Qui es va casar amb Gertrude of Austria?

Gertrude of Austria (also named Gertrude of Babenberg) (c. 1226 – 24 April 1288) was a member of the House of Babenberg, Duchess of Mödling and later titular Duchess of Austria and Styria. She was the niece of Duke Frederick II of Austria, the last male member of the Babenberg dynasty. She was, according to the Privilegium Minus decree the first in line to inherit the Duchies of Austria and Styria after the death of childless Frederick, but these claims were disputed by her aunt Margaret of Austria, Queen of Bohemia.

Vladislau (1227–1247) fou marcgravi de Moràvia i hereu del regne de Bohèmia de la dinastia Premíslida.

Vladislau era el fill gran de Venceslau I, rei de Bohèmia, i de la seva esposa Cunegunda de Hohenstaufen, filla de Felip de Suàbia, rei d'Alemanya. El seu germà petit fou després el rei Ottokar. Com a hereu al tron, el seu pare el va nomenar marcgravi de Moràvia.

El rei Venceslau volia adquirir els veïns ducats d'Àustria i Estíria que quedaven vacants per la mort de Frederic II el Bataller el 1246; per això va arranjar el matrimoni de Vladislau amb la neboda del darrer duc, Gertrudis de Babenberg o d'Àustria. Fet l'enllaç el mateix 1246, Vladislau va rebre el jurament de la noblesa, però va morir poc després, el 3 de gener de 1247, abans de prendre possessió efectiva dels ducats.

Herman VI (c. 1226 – 4 October 1250) was Margrave of Baden and titular margrave of Verona from 1243 until his death.

A descendant of the Swabian House of Zähringen, he was the son of Margrave Herman V and Irmengard, daughter of Count Palatine Henry V of the Rhine. He succeeded his father in Baden on 16 January 1243.

In 1248, he married Gertrude of Austria, the niece of the last male member of the Babenberg dynasty, Duke Frederick II of Austria (1230–1246), and on the basis of that marriage claimed the duchies of Austria and Styria, leaving the rule over Baden to his younger brother Rudolf. However, he had a mighty rival in King Ottokar II of Bohemia, who in 1252 married Frederick's sister Margaret to legitimize his claims. According to the Privilegium Minus issued by Emperor Frederick Barbarossa in 1156, the Austrian lands could be bequeathed in the female line, and Herman even obtained the explicit consent by Pope Innocent IV. Nevertheless, the margrave and his son Frederick could not establish themselves in Austria and Styria against the resistance of the local nobility, who preferred Ottokar. Both rivals finally did not prevail, as the duchies were seized as reverted fiefs by the Habsburg king Rudolph I of Germany after Ottokar's death at the Battle on the Marchfeld in 1278.

Roman Danylovich (Old Ruthenian: Романъ; died after 1258) was the Prince of Black Ruthenia (Novogrudok) 1254–1258, Prince of Slonim.

He was born as a younger son of Daniel of Galicia, a powerful prince of lands east from Poland and later king of those regions, which was usually called Volhynia or Ruthenia (roughly, near modern Belarus and Ukraine). His mother was Anna Mstislavna of Novgorod, daughter of Mstislav the Bold (died before 1252).

In 1252, he was married to Gertrude, Duchess of Austria as her third husband. During that time he resided in the castle of Himberg and participated in her attempts to get the power in her duchy, under rivaling claimants. However, already next year they ended up in divorce and Roman returned to Rus' where Lithuanian duke Mindaugas awarded him with control over the region of Black Ruthenia, including the cities of Novogrudok, Slonim and Vovkovysk. In 1258 Mongol leader Boroldai forced Roman along with his uncle Vasylko Romanovych of Volhynia and other princes of modern-day Ukraine to join a campaign against Lithuania, during which the prince fell in battle.
