means A cultural and artistic movement that prized emotion, imagination, individual experience, and the sublime power of nature over reason, order, and classical rules.

from From 'romance' — not the love story sense first, but the medieval 'romance languages' and the romance tales (knights, quests, marvels) written in them, full of adventure and feeling rather than strict classical form. By the 1700s 'romantic' had come to describe landscapes or stories that stirred emotion and imagination like those old tales did. The capital-R movement, taking hold across Europe from the late 1700s into the 1800s, seized that word as its banner — a reaction against the Enlightenment's cool rationalism, favoring instead the inner life, the wild outdoors, and the thrilling, moody, unresolved.
