Biography
He was born in Drużbin, Poddębice County, Poland. In 1626, Jakub Zadzik was instrumental in convincing the Sejm in Toruń to increase taxes in order to generate funds for the war against Sweden and to create a commission for reformation of the military treasury.

He negotiated the Treaty of Altmark in 1629 and the Treaty of Sztumska Wieś in 1635 with Sweden, which ended the Polish-Swedish War, and the Treaty of Polanów with Russia in 1634, ending the Smolensk War.

He was a dedicated Catholic and a supporter of the Counter-Reformation. In 1638 he succeeded in closing the Polish Brethren center in Raków. He often opposed Władysław IV Waza, especially his actions designed to regain the throne of Sweden and strengthen the powers of the monarchy by means of military action.

Zadzik sponsored the Cracow Bishops' Palace in Kielce, now a museum.
