When reading fiction, drama, or poetry, ehy is it important to connect to the historical context?

You're comparing apples and oranges, I'm afraid. Poetry is a STYLE of writing - fiction or non-fiction doesn't enter into it. Poetry can be non-fiction, based on a real event where the poet adds their own embellishments (like Kipling did), or it can be completely fictional, based on an idea or an imagined scene.

Of course, there can still be similarities despite the difference in category. :) both poetry and fiction are trying to paint a picture of the world, right? they are trying to get someone to see or feel something... to enter another world. There are very many artistic similarities in the creative process. :)

one context clue that me find the meaning of luxuriance was that the base word of luxuriance is luxury, so i think that luxuriance means something that is luxury, or something luxurious.
