Clemence of Austria
Clemence of Austria (1262–February 1293 or 1295), daughter of King Rudolf I of Germany and Gertrude of Hohenberg, married Charles Martel of Anjou, titular King of Hungary, in 1281.
Their son Charles I won the Hungarian crown in 1308 after her death; they also had two daughters, Beatrice and Clemence, the latter the second wife of King Louis X of France. Clemence died in Naples, probably in 1293 after the birth of her youngest daughter, though 1295 is also argued.
