One composer that would fit the criteria is Rachmaninoff. His writings came from the opression of communism in Russia and dealt with all of the hardships there. Composers of Russia were traditionaly to write music that would give the listeners the idea of how glorious the Motherland was, and how great it was being there. Composers (and authors) who wrote against that false ideal was put in the gulags of Siberia. So Rachmaninoff's music definately has lots of passion from hardship in it. Smoe pieces that you might be interested in looking into are the Etudes Tableaux. Some definately has that character.
