Jakub of Sienno
Jakub of Sienno (Polish: Jakub z Sienna) was a medieval Bishop Kraków in the years 1461–1463, Bishop of Włocławek from 1464, and then Archbishop of Gniezno from 1474. He was also a 15th-century diplomat for the Polish Crown.
Jakob was born in 1413 in Sienno, the son of Dobisław of Oleśnicy a local aristocrat of the Debno family and his wife Catherine Oleśnicka, daughter of Dymitr of Goraj. His father, Dobiesława Olesnica mala Dębno, was Count of Sandomierz.
His brothers were:
- John of Sienna Castellan of Lwów
- Dymitr of Sienna (d. 1465) Canon of Kraków
- Nicholas of Sienna (d. 1484) Archdeacon of Sandomierz
- Paul of Sienna (c. 1410–1444) the Royal Secretary
- Andrzej Sienieński (d. 1494) Chamberlain of Sandomierz
- He was also a nephew of Cardinal Oleśnicki.
As a diplomat he served as Secretary of King Vladislav Varnenchik and King Casimir IV Jagiellon. He was sent on missions to Hungary in 1442 and 1448 and in 1459 he represented the King at the Congress of Mantua.
Pope Pius II appointed him Bishop of Kraków. Unfortunately, the King had other plans and request the appointment of John Gruszczynski, consecrated on May 31, 1461. The conflict escalated with the Pope (Pius II) on 2 June 1461, threatening to excommunicate the King. The King then banished Jakub.
Eventually on 16 January 1462 the conflict was resolved through intersession of the papal legate Jerome Lando, Archbishop of Crete. In January 1463 at the Sejm in Piotrków the Kings appointee abdicated the bishopric of Kraków.
Pope Pius II compensated Jakob and he received the bishopric of Włocławek. In Włocławek and in Gniezno he installed oak pew stalls and rich liturgical equipment, and donated to the library of Kraków Academy.
