The Sejm was the parliament of Poland for four centuries from the 15th until the late 18th century. It was one of the primary elements of the democratic governance in the Kingdom of Poland and the Polish-Lithuanian Commonwealth.
Composed of Polish nobility, each member had the power to veto any decision made by the body, a principle known as liberum veto.
Sejm in 1632[]
When war broke out between the Commonwealth and the USE, the Sejm gave the grand hetman Stanislaw Koniecpolski money and resources to combat the Swedish/USE incursion.
Despite giving the grand hetman the necessary supplies to combat the threat, Lukasz Opalinski states that the Sejm tends to be idiotic, greedy and fragmented. The Sejm spends more of the country's treasury to fits its own needs. Also, the Polish nobles did not send their private armies to aid in the defense of the nation. Instead, the nobility ordered their armies to sit on their lands and to ward off potential threats to their territories.
