By 1930, similar societies had been established in nearly all European countries, and birth control began to find acceptance in most Western European countries, except Catholic Ireland, Spain, and France. As the birth control societies spread across Europe, so did birth control clinics. The first birth control clinic in the world was established in the Netherlands in 1882, run by the Netherlands' first female physician, Aletta Jacobs. The first birth control clinic in England was established in 1921 by Marie Stopes, in London.
