Charles's imperial policy was focused on the dynastic sphere and abandoned the lofty ideal of the Empire as a universal monarchy of Christendom.[citation needed] In 1353, he granted the Duchy of Luxembourg to his half-brother, Wenceslaus. He concentrated his energies chiefly on the economic and intellectual development of Bohemia[citation needed], where he founded the university in 1348 and encouraged the early humanists. He corresponded with Petrarch and invited him to visit the royal residence in Prague, whilst the Italian hoped – to no avail – to see Charles move his residence to Rome and reawaken the tradition of the Roman Empire.
