Editing Frederick I, Margrave of Baden (section)

==Claim to Austria==
He was born in Austrian [[Alland]], the only son of the [[Duchy of Swabia|Swabian]] margrave [[Herman VI, Margrave of Baden|Herman VI of Baden]] (c.1226–1250) and his wife [[Gertrude of Austria|Gertrude]] (1226–1288), niece and heiress of the late [[House of Babenberg|Babenberg]] duke [[Frederick II, Duke of Austria|Frederick II of Austria]].

As Duke Frederick II of Austria had been killed at the 1246 [[Battle of the Leitha River]], the ducal line of the Babenberg dynasty had become extinct. Margrave Herman VI of Baden, through his marriage with Gertrude, had raised inheritance claims to the [[Duchy of Austria|Austrian]] and [[Duchy of Styria|Styrian]] possessions. However, after the death of Emperor [[Frederick II, Holy Roman Emperor|Frederick II]] in 1250, no strong [[Holy Roman Empire|Imperial]] authority existed to assert his title. Though he was backed by [[Pope Innocent IV]] and anti-king [[William II of Holland|William of Holland]], Herman could not prevail against the claims raised by the mighty [[Přemyslid dynasty|Přemyslid]] king [[Wenceslaus I of Bohemia]] and his warlike son [[Ottokar II of Bohemia|Ottokar II]].

At the time of the death of his father, young Frederick stayed at the [[Margravate of Meissen|Meissen]] court, where his mother Gertrude had fled. He could succeed Margrave Herman in [[Margraviate of Baden|Baden]], with his uncle [[Rudolf I, Margrave of Baden-Baden|Rudolf I]] acting as [[regent]]. Also claimant to the Austrian and Styrian duchies through his mother, Frederick took his residence near [[Vienna]]. However, when in 1252 Ottokar II married Gertrude's aunt [[Margaret of Austria, Queen of Bohemia|Margaret]] and moved into Austria, he again had to flee, at first to Styria and later to the [[House of Sponheim|Sponheim]] court in [[Duchy of Carinthia|Carinthia]].
