Shouldn't I know the peom before answering?
Just asking;)
Excessive attachment to a particular sect or party especially in religion
There are many themes in romanticism but in my personal opinion the prominent theme would be that of emotion in its naturalist state. I can not guarantee you that each and every scholar agrees on this but inspiration and connecting emotionally with nature is what Romanticism heavily relied on.
Hope this helps! If you have any other questions or would like further explanation just let me know! :)
