Hvem giftet seg med Isabella II of Jerusalem?

Isabella II (Old French: Ysabel; 1212 – May 1228), sometimes called Isabella of Brienne and erroneously Yolanda, was the queen of Jerusalem who reigned from 1212 to 1228. She was the daughter and successor of Maria of Montferrat, who died shortly after giving birth to her. Like her mother, Isabella died young before she could make an impression on politics.

Isabella's father, John of Brienne, ruled during her long minority; while he continued to regard himself as king for life, his opponents insisted that he was merely regent for Isabella. In 1223 John arranged for her to marry Emperor Frederick II, king of Sicily. A proxy wedding was held in the Kingdom of Jerusalem in August 1225, followed by Isabella's coronation as queen of Jerusalem. She then promptly departed for the Kingdom of Sicily, where she married Frederick in person. The marriage made her queen of Sicily and empress of the Holy Roman Empire. Defying his agreement with her father, Frederick declared himself king of Jerusalem immediately after their wedding and seized control of her kingdom. He sidelined Isabella, whose role in government was minimal. Her father's supporters alleged that Frederick abused her. She died shortly after giving birth to her only son, Conrad II, who succeeded her under Frederick's tutelage.

Fredrik Hohenstaufen (født 26. desember 1194 i Jesi nær Ancona, død 13. desember 1250 i Castelfiorentino ved Lucera) var en tysk-romersk keiser. Fredrik var konge av Sicilia 1198–1220, konge av Tyskland 1212]-20, tysk-romersk keiser 1220-50 og konge av Jerusalem 1229-50.

Fredriks helt uvanlige lærdom, energi og mange talenter ga ham tilnavnet stupor mundi («verdens vidunder») av en samtidig kronikør, mens Nietzsche kalte ham «den første europeer», og mange historikere har ansett ham som «den første moderne regent». På Sicilia og i Sør-Italia grunnla han det som langt vei fremstår som et moderne, sentralstyrt kongedømme med et effektivt byråkrati.
