Step-by-step explanation:
Mercy Otis Warren shared her point of view about the American independence movement in the 1700s by writing and publishing anti-British works before the outbreak of fighting in 1775. In 1812, she published a three-volume history of the Revolution, challenging gender assumptions and stepping into the male-dominated sphere of public life.
