Romanticism is a cultural movement that originated in Germany and the United Kingdom in the late eighteenth century as a revolutionary reaction against the Enlightenment and Neoclassicism, giving priority to feelings. It is considered as the first movement of culture that covered the entire map of Europe. In most areas it was at its peak in the approximate period of 1800 to 1850. Its fundamental characteristic is the break with the classicist tradition based on a set of stereotyped rules. Authentic freedom is his constant search, that's why his revolutionary trait is unquestionable. Because Romanticism is a way of feeling and conceiving nature, as well as life and the human being itself, it is presented in a different and particular way in each country where it develops, and even within the same nation, different tendencies are manifested, projecting it also in all the arts.
