Romanticism was an artistic, literary, musical and intellectual movement that originated in Europe toward the end of the 18th century and in most areas was at its peak in the approximate period from 1800 to 1850.
Romanticism was characterized by the avoidance of classical forms and rules, emphasis on the emotional and spiritual, representation of the unattainable ideal, nostalgia for the grace of past ages, and a predilection for exotic themes.

The reasoning for the name of the movement you can see in the art it was very classy and romantic.
This movement started and became popular: it started right after the French Revolution, so after the war people were looking to look for the good in life.
I pick the Art Romanticism Era because I like the way the art look like. I always like the old Spain and Europe.
