polish Republic since the transition of government in 1989. Along with the upper house of parliament, the Senate, it forms the national legislature in Poland known as National Assembly (Polish: Zgromadzenie Narodowe). The Sejm comprises 460 deputies (singular poseł, rarely deputowany), elected every four years by universal ballot. The Sejm is presided over by a speaker, the Marshal of the Sejm (Marszałek Sejmu).

The parliament of Poland is the bicameral legislature of Poland. It is composed of an upper house (the Senate) and a lower house (the Sejm). Both houses are accommodated in the Sejm and Senate Complex in Warsaw. The Constitution of Poland does not refer to the Parliament as a body, but only to the Sejm and Senate.

Members of both houses are elected by direct election, usually every four years. The Sejm has 460 members, while the Senate has 100 senators. To become law, a bill must first be approved by both houses, but the Sejm can override a Senate refusal to pass a bill.

Castellans of the Polish–Lithuanian Commonwealth were the lowest rank of territorial official who could sit in the Senate of Poland. Their numbers varied over time and with the shifting borders of the Commonwealth.

In the Kingdom of Poland and later in the Polish–Lithuanian Commonwealth, Castellans (Polish: Kasztelan) usually deferred to the higher ranking Voivodes (wojewoda), excepting three Distinguished Castellans of the cities of Trakai, Vilnius, and of Kraków - who ranked higher than the Voivodes.

Parliamentary elections were held in Poland on 9 October 2011. All 460 members of the Sejm and 100 senators of the Senate were elected. The ruling Civic Platform (PO) won a plurality of seats and Tusk became the first Polish prime minister to be appointed for a second consecutive term since the fall of communism. Both the Civic Platform and its junior partner, the Polish People's Party (PSL), agreed to continue their governing coalition after the election.

The General Sejm (Polish: Sejm walny, also translated as the General Parliament) was the parliament of the Kingdom of Poland. It had evolved from the earlier institution of Curia Regis (King's Council) and was one of the primary elements of democratic governance in the Polish dominion.

Initially established in 1386, it officially functioned as a bicameral diet since the formation of the Senate in 1493. The Sejm was composed of members of the royal council or king's court (the royal court, who played the largest role), provincial crown offices such as castellans, voivodes and higher nobility or magnates (the aristocratic element represented by the senate, upper house), members of the nobility who did not hold any crown offices and city council representatives (the democratic element represented by the lower house or chamber of deputies). These were the so-called three parliamentary states: the king, the senate and the parliamentary chamber. 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 of Poland and the Seimas of the Grand Duchy of Lithuania were merged into the Sejm of the Polish–Lithuanian Commonwealth by the Union of Lublin in 1569.
