Direct Democracy (Polish: "Demokracja Bezpośrednia" ) is a Polish political party founded in 2012.
 Its goal is to change the Polish political system by moving it closer to the political concept of direct democracy.
Ekipa (en.
 "team", English title: Prime Minister) is a Polish political drama TV series created and directed by Agnieszka Holland, aired from 13 September 2007 until 6 December 2007 (canceled due to low ratings) on Polsat.
 Ekipa is the second Polish political fiction series after the 1980s miniseries The Career of Nicodemus Dyzma.
The Renaissance in Poland (Polish: "Renesans, Odrodzenie" ; literally: the Rebirth) lasted from the late 15th to the late 16th century and is widely considered to have been the Golden Age of Polish culture.
 Ruled by the Jagiellonian dynasty, the Crown of the Kingdom of Poland (from 1569 part of the Polish–Lithuanian Commonwealth) actively participated in the broad European Renaissance.
 The multi-national Polish state experienced a period of cultural growth thanks in part to a century without major wars – aside from conflicts in the sparsely populated eastern and southern borderlands.
 The Reformation spread peacefully throughout the country (giving rise to the Polish Brethren), while living conditions improved, cities grew, and exports of agricultural products enriched the population, especially the nobility ("szlachta") who gained dominance in the new political system of Golden Liberty.
Zgromadzenie Przyjaciół Konstytucji Rządowej (in English, also variously rendered as Association of Friends of the (Governing) Constitution, Society of Friends of the Government Ordinance, Society of Friends of the Constitution, Assembly of Friends of the Government Constitution) was the first modern Polish political party (with a charter and organizational discipline), formed in May 1791, shortly after the adoption of the Constitution of May 3, 1791, by the efforts of the Patriotic Party.
 The purpose of the Friends of the Constitution was to defend the reformed political system and to introduce further reforms.
Political Consultative Committee (Polish: "Polityczny Komitet Porozumiewawczy" , "PKP") was the beginning of the political arm of the Polish Secret State in occupied Poland during World War II.
 It was formed on 26 February 1940 by several Polish political parties continuing their activities underground (Socialist Party, People's Party, National Party and Labor Party).
 The parties wanted to tighten the cooperation so that they could have more influence over the newly created Association of Armed Struggle (ZWZ) meant by the Polish government in exile as the main unified organization of the Polish resistance.
 In April 1940 the government in exile recognized the Committee as the country's political representation.
The ideas of the Age of Enlightenment in Poland were developed later than in Western Europe, as the Polish bourgeoisie was weaker, and szlachta (nobility) culture (Sarmatism) together with the Polish-Lithuanian Commonwealth political system (Golden Liberty) were in deep crisis.
 The period of Polish Enlightenment began in the 1730s–40s, peaked in the reign of Poland's last king, Stanisław August Poniatowski (second half of the 18th century), went into decline with the Third Partition of Poland (1795) – a national tragedy inspiring a short period of sentimental writing – and ended in 1822, replaced by Romanticism.
Democratization (or democratisation) is the transition to a more democratic political regime.
 It also refers to substantive political changes moving in a democratic direction.
 It may be the transition from an authoritarian regime to a full democracy, a transition from an authoritarian political system to a semi-democracy or transition from a semi-authoritarian political system to a democratic political system.
 The outcome may be consolidated (as it was for example in the United Kingdom) or democratization may face frequent reversals (as it has faced for example in Argentina).
 Different patterns of democratization are often used to explain other political phenomena, such as whether a country goes to a war or whether its economy grows.
 Democratization itself is influenced by various factors, including economic development, history, and civil society.
 The ideal result from democratization is to ensure that the people have the right to vote and have a voice in their political system.
Golden Liberty (Latin: "Aurea Libertas" ; Polish: "Złota Wolność" , Lithuanian: "Auksinė laisvė" ), sometimes referred to as Golden Freedoms, Nobles' Democracy or Nobles' Commonwealth (Polish: "Rzeczpospolita Szlachecka" or "Złota wolność szlachecka", Latin: "aureă lībertās" ) was a unique political system in the Kingdom of Poland and, after the Union of Lublin (1569), in the Polish–Lithuanian Commonwealth.
 Under that system, all nobles ("szlachta"), regardless of rank or economic status, were considered to have equal legal status and enjoyed extensive legal rights and privileges.
 The nobility controlled the legislature (the "Sejm" — the Polish parliament) and the Commonwealth's elected king.
Zebrzydowski's rebellion (Polish: "rokosz Zebrzydowskiego" ), or the Sandomierz rebellion (Polish: "rokosz sandomierski" ), was a "rokosz" (semi-legal rebellion) in the Polish–Lithuanian Commonwealth against King Sigismund III Vasa.
 The rokosz, formed on 5 August 1606 by Mikołaj Zebrzydowski, Jan Szczęsny Herburt, Stanisław Stadnicki, Aleksander Józef Lisowski and Janusz Radziwiłł in Stężyca and Lublin, was caused by the growing dissatisfaction with the King among the nobility (the "szlachta").
 In particular, the rebels disapproved of the King's efforts to limit the power of the nobles, his attempts to weaken the "Sejm" (the Polish parliament) and to introduce a hereditary monarchy in place of the elective one.
 The rebellion (1606–1608) ended in the defeat of the rebels.
 Despite the failure to overthrow the King, the rebellion firmly established the dominance of the "szlachta" over the monarch in the Polish–Lithuanian political system.
The privileges of the "szlachta" (Poland's nobility) formed a cornerstone of "Golden Liberty" in the Kingdom of Poland and, later, in the Polish-Lithuanian Commonwealth.
 Most of the privileges were granted between the late 14th and early 16th centuries.
 By the end of that period, the "szlachta" had succeeded in garnering numerous privileges, empowering themselves and limiting the powers of the monarch to an extent unprecedented elsewhere in Europe at the time.

Question: Between what two centuries were the Szlachta pirveleges, which formed the cornerstone of the Polish political system, granted?
Answer: 14th and early 16th centuries
