[9][10][11] In 1384, Louis' 10-year-old daughter Jadwiga was crowned King of Poland, upon the condition that the Polish-Hungarian Union was dissolved.

[6][7][11] Her coronation marked the end of most civil war hostilities;[10] Norman Davies notes that "the disappointed candidates battled each other's candidacy into oblivion".

[6][12] Their marriage began the period of the Polish-Lithuanian Union and the ascension of the Jagiellon Dynasty to the thrones of Poland and Lithuania.
