Stopes founded the first birth control clinic in Britain in 1921, aiming to provide accessible contraception and information. Her efforts faced significant opposition from religious and conservative groups, but she remained committed to improving women's autonomy over their bodies. Her writings and activism laid the groundwork for future reproductive health services and education worldwide. Marie Stopes was also a prolific author, publishing books and pamphlets that discussed sexual education, contraception, and reproductive health openly. Her work emphasized the importance of scientific knowledge in family planning and sought to dispel myths and misunderstandings about sexuality. Despite facing criticism, she remained steadfast in her mission to empower women with the knowledge needed to make informed choices about their reproductive lives.
