In the game's words

How to use it

The Sejm is a unique Polish building that can be built by Settlers and the Hetman in the Commerce Age. Uniquely, it combines the Capitol and the Factory, granting Poles earlier access to powerful economic upgrades. The Sejm generates resources based on your current Settler count, rewarding a booming economy. In the Industrial Age, the ‘Democracy of Nobles’ card can halve this reliance on Settlers, while the Cossacks Revolution has the option to include the Military count, too.

History

The Sejm (meaning ‘gathering’) was the bicameral parliament of the Polish-Lithuanian Commonwealth and is considered one of the earliest legislatures in Europe. The so-called ‘Golden Liberty’ system severely limited the authority of the monarch in matters of legislation, taxation, and foreign policy. Instead, it vested significant power in the roughly 10% of the population belonging to the noble ‘szlachta’ class. This democracy of nobles was eventually paralyzed by wealthy, influential Magnate families and their abuse of the destructive ‘Liberum Veto’ (Latin for ‘I freely forbid’), a rule allowing any single member to nullify an entire session. The legislative gridlock by magnates and foreign powers ultimately caused the Commonwealth's collapse and final partition in 1795. Successor states on Polish territory like the Napoleonic Duchy of Warsaw and Russian Congress Poland continued the Sejm merely for the display of legitimacy. Today, the parliaments of Poland, Lithuania, and Latvia still use names derived from the historical Sejm.
