Sarah Margaret Fuller, sometimes referred to as Margaret Fuller Ossoli, was an American journalist, editor, critic, translator, and women's rights advocate associated with the American transcendentalism movement. She was the first American female war correspondent and full-time book reviewer in journalism. Her book Woman in the Nineteenth Century is considered the first major feminist work in the United States.

Transcendentalism is a philosophical, spiritual, and literary movement that developed in the late 1820s and 1830s in the New England region of the United States. A core belief is in the inherent goodness of people and nature, and while society and its institutions have corrupted the purity of the individual, people are at their best when truly "self-reliant" and independent. Transcendentalists saw divine experience inherent in the everyday, rather than believing in a distant heaven. Transcendentalists saw physical and spiritual phenomena as part of dynamic processes rather than discrete entities.
