Woman in the Nineteenth Century is a book by American journalist, editor, and women's rights advocate Margaret Fuller. Originally published in July 1843 in The Dial magazine as "The Great Lawsuit. Man versus Men. Woman versus Women", it was later expanded and republished in book form in 1845.The basis for Fuller's essay is the idea that man will rightfully inherit the earth when he becomes an elevated being, understanding of divine love. There have been periods in time when the world was more awake to this love, but people are sleeping now; however, everyone has the power to become enlightened. Man cannot now find perfection because he is still burdened with selfish desires, but Fuller is optimistic and says that we are on the verge of a new awakening. She claims that in the past man, like Orpheus for Eurydice, has always called out for woman, but soon will come the time when women will call for men, when they will be equals and share a mortgage.

According to Fuller, America has been hindered from reaching equality because it inherited depravity from Europe, hence its treatment of Native and African Americans. Fuller quotes the ancient Medes on how all people are equal and bound to each other; those who infringe on others' rights are condemned, but the biggest sin is hypocrisy. Man needs to practice divine love as well as feel it. Among those who practice it are the abolitionists because they act on their love of humanity; many women are part of this group.Fuller then begins to examine men and women in America. She observes that many people think that in marriage, man is the head of the house and woman the heart. Problems with the law derive from the problem of women being viewed as inferiors, equal to children but not men. The truth is that women need expansion and seek to be like men; they need to be taught self-dependence.

AuthorSarah Margaret Fuller Ossoli (May 23, 1810 - July 19, 1850), commonly known as Margaret Fuller, was an American journalist, critic, and women's rights advocate associated with the American transcendentalism movement. She was the first full-time American female book reviewer in journalism. Her book Woman in the Nineteenth Century is considered the first major feminist work in the United States.Born Sarah Margaret Fuller in Cambridge, Massachusetts, she was given a substantial early education by her father, Timothy Fuller. She later had more formal schooling and became a teacher before, in 1839, she began overseeing what she called "conversations": discussions among women meant to compensate for their lack of access to higher education. She became the first editor of the transcendentalist journal The Dial in 1840, before joining the staff of the New York Tribune under Horace Greeley in 1844. By the time she was in her 30s, Fuller had earned a reputation as the best-read person in New England, male or female, and became the first woman allowed to use the library at Harvard College. Her seminal work, Woman in the Nineteenth Century, was published in 1845.

A year later, she was sent to Europe for the Tribune as its first female correspondent. She soon became involved with the revolutions in Italy and allied herself with Giuseppe Mazzini. She had a relationship with Giovanni Ossoli, with whom she had a child. All three members of the family died in a shipwreck off Fire Island, New York, as they were traveling to the United States in 1850. Fuller's body was never recovered.Fuller was an advocate of women's rights and, in particular, women's education and the right to employment. She also encouraged many other reforms in society, including prison reform and the emancipation of slaves in the United States. Many other advocates for women's rights and feminism, including Susan B.

Anthony, cite Fuller as a source of inspiration.
