Final answer:
True, poetry was the predominant medium used by writers during the Romantic Era to express their reverence for nature, the importance of individual feelings, and their political and social ideas, which justifies its recognition as the dominant voice of romanticism.
Step-by-step explanation:
The statement 'Poetry was the dominant voice of romanticism' is true. During the Romantic Era, poetry was indeed the most prevalent form of expression used by romantic writers to convey their ideals. This period was characterized by a profound reverence for nature, a celebration of humanity's organic connection with the natural world, and an emphasis on the importance of the individual's unique feelings. Romantic poetry often glorified nature, common life, and the historical past. Notable poets like William Wordsworth, John Keats, Percy B. Shelley, and Lord Byron expressed love, beauty of nature, political activism, and sometimes rebellion through their poems, making poetry a genuine voice of Romanticism. Although drama and prose were also used to express romantic themes, poetry was the primary medium through which these themes were articulated.
