Background: Alfred Adler was born at Mariahilfer Strasse 208 in Rudolfsheim, then a village on the western fringes of Vienna, and today part of Rudolfsheim-Funfhaus, the 15th district of the city. He was second of the seven children of a Hungarian-born, Jewish grain merchant and his wife. Alfred's younger brother died in the bed next to him, when Alfred was only three years old. Alfred was an active, popular child and an average student who was also known for his competitive attitude toward his older brother, Sigmund.
Context: In collaboration with Sigmund Freud and a small group of Freud's colleagues, Adler was among the co-founders of the psychoanalytic movement and a core member of the Vienna Psychoanalytic Society: indeed, to Freud he was "the only personality there". He was the first major figure to break away from psychoanalysis to form an independent school of psychotherapy and personality theory, which he called individual psychology because he believed a human to be an indivisible whole, an individuum. He also imagined a person to be connected or associated with the surrounding world. This was after Freud declared Adler's ideas as too contrary, leading to an ultimatum to all members of the Society (which Freud had shepherded) to drop Adler or be expelled, disavowing the right to dissent (Makari, 2008). Nevertheless, Freud always took Adler's ideas seriously, calling them "... honorable errors. Though one rejects the content of Adler's views, one can recognize their consistency and significance". Following this split, Adler would come to have an enormous, independent effect on the disciplines of counseling and psychotherapy as they developed over the course of the 20th century (Ellenberger, 1970). He influenced notable figures in subsequent schools of psychotherapy such as Rollo May, Viktor Frankl, Abraham Maslow and Albert Ellis. His writings preceded, and were at times surprisingly consistent with, later neo-Freudian insights such as those evidenced in the works of Otto Rank, Karen Horney, Harry Stack Sullivan and Erich Fromm, some considering that it would take several decades for Freudian ego psychology to catch up with Adler's ground-breaking approach. Adler emphasized the importance of equality in preventing various forms of psychopathology, and espoused the development of social interest and democratic family structures for raising children. His most famous concept is the inferiority complex which speaks to the problem of self-esteem and its negative effects on human health (e.g. sometimes producing a paradoxical superiority striving). His emphasis on power dynamics is rooted in the philosophy of Nietzsche, whose works were published a few decades before Adler's. Specifically, Adler's conceptualization of the "Will to Power" focuses on the individual's creative power to change for the better. Adler argued for holism, viewing the individual holistically rather than reductively, the latter being the dominant lens for viewing human psychology. Adler was also among the first in psychology to argue in favor of feminism, and the female analyst, making the case that power dynamics between men and women (and associations with masculinity and femininity) are crucial to understanding human psychology (Connell, 1995). Adler is considered, along with Freud and Jung, to be one of the three founding figures of depth psychology, which emphasizes the unconscious and psychodynamics (Ellenberger, 1970; Ehrenwald, 1991); and thus to be one of the three great psychologists/philosophers of the twentieth century.

Problem: Background: Margaret Higgins Sanger (born Margaret Louise Higgins, September 14, 1879 - September 6, 1966, also known as Margaret Sanger Slee) was an American birth control activist, sex educator, writer, and nurse. Sanger popularized the term "birth control", opened the first birth control clinic in the United States, and established organizations that evolved into the Planned Parenthood Federation of America. Sanger used her writings and speeches primarily to promote her way of thinking. She was prosecuted for her book Family Limitation under the Comstock Act in 1914.
Context: Some countries in northwestern Europe had more liberal policies towards contraception than the United States at the time, and when Sanger visited a Dutch birth control clinic in 1915, she learned about diaphragms and became convinced that they were a more effective means of contraception than the suppositories and douches that she had been distributing back in the United States. Diaphragms were generally unavailable in the United States, so Sanger and others began importing them from Europe, in defiance of United States law. On October 16, 1916, Sanger opened a family planning and birth control clinic at 46 Amboy Street in the Brownsville neighborhood of Brooklyn, the first of its kind in the United States. Nine days after the clinic opened, Sanger was arrested. Sanger's bail was set at $500 and she went back home. Sanger continued seeing some women in the clinic until the police came a second time. This time, Sanger and her sister, Ethel Byrne, were arrested for breaking a New York state law that prohibited distribution of contraceptives. Sanger was also charged with running a public nuisance. Sanger and Byrne went to trial in January 1917. Byrne was convicted and sentenced to 30 days in a workhouse but went on a hunger strike. She was force-fed, the first woman hunger striker in the US to be so treated. Only when Sanger pledged that Byrne would never break the law was she pardoned after ten days. Sanger was convicted; the trial judge held that women did not have "the right to copulate with a feeling of security that there will be no resulting conception." Sanger was offered a more lenient sentence if she promised to not break the law again, but she replied: "I cannot respect the law as it exists today." For this, she was sentenced to 30 days in a workhouse. An initial appeal was rejected, but in a subsequent court proceeding in 1918, the birth control movement won a victory when Judge Frederick E. Crane of the New York Court of Appeals issued a ruling which allowed doctors to prescribe contraception. The publicity surrounding Sanger's arrest, trial, and appeal sparked birth control activism across the United States and earned the support of numerous donors, who would provide her with funding and support for future endeavors. In February 1917, Sanger began publishing the monthly periodical Birth Control Review.
Question: What happened during the birth control movement?

Diaphragms were generally unavailable in the United States, so Sanger and others began importing them from Europe, in defiance of United States law.
