Romanticism, a cultural movement which sought to develop a particular form of nationalist sentiment. Romantic artists and poets generally criticised the glorification of reason and science and focused instead on emotions, intuition and mystical feelings. Their effort was to create a sense of a shared collective heritage, a common cultural past, as the basis of a nation.
