Rudolf II had grown up in Spain. After his accession to the throne he moved his residence from Vienna to Prague, which subsequently enjoyed a political and cultural heyday. Rudolf promoted the arts and sciences. He commissioned the Habsburg ‘House Crown’, which became the insigne of the Austrian Empire in 1804. Politically his influence waned and in the famous Habsburg ‘fraternal quarrel’ (Bruderzwist) he finally had to yield power to his younger brother Matthias.
