Sejm faces the inner state issues 1618.

Sejm was convened in December 1617. The pre-sejm sejmiks were held in January and February of 1618. The sejm debated from 13 February to 27 March 1618. Krzysztof Wiesiołowski, the Lithuanian Pantler, was elected the marshal. The reason to call the sejm was the international situation: war in Livonia, increasing Turkish and Tatar threat, war with Muscovy. All of these created the need to adopt taxes. However, sejm focused its attention on inner state matters, like filling the vacancies and disputes on incompatibilia. Conscription universal was adopted.
