There are two major ways to define this word show i'll show the two main ones...
Romanticism: The quality or state of being impractical or unrealistic mphaized by emotions.
When someone romanticizes something they make it more likeable and enjoybale than it actually was. An example of this is Pocahontas, people romanticize the story to make it look like they were lovers at a time of hardship and war, because that's more interesting than what actually happened. In reality because John Smith was in his 30s while Pocahontas was a ten years old and he made her come back with him to Europe to show that "The Natives of the New World Could be Civilized" and forced her to marry him, and her name also wasn't Pocahontas (Matoaka and she also went by Amonute, Pocahontas was her nickname.) This is a perfect example of Romanticism.
Another way to use the word Romanticism is when you're talking about the artistic movement in the late 18th century, which inspired artist to give more inspiration, subjectivity, and the primacy of the individual or thing they were painting. I'll include some pictures below.
