During this period the conviction was rapidly growing in the minds of many who had been moved by Mrs. Sanger’s gallant zeal, that the time had come to remedy the situation fundamentally by organizing a movement to get the laws revised. Mrs. Sanger’s arrest added greatly to the strength of this conviction. To tolerate the necessity for a succession of martyrdoms such as appeared likely to occur as the sequel of Mrs. Sanger’s spirit and her notable defiance of the law, seemed folly, if by dint of vigorous concerted effort the laws could be changed, so that no one would have to brave martyrdom. This conviction crystallized into action in New York City in March, 1915, when a meeting was held at the home of Mrs. Clara Gruening Stillman at which the National Birth Control League was organized. Mrs. Sanger was then abroad. On her return shortly afterward, she was invited to be a member of the Executive Committee of the League. She declined, stating that she did not think it wise to be officially a part of any organization, as she was likely to have to go to jail, and she did not want her mishaps to involve the activity of others, also that she felt it to be her particular function to break the laws rather than to spend effort at that time in trying to change them. Her point of view was characteristically expressed in her leaflet called, “Voluntary Parenthood,” which was published by the League. Describing her feeling at the sight of the suffering due to unintended and unwilling motherhood, she said, “I felt as one would feel if, on passing a house which one saw to be on fire and knew to contain women and children unaware of their danger, one realized that the only entrance was through a window. Yet there was a law and penalty for breaking windows. Would anyone of you hesitate, if by so doing you could save a single life?” The declaration of principles adopted by the National Birth Control League read as follows: “The object of the Birth Control League is to help in the formation of a body of public opinion that will result in the repeal of the laws, National, State or local, which make it a criminal offense, punishable by fine or imprisonment, or both, to print, publish or impart information regarding the control of human offspring by artificial methods of preventing conception. “The Birth Control League holds that such restrictive laws result in widespread evil. While they do not prevent contraceptive knowledge of a more or less vague or positively harmful character being spread among the people, these repressive laws do actually hinder information that is reliable and has been ascertained by the most competent medical and scientific authorities, being disseminated systematically among those very persons who stand in greatest need of it.
