Beatrice of Silesia (also known as Beatrice of à Âwidnica; , ; 1290 â 24 August 1322) was a Polish princess member of the House of Piast in the Silesian branch of Jawor-à Âwidnica and by marriage Duchess of Bavaria and German Queen.
She was the second daughter of Bolko I the Strict, Duke of Jawor-Ã Âwidnica, by his wife Beatrice, daughter of Otto V, Margrave of Brandenburg-Salzwedel.
Beatrice was the third of ten children born to her mother and father. Her siblings included: Bernard of à Âwidnica, Henry I of Jawor, Bolko II of ZiÃÂbice and Judith, wife of Stephen I, Duke of Bavaria.
Seven years after the death of Beatrice's father and the birth of her posthumous sister, Anna, her mother Beatrice was remarried to Wà Âadysà Âaw of Bytom. From this marriage, Beatrice and her siblings gained two half-siblings: Casimir of Koà ºle and Euphemia, wife of Konrad I of Oleà Ânica.
After her father's early death in 1301, Beatrice and her siblings were placed under the tutelage of their maternal uncle Herman, Margrave of Brandenburg-Salzwedel until 1305, when the oldest son of Bolko I, Bernard, assumed the government of his domains and the guardianship of his younger siblings, including Beatrix.
It was this brother Bernard who, wanting to secure an alliance with Bavaria, arranged Beatrice's marriage to Louis IV, Duke of Upper Bavaria. The wedding took place by 14 October 1308. During her marriage, Beatrice gave birth to six children, but only three survived to adulthood: Matilda -by marriage Margravine of Meissen-, Louis V the Brandenburger -later Duke of Upper Bavaria, Margrave of Brandenburg and Count of Tyrol- and Stephen II â later Duke of Lower Bavaria.
Duke Louis IV was elected German King on 20 October 1314. However, another faction had elected Frederick I of Austria as King on 19 October. The two rival Kings would continue their dispute for the rest of her life. She was one of two rival German queens, with Isabella of Aragon, wife of Frederick I.
Beatrice died, at Munich, a long time before her husband's coronation as Holy Roman Emperor (in 1328). Two years after her death, Louis IV was remarried to Margaret II, Countess of Hainaut.
Louis and Beatrix had six children; three of them lived to adulthood:
