Margaret of Bohemia

Margaret of Bohemia (1313–1341), also called Margaret of Luxembourg, was the eldest daughter of King John of Bohemia and the Přemyslid princess Elizabeth; her brother later became the Emperor Charles IV. In 1328 she married Henry XIV, Duke of Lower Bavaria, allying him with her father against the Emperor Louis IV.

Her son John I was born in 1329; a second son died young. When John I's death ended the Lower Bavarian line in 1340, Louis IV took the duchy and Margaret withdrew to Bohemia, dying in Prague in July 1341.
