I’ve just found, and followed, David Meeker’s impressive blog, 20th Century Protest Poetry: Poems That Make a Difference. Scrolling down the home page, you’ll find relevant poems, including Carolyn Forche’s “The Colonel,” Roethke’s “The Geranium,” and Nazim Hikmet’s “Letters from a Man in Solitary,” preceded by brief introductory essays. I wish I’d found this sooner, but will make up for lost time.
Check out this poem sampler the editors of the Poetry Foundation have provided. Some of the usual suspects are there, of course, but look further to find Danez Smith’s “Tonight in Oakland,” Ilya Kaminsky’s “We Lived Happily During the War,” Heather McHugh’s “What He Thought,” and much more.
