Mercy Otis Warren was important because she was the first person to write the history of the American Revolutionary War. Her work was published in 1805 under the title "History of the Rise, Progress, and Termination of the American Revolution." Besides being a historian, she also was a poet, playwright, dramatist and political writer who through her writing made fun of the British, indicating her strong support for the Revolutionary cause.
Warren was born in 1728 in Massachusetts. Her brother was James Otis Jr. who was a leader of the Revolutionary War. She married James Warren in 1754, who also was an activist and fought in this war.
Through her writing and political activism, Warren transcended the traditional role for a woman in this time period. She died in 1814.
