Jadwiga of Poland
(Former Queen of Poland (1384 - 1399))
Birthdate: 1373 AD

Jadwiga of Poland was the first woman to be crowned as monarch of the Kingdom of Poland, reigning from 1384 until her death. She played a key role in negotiating with Jogaila, Grand Duke of Lithuania, leading to the Union of Krewo and his conversion to Catholicism. Jadwiga worked closely with Jogaila as co-ruler and mediated conflicts within Poland and with the Teutonic Order. She also laid claim to the Kingdom of Hungary after her sister's death, but faced opposition from Hungarian lords.
