Jakub Sobieski (May 5, 1590 – June 23, 1646) was a Polish noble, parliamentarian, diarist, political activist, military leader and father of King John III Sobieski. He was the son of castellan and voivode Marek Sobieski and Jadwiga Snopkowska.
Sobieski was educated in Kraków and Paris. He was a famed orator and parliamentarian. He participated in the military expedition (Dymitriads) against Russia in 1617-1618 (wounded during the assault of Moscow), and was a member of the War Council (Rada wojenna) of King W?adys?aw IV. He took part in negotiations with Muscovy in the Truce of Deulino in 1618. Subsequently he fought in the Chocim expedition against the Ottoman Empire in 1621, and the expedition against Abazy Pasa in 1633. He was one of the negotiations with Sweden in the Treaty of Stuhmsdorf (Sztumska Wie?) in 1635.
After his marriage to Zofia Teofillia Dani?owicz his wealth increased significantly, as Zofia brought in her inheritance after the ?ó?kiewski family and part of the Dani?owski family estates, including ?ó?kiew Castle.
He was courtier since 1617, Krajczy of the Crown since 1626, Podczaszy of the Crown since 1636,voivode of Belz Voivodeship since 1638 and of Ruthenian Voivodeship since 1641 and castellan of Kraków since 1646.Starost of Trembowla, Krasnystaw, Jaworów, Stryj, Ka?usz, Bar and Gniewo. Elected Deputy to seven Sejms between 1623 and 1632, as Sejm Marshal he led the ordinary Sejm in Warsaw on January 24 - March 5, 1623 and on January 27 - March 10, 1626, the extraordinary Sejm in Warsaw on June 27 - July 18, 1628 and the Election Sejm in Warsaw on September 24 - November 15, 1632.
He was considered by his contemporaries a wise and honorable person. Member of many commissions and diplomatic bodies, he often acted as a mediator or as a guardian of orphaned children. In politics, he usually supported king's plans, but was also a defender of the nobility rights and religious tolerance.
During the Chocim expedition in 1621 he wrote a diary called Commentariorum chotinensis belli libri tres (Pami?tnik wojny chocimskiej - Diary of the Chocim War), which was published in 1646 in Danzig. It was used by Wac?aw Potocki as a basis for his epic poem, Transakcja wojny chocimskiej (The Progress of the War of Chocim).
He authored Commentariorum Chotinensis belli libri tres (1646) and instructions for his sons journeying to Kraków (1640) and France (1645) which are seen as a prime example of liberal education of that era.
