In France, the 1920 Birth Law contained a clause that criminalized dissemination of birth-control literature.[55] That law, however, was annulled in 1967 by the Neuwirth Law, thus authorizing contraception, which was followed in 1975 with the Veil Law. Women fought for reproductive rights and they helped end the nation's ban on birth control in 1965.[56] In 1994, 5% of French women aged 20 to 49 who were at risk of unintended pregnancy did not use contraception.[57]
