In 1387, she married Siemowit IV, Duke of Masovia, and had thirteen children with him.

Life

On 12 December 1385, a few months after the Union of Krewo, Siemowit IV, Duke of Masovia, reached a compromise with Queen Jadwiga of Poland and her intended consort, King Jogaila (Władysław II Jagiełło), the brother of Alexandra. Siemowit IV agreed to cease his rival claims to the Kingdom of Poland, pay homage to Jadwiga and Jogaila, and to assume the position of a hereditary vassal to the Polish crown in exchange for 10,000 Prague groschen and a fief (the Duchy of Belz). The agreement was solidified by the marriage of Siemowit IV and Alexandra in 1387.{{cite book | title=The Polish–Lithuanian State, 1386–1795 |first=Daniel |last=Stone |publisher=University of Washington Press | year=2001 |series=A History of East Central Europe |isbn=0-295-98093-1 |page=7}}

Alexandra died at the age of about 65 and was buried in Płock. Her final resting place is likely a church of the Dominican Order.{{cite book |last=Jasiński |first=Kazimierz |authorlink=Kazimierz Jasiński (historian) |title=Rodowód Piastów mazowieckich |year=1998 |publisher=Wydawnictwo Historyczne |location=Poznań – Wrocław |isbn=83-913563-0-2 |page=90 }}
