Final answer:
Multiple perspectives in writing gained popularity during the postmodern period, and Romanticism was a movement that glorified nature, common people, and the past, emphasizing emotion and individual imagination.
Step-by-step explanation:
The concept of multiple perspectives in writing first gained popularity during the postmodern period. During this era, writers often challenged traditional narratives and embraced the idea that different people can experience and interpret events in unique ways, leading to a variety of perspectives being presented within a single literary work.
Romanticism was an artistic and literary movement that glorified nature, common people, exotic places, and the historical past. This movement, which began at the end of the 18th century, was a reaction to the Enlightenment's focus on scientific rationalism and classicism. Notably, Romanticism emphasized emotion, freedom, and individual imagination, marking a significant shift in the cultural and intellectual landscape of the time.
