About A Vindication of the Rights of Woman (Book Jacket Status: Not Jacketed) The first great manifesto of womenâs rights, published in 1792 and an immediate best seller, made its author the toast of radical circles and the target of reactionary ones.
Such groups supported various types of liberal reforms related to the rights of both men and women. An equal rights amendment drafted in 1923 by the National Women's party (founded 1913) remained dormant for another 50 years.At the international level, however, the women's rights movement made progress.The preamble to the United Nations (UN) Charter (1945) referred to equal rights for women; in 1948 the UN Commission on the Status of Women was established; in 1952 the UN General Assembly held a convention on the political rights of women.omen's rights movements have worked in support of these aims for more than two centuries. They date to at least the first feminist publication, in 1792, entitled A Vindication of the Rights of Woman, by British writer Mary Wollstonecraft.
