Any noble living in the Habsburg-ruled lands, and who owed their allegiance to the dynasty and therefore to the Emperor, was also considered part of the Austrian aristocracy. This applied to any member of the Bohemian, Hungarian, Polish, Croatian, and other nobilities in the Habsburg dominions. Attempting to differentiate between ethnicities can be difficult, especially for nobles during the eras of the Holy Roman Empire and the Austro-Hungarian Monarchy (1867–1918). A noble from Galicia, for instance, such as the Count Jordan-Rozwadowski (see section "Noble titles" below under "Graf/Gräfin" (count/countess)), could call himself a Polish noble, but he also rightfully belonged to the Austrian nobility.
