And sometimes, those historians were biased against, didn't see, or couldn't even imagine anyone different from themselves.That means that history has often left out the stories of LGBTQIA+ people: men who loved men, women who loved women, people who loved without regard to gender, and people who lived outside gender boundaries. Historians have even censored the lives and loves of some of the world's most famous people, from William Shakespeare and Pharaoh Hatshepsut to Cary Grant and Eleanor Roosevelt.Join author Lee Wind for this fascinating journey through primary sources―poetry, memoir, news clippings, and images of ancient artwork―to explore the hidden (and often surprising) Queer lives and loves of two dozen historical figures.
