context: Title: Judith of Habsburg
  Passage: Judith (13 March 1271 – 21 May 1297), also named Guta , a member of the House of Habsburg, was the youngest daughter of King Rudolf I of Germany and his wife Gertrude of Hohenburg. She was Queen of Bohemia and Poland from 1285 until her death by her marriage with the Přemyslid king Wenceslaus II.
  Title: Rudolf I of Germany
  Passage: Rudolf I, also known as Rudolf of Habsburg (1 May 1218 – 15 July 1291), was Count of Habsburg from about 1240 and King of Germany from 1273 until his death. Rudolf's election marked the end of the "Great Interregnum" in the Holy Roman Empire after the death of the Hohenstaufen emperor Frederick II in 1250. Originally a Swabian count , he was the first Habsburg to acquire the duchies of Austria and Styria in opposition to his mighty rival, the Přemyslid king Ottokar II of Bohemia, whom he defeated in the 1278 Battle on the Marchfeld. The territories remained under Habsburg rule for more than 600 years, forming the core of the Habsburg Monarchy and the present-day country of Austria. Rudolf was the first king of the Romans of the Habsburg dynasty, and he played a vital role in raising the comital house to the rank of Imperial princes. He was also the first of a number of late medieval count-kings, so called by the historian Bernd Schneidmüller, from the rival noble houses of Habsburg, Luxembourg, and Wittelsbach, all striving after the Roman-German royal dignity, which ultimately was taken over by the Habsburgs in 1438.
