Sejm
lower house of Polish parliament
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 the 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).
In the Kingdom of Poland, the term Sejm referred to the entire bicameral parliament, comprising the Chamber of Deputies (Izba Poselska) and the Senate, with the King presiding. It was thus a three-estate parliament. The 1573 Henrician Articles strengthened the assembly's jurisdiction, making Poland a constitutional elective monarchy. Since the Second Polish Republic (1918–1939), Sejm has referred only to the lower house of parliament.
During the existence of the Polish People's Republic, the Sejm, then a unicameral parliament, was the nominal supreme organ of state power in the country.

Why this record matters
“Sejm” is worth following because a concise public description often conceals a longer documentary argument. Here, Sejm, lower and house provides the most credible route into that argument.

The linked authority identifier is Q98964. VIAF identifies the subject as 122508542. The Library of Congress control number is n50070334. 5 of 6 selected statements include explicit references; 2 carry qualifiers and 1 use preferred rank. The first chronological checks are 1989, 1573, 1918 and 1939.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
