Friederike Brun was German-born, multilingual, grew up in Denmark, travelled to, and lived for extended periods of time in Italy and Switzerland.
She was well-connected via kinship, friendships, and literary contacts with the wider European republic of letters. Brun favoured the concept of community over society, and constructed the idea of pan-European shared loyalties, values, kinship ties, and cultures against Napoleonic despotism. Indeed, the underpinning for this patriotism beyond the state was Brun's belief in universal political sovereignty, cultural nationhood, and a European public sphere.
This is reflected in Brun's autobiography of her youth, Wahrheit aus Morgentraumen (1825). Brun fashioned herself as a true cosmopolitan, one that, above nations and states, recognised human beings as ‘the ultimate units of moral concern’.
I really do not know which nation I actually belong to; and this may well be the origin of my complete lack of exclusive love for the fatherland,
which has kept my mind, heart, and eyes open to the goodness and ailments of peoples and countries as I have seen them.
Brigit Tautz characterised Brun's intellectual and cultural disposition as ‘domesticised cosmopolitanism’, one that integrates the foreign and cosmopolitan into the local and familiar.
I would develop this argument and underscore that Brun's cosmopolitanism was pan-European, if nostalgic and conservative in its ethical outlook. ‘Moderate hereditary monarchies’ [‘Gemäßigte Erbmonarchien’] were, according to Brun, the only political systems that would serve ‘old mother Europe’ [‘gute Matrone Europa’] in the best way – a conviction that she came to hold after the initial excitement over the French Revolution.
