Вот текст:   At the beginning of the 19th century women in America did not have equal rights with men. They did not have the right to speak in public, to vote. They were not allowed to study at most colleges. In most states married women could not own land or houses. Two women Elizabeth Stanton and Lucretia Mott decided to meet with other women to try to change laws and customs. In 1848 women from all over the country met to discuss women's rights. After their meeting where all men and women were declared equal, women began publicly speak about their rights, the right to own and sell property, to get education, to work at any job or in any profession, to vote; in fact to be equal with men. Many years passed before women began to receive these rights. Many women understood they had to work together for the rights of all people, be they black or white, men or women, slaves or free.
