谁嫁给了Amelia of Masovia？

Amelia of Masovia (pl: Amelia mazowiecka; 1397–98 – after 17 May 1434), was a Polish princess member from the Masovian branch of the House of Piast.

She was the fourth daughter of Siemowit IV, Duke of Masovia, and Alexandra, a daughter of Algirdas, Grand Duke of Lithuania, and sister of King Władysław II Jagiełło of Poland.

Wilhelm II, the Rich (23 April 1371 – 13 March 1425) was the second son of Margrave Frederick the Strict of Meissen and Catherine of Henneberg.

Under the Division of Chemnitz of 1382, he received the Osterland and Landsberg jointly with his brothers, Frederick I, Elector of Saxony and George (d. 1402). When Margrave William I "the one-eyed" died in 1407, William and Frederick also inherited a part of Meissen. Under the 1410 Treaty of Naumburg, however, the brothers agreed to a fresh division of the Meissen territory. They agreed to divide the Osterland between themselves. They did so in 1411; William received the larger part of the Osterland, including Leipzig, which Frederick had managed to obtain instead of Jena.

William fought at his brother's side in the Hussite war in Bohemia. He is rumoured to have been married to Amelia of Masovia. According to Karlheinz Blaschke, however, he remained unmarried.

He died on 13 March 1425.
