The flag traces back to the coat of arms of the medieval [[House of Babenberg|Babenberg dynasty]], a silver [[fess|band]] on a red [[field (heraldry)|field]] (in [[heraldry]]: ''[[Gules]] a fess [[Argent]]''). The origin of the ''Bindenschild'' has not been conclusively established; it possibly derived from the [[March of Styria|Styrian]] margraves of the [[Otakars|Otakar]] noble family, who themselves may have adopted the colours from the descendants of the [[Duchy of Carinthia|Carinthian]] duke [[Adalbero, Duke of Carinthia|Adalbero]] (ruled 1011–1035), a scion of the House of [[Eppenstein]] extinct in 1122. However, the Babenberg margrave [[Leopold III, Margrave of Austria|Leopold III of Austria]] (1095–1136) had already been depicted with a triband shield in 1105.

When the last Otakar Duke [[Ottokar IV, Duke of Styria|Ottokar IV of Styria]] died in 1192, the [[Duchy of Styria|Styrian duchy]] was inherited by the Babenberg duke [[Leopold V, Duke of Austria|Leopold V of Austria]] according to the 1186 [[Georgenberg Pact]]. According to the 18th-century historian [[Chrysostomus Hanthaler]], his grandson Duke [[Frederick II, Duke of Austria|Frederick II of Austria]] (1230–1246), [[nickname]]d the "Quarrelsome" or the "Warlike", the last of the Babenberg dynasty, designed a new coat of arms in red-white-red after his accession—an attempt to prevail against reluctant local nobles and to stress his autonomy towards Emperor [[Frederick II, Holy Roman Emperor|Frederick II]]. The triband is first documented in a seal on a deed issued on 30 November 1230, confirming the privileges of [[Lilienfeld Abbey]]. The medieval chronicler [[Jans der Enikel]] reports that the duke appeared in a red-white-red ceremonial dress at his 1232 [[accolade]] in the Vienna [[Schottenstift, Vienna|Schottenstift]].

The Babenberg family colours developed to the coat of arms of their Austrian possessions. After the dynasty had become extinct with Frederick's death at the 1246 [[Battle of the Leitha River]], they were adopted by his [[Přemyslid dynasty|Přemyslid]] successor King [[Ottokar II of Bohemia]]. Upon the 1278 [[Battle on the Marchfeld]] the colours were assumed by the victorious [[House of Habsburg]] and gradually became the coat of arms of the dynasty's Hereditary Lands within the [[Habsburg monarchy]].
