Example Input: Question: Who was the leader of Solidarity in 1991? Passage:The 1991 Polish parliamentary election was held on 27 October 1991 to elect deputies to both houses of the National Assembly. The 1991 election was notable on several counts. It was the first parliamentary election to be held since the formation of the Third Republic, the first entirely free and competitive legislative election since the fall of communism, the first completely free legislative election of any sort since 1928, and only the fifth completely free election in all of Polish history. Due to the collapse of the Solidarity movement's political wing, the 1991 election saw deep political fragmentation, with a multitude of new parties and alliances emerging in its wake. Low voting thresholds within individual constituencies, along with a five percent national threshold allocated to a small portion of the Sejm, additionally contributed to party fragmentation. As a result, 29 political parties gained entry into the Sejm and 22 in the Senate, with no party holding a decisive majority. Two months of intense coalition negotiations followed, with Jan Olszewski of the Centre Agreement forming a minority government along with the Christian National Union, remnants of the broader Center Civic Alliance, and the Peasants' Agreement, with conditional support from Polish People's Party, Solidarity and other minor parties.

Rudolph was vested with the Bohemian throne, however contested by his maternal uncle Henry of Gorizia, Duke of Carinthia and husband of Wenceslaus' sister Anne. When several Bohemian nobles elected Henry King of Bohemia, Albert I placed his brother-in-law under the Imperial ban and marched against Prague.
