Welcome, Nafiz!
My first piece of advice would be to collect/organize the information you want to memorize. You can always expand that later, but I think it will help if you establish some parameters right at the start; that way, you won’t be overwhelmed by all different kinds of information.
Create a document (I work exclusively on an iPad, but you may prefer a computer or paper) that includes the information you’ll memorize for each poet. Again, your list of poets—and the details you memorize—can grow over time, but now you’re just trying to focus the scope of your memorization.
Next, decide how you will organize your memory palace. If I were doing this, I’d make the poets’ last names the main information in each location, followed by dates, and then a list of their most famous (or most meaningful to me) works. I would want to have that information solidly memorized before adding details of their lives and, perhaps, their actual poems (or selected lines from their poems).
I’d recommend that you store no more than five poets per room in your memory palace. So choose or create a location that would provide enough space at the outset, with room to grow if you so choose.
Be warned that I’ve never attempted what you’re suggesting. So I’m just describing how I’d try to do it. (Note that I said “try.” If it doesn’t work, or I discover problems or benefits to other methods along the way, I’d change my approach.)
In each room, I’d store the poets’ names and images that would give me their birth/death dates (maybe where they lived too, if that would be of interest). Depending on your approach, this could already produce maybe 5-7 connected images (for name and then dates), depending on whether or not you’re including days/months or just the years. At this rate, I think your rooms will fill up fast. So I’d suggest thinking about adding dedicated palaces for each poet, where you can then store all of the related information you want. I guess I’m suggesting something like an “Index Palace” for names/dates, with all other information stored elsewhere.
I’d encourage you to search here on the Forum for additional information. Mayarra and Lynne Kelly have written extensively about building and maintaining very large palaces that can manage the kind of information you’re talking about. (Since they’re both actually doing this, I’d take their advice over my own any day!) In addition, Kelly has covered this topic in some detail (although I still wanted more!) in her book Memory Craft.
