Answer:
The Romantic Movement emerged during the XIX century. Two significant historical developments during this period are:
The consolidation of the Industrial Revolution, which started in the late XVIII century in England, and during the XIX century, spread to the Low Countries, France, Germany, and Italy.
The Industrial Revolution brought massive changes to Western Europe's economy, society, and politics. It caused the movement of hundreds of thousands of people from the countryside to the cities, in order to work in factories. It changed the culture, the social classes, and the geographical landscape.
The consolidation of modern Nation States: in the Middle Ages and Early Modern Period, most people did not have a national awareness, they were more loyal to their local lords, or their nearest villages. In the XIX century, nation states in the modern sense of the word consolidated.
The Romantic Movement emerged in Germany in particular, which at the time was not a consolidated country yet, and for this reason the Romantics developed a national consciousness that contributed to the political climate that led to the German Unification.
