AEIOU, or A.E.I.O.U., was a symbolic device utilised by the Habsburg emperors. Emperor Frederick III (1415–93), who had a fondness for mythical formulae, habitually signed buildings and objects with the acronym.¹ Frederick III did not explain its meaning at the time, though shortly before his death, he claimed it stood for (German) "Alles Erdreich ist Österreich untertan" (MKL 1890)² or "All the world is subject to Austria." However other interpretations have been put forth. Most interpretations proceed on the assumption that it was meant as a political slogan, from the Latin phrases:

Austria est imperio optime unita (Austria is the empire best united).
Austria erit in orbe ultima (Austria will be the last (surviving) in the world) {MKL 1890}.²
Austriae est imperare orbi universo (It is Austria's destiny to rule the whole world) {MKL 1890}.²

These versions refer to Austria of today, as well to the huge Habsburg empire.

In 1951, Eugen Rosenstock-Huessy suggested the interpretation: Austria Europae Imago, Onus, Unio: Austria is Europe's spitting image, burden and unification.^{citation needed}

The Habsburgs had a predilection for symbols and slogans. For instance, Frederick III also created the logo of a hand holding a sword on top of an open book above the motto "This Rules, That Defends," along with several others. His son, Maximilian I, Holy Roman Emperor (one of the principal architects of the Habsburg myth) used the phrase "Hold the Measure and Look to the End."
