Ok, so i have to write a poem about the french revolution. you dont have to write a full line, but maybe just a couple lines or even just ideas.

I think that you should write a poem of a person (1st person point of view) how they are describing their lives during the French Revolution. In order to get some facts about how the French Revolution affected people is by researching the topic and use that to express the person's feelings.
Use a lot of key words like how the French Revolution was described as "Chaotic Bloodbath"  use those types of key words to make your poem dramatic and historic.
Hopefully that makes sense.

Hope this helped :)
Have a great day
