Zawisza Czarny of Garbow ( 1379 – 12 June 1428), also known as Zawisza the Black, of Sulima coat of arms, was a Polish knight and nobleman who served as a commander and diplomat under Polish king Władysław II Jagiełło and Hungarian-Bohemian king Sigismund of Luxembourg. During his life, he was regarded as a model of knightly virtues and was renowned for winning multiple tournaments. His nickname is due to his black hair and his custom-made, black armour which is kept at the Jasna Góra Monastery. Origin Zawisza was born in Stary Garbów, Kingdom of Poland (in modern south-eastern Poland), into a local noble family (of the Sulima), his father Mikołaj being the castellan of Konary-Sieradz (konarsko-sieradzki), while his mother was named Dorota. He had two younger brothers: Jan called "Farurej", the starost of Spisz; and Piotr called "Kruczek". In 1397, Zawisza married Barbara of the Piława clan, the niece of Bishop of Kraków Piotr Wysz, and they had four sons. 1410–1419 Briefly in the service of the Teutonic Order, he soon renounced it, and in 1410 he took part in the Battle of Grunwald on the Polish side.

As one of six diplomats that represented the Polish Kingdom and King Władysław II at the Council of Constance, he was one of very few supporters of Jan Hus, and consequently strongly opposed his condemnation and subsequent execution for heresy. In 1416 he participated in a tournament at Perpignan in which he defeated the well-known knight John II of Aragon and Navarre. The following year, he became the starosta of Kruszwica. In 1419 he went to Sigismund again, as a deputy of King Władysław II, to ask for the hand of Sophia of Bavaria, the widow of Sigismund's brother Wenceslaus of Bohemia. Subsequently, Zawisza participated in the Hussite Wars on the side of King Sigismund. During Sigismund's
