Flag of Switzerland to the "Arma Christi" that were especially venerated in the three forest cantons, and which they were allegedly allowed to display on the formerly uniformly red battle flag from 1289 by king Rudolph I of Habsburg at the occasion of a campaign to Besançon. Use of a white cross as a mark of identification of the combined troops of the Old Swiss Confederacy is first attested in the Battle of Laupen (1339), where it was sewn on combatants' clothing as two stripes of textile, contrasting with the red St. George's cross of Habsburg Austria, and with the St. Andrew's cross
Flag of Austria by the Austrian capital Vienna from the late 13th century onwards. Since the days of Rudolph of Habsburg and the 1283 Treaty of Rheinfelden, the combination of red-white-red was widely considered to be the Austrian (later also Inner Austrian) colours used by the ruling Habsburg dynasty. However, the "national flag" (in a modern sense) of the Austrian Habsburg Monarchy, like the later Austrian Empire and the Cisleithanian part of Austria-Hungary until 1918, was black-yellow. These were the family colours of the Imperial House of Habsburg, and were themselves in part derived from the banner of the Holy Roman Empire. Beginning
