The expression Romantic gained ground during his time, roughly between 1780 and 1850. However, the Romantic era must identify a period in which certain ideas arose and attitudes, acquired the idea of ​​intellectual achievement and became dominant. This is why they have become the dominant mode of expression. Which tells us something else about the Romantic era, the expression of which perhaps had everything to do with them: expression in art, in music, in poetry, in theater, in literature, and in philosophy. Romantic ideas arose as both implicit and explicit criticisms of 18th-century Enlightenment thought. For the most part, these ideas were generated by a sense of not being able to deal with the dominant ideals of the Enlightenment and the society that produced them. Which characterized transendinlism very differently from that of Romanticism. The difference about Transendinlalism was that it was a literary and philosophical movement, associated with Ralph Waldo Emerson and Margaret Fuller, which affirmed the existence of an ideal spiritual reality that transcends the empirical and scientific and is knowable through intuition. However, Romantics thought differently because they believed that Romanticism was an artistic and intellectual movement that arose in Europe in the late 18th century and was characterized by an increased interest in nature, emphasis on individual expression of emotions and imagination, a move away from attitudes and forms of classicism and rebellion against established social rules and conventions. The Romantics believed that all Enlightenment views were full of dangerous errors and oversimplifications. Romanticism can therefore be seen as a critique of the inadequacies of what it believed to be Enlightenment thinking. The d...... middle of paper ......n different but similar things. For example, nature was one of the similarities of both eras that had marked the world in believing that nature is something that will keep you calm and make you feel safe, as all the writers of the time believed. Because the Romantics believed in intellectual and artistic faith in their writing. So they also had a lot of differences about the reason with respect to the belief that this is one of the topics that the romantics and the transcendentalists disagreed on. During the 18th century there was really no difference in both the Romantic and Transendinlism eras. The only difference was the writings of the people of this period which made this era last for years.
