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.
