People's Republic of Poland in the context of "Mieczysław Jagielski"

Presidential elections were held in Poland on 25 November 1990, with a second round on 9 December. They were the first direct presidential elections in the history of Poland, and the first free presidential elections since the May Coup of 1926. Before World War II, presidents were elected by the Sejm. From 1952 to 1989—the bulk of the Communist era—the presidency did not exist as a separate institution, and most of its functions were fulfilled by the State Council of Poland, whose chairman was considered the equivalent of a president.

There were six candidates who successfully managed to register - Solidarity chairman Lech Wałęsa, Canadian entrepreneur Stanisław Tymiński, Prime Minister Tadeusz Mazowiecki, Members of the Sejm Włodzimierz Cimoszewicz and Roman Bartoszcze, and anti-communist oppositionist Leszek Moczulski. Despite for a long time coming first in opinion polls, Tadeusz Mazowiecki's campaign failed to convince voters to his side, and he did not enter the runoff, coming third in the first round. Stanisław Tymiński came second in a large upset unforeseen by every political force in the country, and, being seen by other candidates as a liar and opportunist, managed to unite both the postcommunist and Solidarity establishments against him. In the second round, Wałęsa won almost 75% of the vote, the largest electoral victory for a free election in Polish political history.

Inter-Enterprise Strike Committee (or Inter-Factory Strike Committee, Polish: Międzyzakładowy Komitet Strajkowy, MKS) was an action strike committee formed in Gdańsk Shipyard, People's Republic of Poland on 16 August 1980. It was led by Lech Wałęsa and others and is famous for issuing the 21 demands of MKS on 17 August, that eventually led to the Gdańsk Agreement and creation of Solidarity.

Operation Vistula (Polish: Akcja Wisła; Ukrainian: Опера́ція «Ві́сла») was the codename for the 1947 forced resettlement of close to 150,000 Ukrainians, Rusyns, Boykos, and Lemkos from the southeastern provinces of postwar Poland to the Recovered Territories in the west of the country.The action was carried out by the Soviet-installed Polish communist authorities to remove material support to the Ukrainian Insurgent Army. The Ukrainian Insurgent Army continued its guerrilla activities until 1947 in Subcarpathian and Lublin Voivodeships with no hope for any peaceful resolution; Operation Vistula brought an end to the hostilities.

In a period of three months beginning on 28 April 1947 and with Soviet approval and aid about 141,000 civilians residing around Bieszczady and Low Beskids were forcibly resettled to former German territories, ceded to Poland at the Yalta Conference at the end of World War II.

Polonization or Polonisation (Polish: polonizacja; Belarusian: паланізацыя, romanized: pałanizacyja; Ukrainian: полонізація, romanized: polonizatsiya; Lithuanian: polonizacija; Samogitian: puoluonėzacėjė) is the acquisition or imposition of elements of Polish culture, in particular the Polish language. This happened in some historic periods among non-Polish populations in territories controlled by or substantially under the influence of Poland.

Like other examples of cultural assimilation, Polonization could be either voluntary or forced. It was most visible in territories where the Polish language or culture was dominant or where their adoption could result in increased prestige or social status, as was the case with the nobilities of Ruthenia and Lithuania. To a certain extent, political authorities have administratively promoted Polonization, particularly during the interwar period and in the period following World War II.

The magnates of Poland and Lithuania (Polish: magnateria, Lithuanian: magnatai) were an aristocracy of Polish-Lithuanian nobility (szlachta) that existed in the Crown of the Kingdom of Poland, in the Grand Duchy of Lithuania and, from the 1569 Union of Lublin, in the Polish–Lithuanian Commonwealth, until the Third Partition of Poland in 1795.

The magnate social class arose around the 16th century and, over time, gained more and more control over Commonwealth politics. The most powerful magnates were known as "little kings" due to the extent of their power and independence. Their influence diminished with the Third Partition of Poland (1795), which ended the Commonwealth's independent existence, and came to an end with the Second World War and the communist-ruled People's Republic of Poland.

Żydowski Związek Wojskowy (ŻZW, Polish for Jewish Military Union, Yiddish: יידישע מיליטערישע פֿאראייניקונג, romanized: Yidishe Militerishe Fareynikung) was an underground resistance organization operating during World War II in the area of the Warsaw Ghetto, which fought during the Warsaw Ghetto Uprising and 1944 Warsaw Uprising. It was formed, primarily of former officers of the Polish Army, in late 1939, soon after the start of the German occupation of Poland.

Due to the ŻZW's close ties with the Armia Krajowa (AK), which was closely linked to the Polish Government in Exile, after the war the Soviet-dependent People's Republic of Poland suppressed publication of books and articles on ŻZW. Its role in the uprising in the ghetto was downplayed, in favour of the larger, more socialist Żydowska Organizacja Bojowa (Jewish Fighting Organization).

The Border Agreement between Poland and the USSR of 16 August 1945 established the borders between the Soviet Union (USSR) and the People's Republic of Poland. It was signed by the Provisional Government of National Unity (Tymczasowy Rząd Jedności Narodowej) formed by the Polish communists. According to the treaty, Poland officially accepted the ceding its pre-war Eastern territory to the USSR (Kresy) which was decided earlier in Yalta already. Some of the territory along the Curzon line, established by Stalin during the course of the war, was returned to Poland. The treaty also recognised the division of the former German East Prussia and ultimately approved the finalised delimitation line between the Soviet Union and Poland: from the Baltic Sea, to the border tripoint with Czechoslovakia in the Carpathians. The agreement entered into force on 5 February 1946.

Jürgen Stroop (born Josef Stroop, 26 September 1895 – 6 March 1952) was a German SS commander and perpetrator of the Holocaust during the Nazi era, who served as SS and Police Leader in occupied Poland and Greece from 1942-1943 (in Poland) and 1943-1944 (in Greece). He held the rank of SS-Gruppenführer und Generalleutnant der Polizei from 1942-1945 (equivalent to a Heer Generalleutnant/Lt-Gen in the Wehrmacht). He led the suppression of the Warsaw Ghetto Uprising in 1943 with German Troops consisted of Heer Troops including Waffen-SS and the Order Police battalions and wrote the Stroop Report, a twelve-page account of the operation annexed with many original documents and pictures. Following the defeat of Germany, Stroop was prosecuted during the Dachau Trials and convicted of murdering nine U.S. prisoners of war. After his extradition to Poland, Stroop was tried, convicted, and executed for crimes against humanity.
