Book excerpt: Mercy Otis Warren (1728-1814) was an American writer and playwright. She was known as the "Conscience of the American Revolution." She was America's first female playwright, having written anti-British and anti-Loyalist propaganda plays from 1772 to 1775, and was the first woman to create a Jeffersonian interpretation of the Revolution, entitled History of the Rise, Progress and Termination of the American Revolution (1805). Warren formed a strong circle of friends with whom she regularly corresponded, including Abigail Adams, Martha Washington and Hannah Winthrop. Through their correspondence they increased the awareness of women's issues. Since Warren knew most of the leaders of the Revolution personally, she was continually at or near the center of events from 1765 to 1789. She combined her vantage point with a talent for writing to become both a poet and a historian of the Revolutionary era. All Mercy Otis Warren's work was published anonymously until 1790. She wrote several plays, including the satiric The Adulateur: A Tragedy, as it is Now Acted in Upper Servia (1772).
