Extraordinary sejm in Warsaw 1642.
Sejm was convened, in form of an extraordinary one, in December 1641. The pre-sejm sejmiks were held in January of 1642. Krzysztof na Baksztach Zawisza, the Grand Lithuanian Scriptor and the starosta [“starostwo” was a Polish term for eldership office] of Mińsk, was elected the marshal. During the proceedings, proceeded rather smoothly, the tax matters were dealt with, mostly with intention to pay off the army for its service under military command of hetman Stanisław Koniecpolski against Kossacks and Tatars. The constitution was adopted on the, so-called, Tribunal of Radom, destined to control national treasury expenses.
