Anna of Cilli and her daughter Hedwig Jagiellon were 15th-century figures in which European country's royal family?
Anna of Cilli Anna of Cilli or Anne of Celje (  1381 – 21 May 1416) was Queen consort of Poland (1402–1416). She was the second wife of Jogaila (Władysław II Jagiełło), King of Poland and Supreme Duke of Lithuania (reigned 1387–1434). Their marriage was politically motivated to strengthen Jogaila's ties with the Piast dynasty and his claims to the Polish throne. Their marriage was rather distant and during fourteen years Anna bore only one daughter, Hedwig Jagiellon, who died without issue.
Hedwig of Kalisz Hedwig of Kalisz (Polish: "Jadwiga Bolesławówna"; 1266 – 10 December 1339) was the second of three daughters born to Bolesław the Pious and Saint Yolanda of Hungary. In 1293, Jadwiga married Władysław I the Elbow-high, becoming Queen of Poland. She was the mother of the last Piast King of Poland, Casimir III.
